I graduated from high school in 1969 and went on wheat harvest that summer. I was hired as a truck driver. My truck was a 1955 Chevy 2 ton grain truck with a dump bed and a swapped in 350. We started in Oklahoma cutting wheat in Oklahoma, Kansas, Nebraska, North and South Dakota. The truck pulled a trailer with the combine on it with the harvest head in the bed of the truck. By the time we got to South Dakota, the truck could barely make it up a hill. In Fort Randall, SD, the boss and one of the other men pulled a head off the truck and repaired a cracked block between two cylinders with JB Weld. We continued on the harvest through North and South Dakota and returned home in south central Nebraska with the truck and repair intact. I've been a fan since I was 18.
Friend had a 80's Corvette that he stored over the winter with only water in it and no antifreeze. Cracked the block. We used jb weld and never had any problems at all...
I worked with a guy who threw a rod on his car just before his brother returned from the army. It broke out a good-sized piece out of the block down by the oil pan. The piece had oil pan bolt holes in it. He cleaned it up real good, put glue on it, bolted up to a new oil pan, didn't tell his brother, who was elated his brother would sell it to him because he always wanted that car. A few years later he bought it back. With brothers like that...LOL!
Many years ago, I overheated my old Oldsmobile beater that I used for a work car, resulting in a crack that ran between two of the cylinders. A friend of mine removed the head and patched up the block with JB Weld. It worked!
I had a '70 Maverick that had blown out part of the exhaust manifold gasket. It was very loud. The manifold bolts were hopelessly rusted, and I didn't have shop access... but I did have JB Weld. I filled the gap in and let it sit overnight, and the next afternoon I fired it up and it sounded nice and quiet like it was supposed to. It held and worked perfectly fine like that for a couple of years, then I ended up selling the car (I told the buyer). She never had it fixed, and it was fine like that for another 8 years. In that time, she had the muffler replaced, but the manifold joint was solid as a rock.
Excellent demonstration! My very first time using JB Weld was out of necessity. My very first car in 1978 was a 63 Rambler classic and it ran amazing, near bullet proof. However it had a hole in the bottom of the gas tank. ⛽️ The owner of the gas station I worked for suggested trying JB weld. We emptied the gas tank, properly prepped the exterior and did the repair, and it held up great. Six months later I traded that Rambler with my best friend who had a 65 Chevy Nova. Later he gave the Rambler to his sister, who used and abused it. 4 years later just before she sold it, I had the opportunity to check it out and that JB weld repair was still in place and holding, no joke! That experience made me a lifetime customer and I've used it on many projects over the years, because it works!
Your videos are the best. Very informative and factual. Thank you. Here is my JB weld story. It was 1978 and I flushed out the radiator in my 56 Chevy with a 235 6 cylinder in it. I just used water and like a 17 year old kid didn't put antifreeze in it yet. Well it got down to about 15 degrees Fahrenheit the next night. The engine block had a big crack going horizontally about 5 inches long on the passenger side of the block. Well I drained the radiator, cleaned it off really well and heated it up with a drop light. I talked to my high school auto shop teacher and he said try JB Weld since you have nothing to loose. To my surprise after appling JB Weld I had zero antifreeze leaks out of the block! It saved a broke high school from having to buy another block. I am sold on it.
You should drill an 1/8" hole at each end of the crack about 1/8" beyond where it looks like its going. This stops the crack from expanding and vibration of the crack from making it fail further.
@@jerrynewberry2823 I can verify drilling the hole works well it you get it in the correct spot. I did that on an old shovelhead Harley aluminum inner primary case. worked for almost 20 years till I had the money to have the aluminum crack welded up but a professional welder. That just held up for another 22 years.
Project Farm I'd let you borrow mine, but it's a lawn boy and probably wouldn't help. I see there is restore engine restorer, when are you going to run that in your green Craftsman? the only thing better than JB weld is JB quick
When I was a young (and dumb) kid, my friend and I took my moms car without permission, and drove it to the county fair. On the way home, I ran over something in the road, and it punctured the gas tank. Fortunately it was a little higher than halfway up the side of the tank. Frantically trying to save my secret, I repaired the gas tank with JB Weld, and for the remaining 5 years Mom had the car, it never leaked. I did eventually tell Mom what I had done, but I waited long enough to have my own home, so I wouldn’t get grounded, again. 🙄
If she hates that you are on this channel she does not realize what she's missing. If she didn't have you maybe she would be on here too...like me. PF is impressive too!
@@junelockard1695 I sometimes love machines more than humans. Doesn't happen much, but when it does I think I understand his wife's pain. . . But to lose out on the whole channel over that? A colossal loss. I agree.
Saved mine, too! Decades ago, my father in-law used JB Weld to patch some holes in my aluminum rowboat that wore through against some rocks while improperly docked at his summer cottage. He's no longer with us, but the boat still is!
I'm surprised it held up against the piston slapping it. I know the stuff is good at handling heat, but it's fairly brittle and doesn't like hard impacts. Usually a hard impact will cause it to crack and bust off. Very impressive test results.
I repaired a leaking Subaru sump which was rusted through. Lasted at least four years we own the car for - totally forgot about it between oil changes. That was a generic brand metal loaded epoxy, not jb weld.
Project Farm you ever tried Marine Tex?, I have never used it to repair an engine block my no means, but it's a good product, one time my dad's car had a hole in the water pump housing and we sold that car to friend of ours 5 years ago and according to our friend he hasn't had a single problem yet.
They have the white marine grade jb weld that works better in water for boats, I've used it and it's like concrete afterwards not as pliable as the regular one.
I know it's unlikely to get an answer 2 years later, but did you use the standard JB Weld? Does it still do great in water even if we now learn it's better? Saw these comments 5 months ago but for some reason I didn't ask what I wanted to know. If you don't ask...you may never know...
I used JB weld to repair a shallow well water pump I use out doors to pump water for my garden, pump froze in the fall one year and cracked the cast housing, fixed with JB weld and holding together still years later. Great video.
Amazing to come to one of your older videos and see how much your techniques have improved over the years. I enjoy how proficient you've become at tearing down, cleaning, and reassembling lawn mower engines.
I have used JB weld to fix a crack in a cast-iron engine block. Worked great. I also used JB to fix a small hole in copper tubing on the high pressure side of an AC unit. Both applications worked fine. When using JB Weld, make sure your area to "Weld" is totally clean & dry. I use rubbing alcohol to clean.
We had a 8in. Crack down the length of the engine block in our boat (inline 6 cylinder) we used wire mesh and jb weld. 7 years later, it's still running strong.(as well as a american engine from the 70's can anyway)
Thank you for your infor on your 6 inline, I intend to repair a Yamaha F115 4 cyc inline outboard, a rod connect bolt brokne, knocked a hole on block, otherwise great running motor.
@@dalepeter3016 4 years ago I snacked a whole in my block with cylinder no. 3. I've recently bought a replacement but it could be worth repairing for a spare... I'm not really willing to if the cylinder head was destroyed though. Costs nearly as much as a used engine to repair that.
@@DENicholsAutoBravado You are right, connecting rods and pistons is easy to replace, but if cylinder wall or head are no good, the block is toasted. I had a F115, 2004, through a rod, 1" hole on block wall, yet cyl. wall and piston are all good. With and new rod and full new bearings and rings, I got all 4 cyl 145 lbs. (replaced faulty oil pump and patch up the hole). I got a good F115.
Fully agree with you. I am working on a 73 tower power , all 6 are 135-140 lbs, she needs key, trim hooked up and control adjusted. As new motors are sooo expensive to buy and repair, l ll keep it for my 16' speed boat for more lake funs.
Ik you read most of your comments but chances are you won’t see this but I just wanted to let you know your content has to be the most interesting and reliable content ever!!!
I read your comment and thank you very much! It's never a waste to leave comments on the Project Farm channel. I value and read comments. Thanks again!
I had a tree branch hit the cooling fan on my tractor damaging the radiator. The radiator needs to come off and laid flat but jb weld did a very good and neat repair. It is still going strong after 2 years. New radiator for the tractor was going to be $ 750.00. JB weld less than 10 bucks. JB Weld radiator repair ... works good!
I had a leaky radiator but no jb weld on hand. I did have solder from when I replaced my hot water heater, so I repaired it with that and it's been holding up with 4 years of daily driving ever since. I did repair my dad's leaky radiator plastic side tank with jb and is holding up just fine.
One night I was driving north on I-75 in Dallas in between the Forest& Coit exits and I fell asleep at the wheel. I abruptly awoke on two wheels after hitting the center barrier wall, so I quickly put it back down on all 4 wheels and continued on my way! I promptly exited 635 west. All appeared wells I continued west.between Perston and Midway the temp started to go up rapidly so I pulled over. No damage to the perimeter of the car, but underneath the aluminum oil pan had a gash in it about 8 or 9 inches long and it had ripped out the drain plug Bolt. so I cleaned the gash well, applied a good heavy beed of JB weld, bought a slightly larger course thread Bolt for 60 cents retapped it and let it cure 24-36 hrs and drove it around like that for over a year with no problems. I'm a believer in the power of JB weld!
we call it i 75 The best-known section is the North Central Expressway, a name for a freeway section of U.S. Highway 75 between downtown Dallas and McKinney, Texas
I over heated a engine and cracked a small hole in the side of the block and wedged wood in it and filled it with jb weld it leaked till the engine warmed up but it worked
Damn, Jesse. Glad you're okay, man. Good that your vehicle made it, too. When I moved to Dallas, they were working on I-75. When I left, 11 years later, they were still working on it. Now, years later, I bet it's still being repaired or expanded. I've been back once and seen the amazing High Five Interchange.
Love this product even more! Thank you for all the rigorous testing and mockups. You put serious effort into each of your videos. No sponsors -just honest facts. My only request is more farm-a-bego!
The fact that the Piston was hitting the excess J-B Weld is even more impressive because it was putting an excess pressure that would not normally have been there
Used JB weld on a cracked noisy exhaust manifold on a 1972 350 chevy ran for a long time with no problems and quiet as a little church mouse. Good Stuff. Saved me over 100 dollars on a broken bracket on my dash temp control on my motorhome. thanks for the great videos.
In my opinion, I'm glad that you did NOT grind or sand the JB Weld off. That makes this a more valid, every day use test. That just shows the strength. What goes on, stays on....good job as always..
1994, put a dime size hole in my xr600 dirt bike engine case after crashing into a boulder. Drained oil, degreased thoroughly, and fixed it for the rest of bikes life.
@HONESTO UNO; If you're talking about old oil stains on concrete, this is the method I use. 1) Pour some mineral spirits on the area, enough to cover the entire stain but not really flooding it. 2) Dump floor dry/cat litter onto the mineral spirits approx. 3/4" deep. 3) Walk away. 4) Next day, sweep up floor dry and the stain should be gone. You may have to repeat the process if it don't remove all of the stain. I've been doing it this way for years. The 1st time was strictly by accident. Once I saw how well it removed some old oil stains I tried it in a different spot. Same results. No more stain. A good thing about doing it this way is I'm able to sweep up the floor dry and reuse it. Hope this helps.
+HONESTO UNO; If it's older concrete you can probably use a bit more mineral spirits. My garage is only 31 years old so it's not too bad floor surface wise. I do however 'use' my garage. It isn't generally used for actually parking vehicles in, but for a multitude of repairs. Make sure to use plenty of floor dry. Here's my 'theory' as to why this method works. Mineral spirits breaks up the old oil. Floor dry, when put on rather heavy, helps to keep the mineral spirits from evaporating rapidly, thus giving it time to work. The extra floor dry actually soaks up all of the mineral spirits making for a dry compound which can be reused. Like I said, it's only a theory. All I know is it has worked well for me. Please keep me posted.
Based on another video of yours, I used it to repair a broken faucet handle cartridge made of hard plastic. It has held up ever since. This required rotational bonding strength. So glad I saw that video. The faucet sat unusable for a year or more, as I didn’t know where to get a replacement or how to fix it. A few dollars and 24 hours did the trick! Thank you sir!
I have never found a better product than JB Weld for this type of application. Your experiment reminded me of a landlord I once had--a professional outboard mechanic--who used JB Weld to repair cylinder walls. He used similar technique to yours, but machined the wall smooth with a hone. I don't remember him using it to repair a head, but he may have done that as well. Very impressive video!
Used JB weld to fix a groove on crank shaft of Tecumseh snow blower 5 hp. Oil seal wore out/damaged crank. No leaks 3 years. Then thru rod. Thank you your experiments are always helpful!
I was traveling from California to North Carolina in 1992 and my Chevy Nova radiator spring a huge leak. My car left me stranded going through the final leg in the Appalachian mountain range. I tried several products and the only one that kept it together was the JB weld until I got to my new place. I love their product!
I have used JB weld to repair the end of a sway bar on a 99 Buick century. The sway bar ends tend to split overtime resulting in the need to buy a new sway bar. I used JB weld to attach the end back on and it was stronger than when it was broken with the links attached.
Lol. Holy crap. That's amazing to hear. But I don't doubt you. Especially after watching this video. I can't believe how much it sounded like a normal good running mower after he cleaned out the extra jb weld. I am impressed and it was funny just knowing the truth behind it all. He did a damn good job though.
My 89 Camaro with a 305 had a crack that pushed part of the block out and separated it, it wouldn't hold coolant but still ran amazing. I just put my second coat of jb weld on yesterday and I have yet to test it, but I have much more confidence now! Thanks brother for an awesome channel and true testing videos
JB Weld is an incredible product. 10 years ago, I used this product to repair a broken pestle from a stone mortar & pestle set. It is still holding up after 10 years of pounding spices! Thanks for a great video putting this product to a rigorous test.
Do it the way it's supposed to be done! I had a friend die using some duct tape on his filters one time and it got sucked up and him and his wife is dead now...
Wow. I've never seen a video of yours that disappointed me in any way whatsoever and I've been a mechanic my entire life. Respect and awe brother. You've earned it.
JB Weld saved me from having to spend $500 on a replacement radiator on my Kawasaki Sport Bike. Sealed the leaking hole in the radiator tank perfectly. I've also used it as a sort of body fill on some rusted out sections of the hood of my old Pontiac. This stuff is excellent.
Very impressive. I've used JB on numerous repairs but never thought it could withstand the pressure/temp of a cracked head repair. The only failure I've had with it was with a plastic radiator housing. Keep up the vids- much enjoyed!!
Maybe this experience will help someone who is stuck? Many years ago, I had a college kid for a tenant who worked a night job as a security guard. His funds were VERY tight. He developed a leak in the metal fuel tank of his chevy sedan. So here we go, flat of my back on a cold winter evening under an old chevy. We hit the leak with rough wet and dry paper and put a nice fat self-tapping screw into the "spot." We mixed and applied an epoxy putty product rated for fuel tank repair, smoothing out the product to cover several square inches in addition to the screw head. Once I was positive the leak was stopped, we placed a bare light bulb under the repair to speed up the curing process and kept an eye on it for ant sign of a leak. In a few hours, my college student went off to work and had no more trouble with his vechicle. Not the perfect repair I would have liked to perform but it worked until graduation, a year and a half later.
I was expecting a "and then a drop of fuel dropped onto the bare light bulb and it cracked and then it caught fire and the car and entire block went up in flames"
JB Weld saved us one hell of a tow bill on a motor home years ago near Yuma Arizona. We obviously had an object from the highway puncture the oil pan. Luckily it was 99 degrees at midnight. The stuff worked beautifully on a hole about the size of a quarter in the oil pan. We made it to our destination and we're able to locate a new oil pan. So glad it happened when it was a cool 99f and not the 121 high the next morning. Thanks for showing us what works and maybe more importantly what products do not.
Another great job! I race a 700 hp. TransAm series Camaro back in the 1990’s. I had an external oil filter and the aluminum housing cracked. I repaired it with J.B. weld. It never leaked! Incredible stuff!!!
I own a jeep cherokee and on the 2000 and 2001 model the heads are known to crack, mine did. I used JB weld to repair the crack and have been running my jeep for over six weeks now with no coolant going into my oil. worked for me! thank you JB.
I'm considering using it to repair a simulated crack on a piston, but this is really, really pushing the envelope! Thanks for watching the video and commenting!
Project Farm Sounds like a challenge! I have really enjoyed this series I have been watching right from a CZcams suggestion when you started your seafoam tests on your truck. Cheers
I feel the jb original better harder if your willing to wait .higher temp also .hope he has fire insurance if mowing in the garage with that fugitive from scrap yard .auto zone has two part stick I've used on steam boilers set I hour .
I bought a 1969 Jeep wagoner with a 350 Buick engine that had a cracked block from frost plug to frost plug. It actually pushed out one of the plugs more than halfway out and the block at that plug was completely cracked open about 1/16” gap. I cleaned the block the best I could. I coated both plugs and the block with JB Weld twice because the gap was so big the JB wanted to run down the crack to inside of the block. I ran that Jeep for over 2 years with NO ISSUES from the repair. I use that stuff on everything , it’s the best epoxy I ever used..... Your videos are AWESOME!
That's pretty awesome! I would have never figured JB weld would have held up in a combustion chamber! My had used it once over 20 years ago on a piece of his 1927 Model T's transmission housing, and it is still there today.
I just used JB Water Weld to repair a pin hole in a copper 1/2" supply into the house from a well pump & expansion tank. No leaks after 10 days... I have kitchen reno coming within the next 90 days. I need it to hold until then... So far so good. Thanks for a great video.
Great video! I used JB Weld to repair a 1 inch crack in the metal top of the radiator in my old Ford van. I sanded around the crack to rough up the surface, cleaned it really well with acetone, and applied the JB Weld in several thin coats allowing each coat to fully cure before the next was applied. I drove that van for years without another radiator issue!
I had a crack in my (plastic) intake manifold on my Saturn SW2 that was leaking coolant. I cleaned and buffed the surface around the crack and a piece of pvc, glued the PVC on with JB Weld, and voila, no more leak.
Most impressive-- we know JBW works on most common metals, but the epoxy apparently works on plastic, too. Good idea, thanks. * BTW, you used the PVC as a backer/reinforcement, but do you believe the plastic seam could have survived without the reinforcement?
About 20 years ago, I used JB weld to repair an aluminum intake manifold on a Toyota 4Y engine. The carburetor mounting studs had vibrated loose/wallowed out the threaded holes. Another tech had drilled/helicoiled the holes, but they did so WAY off center. As a result, it had a bad vacuum leak. I removed the studs, pulled out the Helicoils, and used JB Weld to fill in the holes and hold the studs in place. It worked well.
@@ProjectFarm My employer didn't think so. They wanted me to sell the customer a new intake manifold, for a lot more money. The customer wanted his lift repaired and running within a day. I sided with the customer.
Wow! Now this video brought back some memories. I am now 61. When I was roughly 13 a neighbor of mine had a very old riding mower. Cracked the head. Fixed it with JB Weld just like you did. Put it all back together, changed the oil and started it up. Ran great. Roughly 8 years later when I moved away, that damn mower was still going strong. Even though I knew little about engines then, I never would have thought that JB Weld would have worked or for that number of years! Thank you again. Glad I subscribed awhile back.
Great test! I keep JB Weld in my work shop and use often. I would never believed it would take the heat/stress of a cylinder head. I’ve it for many years and even thinned it with a little denatured alcohol to get into small cracks/fibrous material. Slightly warming w a heat gun makes it flow well and harden faster too.
Thank you. I was impressed. I didn't even know that it was epoxy at the time. We called it "Liquid Steel". I kept the car 2 more years and ran it hard. No leaks.
Thank you both very much for the positive comments! Please let me know if there is a way to improve the content too. I welcome constructive feedback! Thanks for watching the video and commenting!
Project Farm I'd say your doing it perfect I've noticed how Trends get popular on CZcams like the 1000 degree knife or the hydraulic press I'd bet before to long you have 1,000,000 subs I was looking at your video play list and your first videos got about a 1000 views but these engine tests get to a few hundred thousand views your starting a trend and it's awesome sorry for the long comment keep up the good work!
Thanks for this excellent test. It sure helps to have the assurance that if I need to make this kind of repair, JB Weld will be up to the task. Great job! And it's good to know that you're not sponsored by the manufacturer. An honest test!
This has become my favorite channel. You are to be highly commended for your impartiality and attention to detail,Your expression, "I,m Impressed!" can also apply to your subscribers opinions of your performance as well.
Wow, you do some great product tests Bro. I was wondering why you didn't sand it down for valve and piston clearance, but yet and still you do great detailed work. Very impressed with JB Weld!
You should test how different mix-ratios of the JB weld affects the strength. Like 50/50 of the steel to the hardener, 60/40, etc. I’ve always added slightly more hardener to heavier duty applications and it hasn’t let me down yet
Brother ,I've enjoyed your videos. I just recently did a j.b repair on the sidewalk of an 11 vertical shaft briggs motor. The crack accured,do to the pan bolts vibrating loose. What I found is one coat on the crack ,recracked due to engine vibration.. I simply clean the new cracked area,reapplied a little wider coating and it was a success. 👍🏻 thanks again for your videos.!!!
i've always known that JB Weld was awesome, but was always kinda curious about the "cracked cylinder " repair on the back of the wrapping. thank you for your experiment. it is good to know. I now know that JB Weld is a definite for the Tool Box.
i posted on your other video about prochem two part epoxy. i will send you some to test if you cant source it. i can all but promise it will outperform jbweld. love your videos buddy keep up the amazing work so informative and forget all those internet haters
Hi sir I've been using aroldite for many years and have found it to be a great product it's petrol resistant and heat resistant but it takes twelve hours to dry I'm very impressed by jb weld I will be getting some of this for future repairs many thanks for your video best regards Tony
I posted on another thread, but it might be useful here: A long while back, we used the JB Marine Weld to fill a corrosion hole between the exhaust and water jacket in a 6HP Evinrude. The block is cast aluminum. Fortunately the hole was acessible under the cover plate. Made sure the area was clean using acetone, and was properly prepped, reamed the hole to about 3/16" and cleaned of corrosion to bare metal. Let it cure for a couple days. Ran the motor probably a couple hundred hours. Sold it and the new owner is still running it.
I patched the plastic edge on my radiator and it lasted for a year before the crack decided to get worse. Also, many years ago I patched a GM 3.4L V6 Cylinder head with it and it ran perfectly until the car was rear ended and totaled. JB Weld FTW!
I used J-B to fix an expansion chamber I bought on E-bay and got stuffed with as it was cracked but I filled the crack with J B weld 5 years ago and its still good, yes I know its not under compression but still shows what can be done, Wouldnt wanna use it on a water cooled head though. But cool test. love the video's.
Thank you for the video. I have a valve cover on an car that I had tap a bolt for. Tapped it to large. I bought quick steel,but after seeing your video decided to use JB Weld. I am hoping the weld hold in fix a thread fastening. Thank you again for your time and video.
I once owned a Ford Pinto with a 2300 4 cylinder. The head gasket blew and it eroded the block between #1 and #2 cylinders. We cleaned it up and repaired it with JB Weld. Ran it for at least 2 years. Later replaced the rings and the JB Weld was still holding. Drove it another 3 years. That's a great product.
For short-term emergency situations, this would appear to be an excellent way out of a bad situation, but I'd be curious to see what would happen in the long-term. For example, what about cylinder heads and blocks on regular cars? Two potential issues might be the uniformity of mixture through the thickness and properly machining the JB-Weld to conserve the compression ratio and proper geometry to achieve the correct flame front. Interesting videos you have - food for thought and good reserve for those emergencies.
Great demo I’ve used it to repair metal gas tanks that were rusted through on older mowers and the results were no leaks from gasoline, heat, or vibration.
JB weld helped make a temporary fix on my cracked front differential housing! Waiting on the replacement housing to show up, but JB weld really doing the job.
jb weld works very well because it stays a bit flex able. While on the road with my semi the mounting ear on the alternator broke off. I used jb weld to fix it and it lasted 5 years before it came off aging. I have also fixed stripped threads in holes by filling it with jb then re drill and tap the hole.
It takes a little practice to fix threads with it but if done right it'll last a long time.I generally try and leave as much old thread as I can in there.But at other times I'll drill half the threads out over size and tap them a little with a larger tap to give the JB something to hold on too and then fill the hole and retap.It's tough to explain but you use the lower threads as a guide and the jb weld fils in the top portion and it works like a champ.
I actually did do this to a cracked head on a ford ranger. It worked beautifully. Ran better than when I bought it, and ran it for three years full time. It sold me. The crack was on two valve seats.
What I like about your series is your consistent methods of analysis, methods you improve with each new video. Best of all is your summary at the end, in which you review your test(s) for accuracy and validity, as well as improvements you could make. Although I began watching your series with mild skepticism, you clearly merit the interest of every DIY buff. Just imagine the money you have saved the DIY demographic across the country-- not to mention keeping the DIY products marketers on their toes, and marginally more honest. * On a minor note, are you in any way reimbursed or otherwise influenced by the "Amazon Influencer" program? What leads me to ask is your video in which you mixed 10 different oils of similar viscosity, comparing the results with Amazon Basics oil. It might have a simple explanation-- Amazon Basics is simply a non-descript, basic oil to use as a baseline for comparison, nothing more.
Thank you very much! I am in no way reimbursed or influenced. I am not part of the Amazon affiliate program and do not profit in any way when people purchase the products I test from Amazon or any other way.
JB Weld was a farmers wet dream come true when it came out. When all a dirt farmer had was some bailing wire and spit, hardly 5 bucks to his name, was 60 miles from town, stuck with a broken tractor and worn out muke, JB Weld could save their farm, their family. We are spoiled with abundance.
I have used JB weld for yrs, it works great. I made a repair on a transmission case a long time ago. A sticking up man hole cover ripped off the transmission pan. Damaged the case.The repair is still holding up today!!
LOL! Poor lawnmower! Unfortunately, some of the extreme testing I have planned will probably result in more of the same reactions! Hope you're enjoying the videos! Thanks for watching the video and commenting!
I have a lawn mower that's about 20 years old. It gave up a rod early on and punched a hole in the crankcase. My dad replaced the rod and piston, then used JB Weld to repair the block. It's used weekly and runs as good as new still today.
I graduated from high school in 1969 and went on wheat harvest that summer. I was hired as a truck driver. My truck was a 1955 Chevy 2 ton grain truck with a dump bed and a swapped in 350. We started in Oklahoma cutting wheat in Oklahoma, Kansas, Nebraska, North and South Dakota. The truck pulled a trailer with the combine on it with the harvest head in the bed of the truck. By the time we got to South Dakota, the truck could barely make it up a hill. In Fort Randall, SD, the boss and one of the other men pulled a head off the truck and repaired a cracked block between two cylinders with JB Weld. We continued on the harvest through North and South Dakota and returned home in south central Nebraska with the truck and repair intact. I've been a fan since I was 18.
Impressive!
Great story.
@@ProjectFarm Its funny how many times you say IMPRESSIVE
@@Fahleen I thought the same thing.
Friend had a 80's Corvette that he stored over the winter with only water in it and no antifreeze. Cracked the block. We used jb weld and never had any problems at all...
I put JB Weld on a 350 Chevy block that was cracked, that engine ran for years like that. Good shit!
Impressive!
I worked with a guy who threw a rod on his car just before his brother returned from the army. It broke out a good-sized piece out of the block down by the oil pan. The piece had oil pan bolt holes in it. He cleaned it up real good, put glue on it, bolted up to a new oil pan, didn't tell his brother, who was elated his brother would sell it to him because he always wanted that car. A few years later he bought it back. With brothers like that...LOL!
Me too but a honda
Many years ago, I overheated my old Oldsmobile beater that I used for a work car, resulting in a crack that ran between two of the cylinders. A friend of mine removed the head and patched up the block with JB Weld. It worked!
Iv done it too worked fo many years
I had a '70 Maverick that had blown out part of the exhaust manifold gasket. It was very loud. The manifold bolts were hopelessly rusted, and I didn't have shop access... but I did have JB Weld. I filled the gap in and let it sit overnight, and the next afternoon I fired it up and it sounded nice and quiet like it was supposed to. It held and worked perfectly fine like that for a couple of years, then I ended up selling the car (I told the buyer). She never had it fixed, and it was fine like that for another 8 years. In that time, she had the muffler replaced, but the manifold joint was solid as a rock.
Impressive repair!
Thank you for this info.
Excellent demonstration!
My very first time using JB Weld was out of necessity. My very first car in 1978 was a 63 Rambler classic and it ran amazing, near bullet proof. However it had a hole in the bottom of the gas tank. ⛽️ The owner of the gas station I worked for suggested trying JB weld. We emptied the gas tank, properly prepped the exterior and did the repair, and it held up great. Six months later I traded that Rambler with my best friend who had a 65 Chevy Nova. Later he gave the Rambler to his sister, who used and abused it.
4 years later just before she sold it, I had the opportunity to check it out and that JB weld repair was still in place and holding, no joke! That experience made me a lifetime customer and I've used it on many projects over the years, because it works!
Thanks! Thanks for sharing.
Hi, how to prepare the outer surface of the crank case for JB weld ?.
I mean how u prepared for your case ?
Your videos are the best. Very informative and factual. Thank you.
Here is my JB weld story.
It was 1978 and I flushed out the radiator in my 56 Chevy with a 235 6 cylinder in it. I just used water and like a 17 year old kid didn't put antifreeze in it yet. Well it got down to about 15 degrees Fahrenheit the next night. The engine block had a big crack going horizontally about 5 inches long on the passenger side of the block. Well I drained the radiator, cleaned it off really well and heated it up with a drop light. I talked to my high school auto shop teacher and he said try JB Weld since you have nothing to loose.
To my surprise after appling JB Weld I had zero antifreeze leaks out of the block! It saved a broke high school from having to buy another block.
I am sold on it.
Very impressive repair! Thank you for sharing this experience.
Ditto with my inboard engine on my boat
I just used jb weld on my radiator which had leak. Fixed like new.
You should drill an 1/8" hole at each end of the crack about 1/8" beyond where it looks like its going. This stops the crack from expanding and vibration of the crack from making it fail further.
@@jerrynewberry2823 I can verify drilling the hole works well it you get it in the correct spot. I did that on an old shovelhead Harley aluminum inner primary case. worked for almost 20 years till I had the money to have the aluminum crack welded up but a professional welder. That just held up for another 22 years.
No, you may not borrow my lawn mower.
LOL!!! Anyone else want to loan me your mower? More lawnmower torture tests to follow! Thanks for watching the video and commenting!
Project Farm I'd let you borrow mine, but it's a lawn boy and probably wouldn't help.
I see there is restore engine restorer, when are you going to run that in your green Craftsman?
the only thing better than JB weld is JB quick
You actually prefer J-B KwikWeld?
802 Garage
It is stronger in my experience. New test!
I thought about buying JB quickweld, but I've never used it! Thanks for watching the video and commenting!
You’re so knowledgeable and a very humble guy. I enjoy watching and learning from you. Keep up the great work!!
I appreciate that!
When I was a young (and dumb) kid, my friend and I took my moms car without permission, and drove it to the county fair.
On the way home, I ran over something in the road, and it punctured the gas tank. Fortunately it was a little higher than halfway up the side of the tank.
Frantically trying to save my secret, I repaired the gas tank with JB Weld, and for the remaining 5 years Mom had the car, it never leaked. I did eventually tell Mom what I had done, but I waited long enough to have my own home, so I wouldn’t get grounded, again. 🙄
YZMOTO #80 Hahaha. Had to acquire you own home so you wouldn't get grounded. That was a good laugh, thanks for that.
hahaha
😂😂 Well timed that revelation
this never happened

My wife hates that I found this channel. “What’s that, honey? I was watching someone cut apart a perfectly good motor and glue it back together”

If she hates that you are on this channel she does not realize what she's missing. If she didn't have you maybe she would be on here too...like me. PF is impressive too!
@@junelockard1695 I sometimes love machines more than humans. Doesn't happen much, but when it does I think I understand his wife's pain. . . But to lose out on the whole channel over that? A colossal loss. I agree.
Has it still held up?
JB Weld saved my marriage. Update. I am now divorced. No joke. Maybe I was having a premonition. :(
Now that's an impressive repair!!!
🤣
You have my condolences. ;-)
🤣
Saved mine, too! Decades ago, my father in-law used JB Weld to patch some holes in my aluminum rowboat that wore through against some rocks while improperly docked at his summer cottage. He's no longer with us, but the boat still is!
I'm surprised it held up against the piston slapping it. I know the stuff is good at handling heat, but it's fairly brittle and doesn't like hard impacts. Usually a hard impact will cause it to crack and bust off. Very impressive test results.
Thank you
I finally know what engine knocks sound like after watching a guy testing glue on his lawn mower. Thanks CZcams, great stuff.
lol!
I repaired a leaking Subaru sump which was rusted through. Lasted at least four years we own the car for - totally forgot about it between oil changes. That was a generic brand metal loaded epoxy, not jb weld.
You couldve just listened to a chevy running.

Project Farm lol can you pimp it out ahahaha
Project Farm you ever tried Marine Tex?, I have never used it to repair an engine block my no means, but it's a good product, one time my dad's car had a hole in the water pump housing and we sold that car to friend of ours 5 years ago and according to our friend he hasn't had a single problem yet.
Rexluna1 Ya think the warranty's voided yet?
Not that much real damage, could of been knocking off carbon buildup.
When I was in scouting, we had about 20 aluminum canoes, everyone of them had at least one patch of JB Weld. The stuff always worked great.
Thank you for sharing this experience!
They have the white marine grade jb weld that works better in water for boats, I've used it and it's like concrete afterwards not as pliable as the regular one.
I know it's unlikely to get an answer 2 years later, but did you use the standard JB Weld? Does it still do great in water even if we now learn it's better? Saw these comments 5 months ago but for some reason I didn't ask what I wanted to know.
If you don't ask...you may never know...
@@DENicholsAutoBravado If he don't answer, you may never know.
Ngl before watching the video I said HELL YEAH ITS GONNA WORK
I used JB weld to repair a shallow well water pump I use out doors to pump water for my garden, pump froze in the fall one year and cracked the cast housing, fixed with JB weld and holding together still years later. Great video.
Impressive repair!
Amazing to come to one of your older videos and see how much your techniques have improved over the years. I enjoy how proficient you've become at tearing down, cleaning, and reassembling lawn mower engines.
Thank you very much!
I have used JB weld to fix a crack in a cast-iron engine block. Worked great. I also used JB to fix a small hole in copper tubing on the high pressure side of an AC unit. Both applications worked fine. When using JB Weld, make sure your area to "Weld" is totally clean & dry. I use rubbing alcohol to clean.
Impressive repair!
We had a 8in. Crack down the length of the engine block in our boat (inline 6 cylinder) we used wire mesh and jb weld. 7 years later, it's still running strong.(as well as a american engine from the 70's can anyway)
Thank you for your infor on your 6 inline, I intend to repair a Yamaha F115 4 cyc inline outboard, a rod connect bolt brokne, knocked a hole on block, otherwise great running motor.
I used it over 10 years ago to repair a crack in the lower unit if my 140 hp outboard. It worked without problems.
@@dalepeter3016 4 years ago I snacked a whole in my block with cylinder no. 3. I've recently bought a replacement but it could be worth repairing for a spare... I'm not really willing to if the cylinder head was destroyed though. Costs nearly as much as a used engine to repair that.
@@DENicholsAutoBravado You are right, connecting rods and pistons is easy to replace, but if cylinder wall or head are no good, the block is toasted. I had a F115, 2004, through a rod, 1" hole on block wall, yet cyl. wall and piston are all good. With and new rod and full new bearings and rings, I got all 4 cyl 145 lbs. (replaced faulty oil pump and patch up the hole). I got a good F115.
Fully agree with you. I am working on a 73 tower power , all 6 are 135-140 lbs, she needs key, trim hooked up and control adjusted. As new motors are sooo expensive to buy and repair, l ll keep it for my 16' speed boat for more lake funs.
Ik you read most of your comments but chances are you won’t see this but I just wanted to let you know your content has to be the most interesting and reliable content ever!!!
I read your comment and thank you very much! It's never a waste to leave comments on the Project Farm channel. I value and read comments. Thanks again!
I had a tree branch hit the cooling fan on my tractor damaging the radiator. The radiator needs to come off and laid flat but jb weld did a very good and neat repair. It is still going strong after 2 years. New radiator for the tractor was going to be $ 750.00. JB weld less than 10 bucks. JB Weld radiator repair ... works good!
Impressive repair!
I had a leaky radiator but no jb weld on hand. I did have solder from when I replaced my hot water heater, so I repaired it with that and it's been holding up with 4 years of daily driving ever since. I did repair my dad's leaky radiator plastic side tank with jb and is holding up just fine.
One night I was driving north on I-75 in Dallas in between the Forest& Coit exits and I fell asleep at the wheel.
I abruptly awoke on two wheels after hitting the center barrier wall, so I quickly put it back down on all 4 wheels and continued on my way!
I promptly exited 635 west. All appeared wells I continued west.between Perston and Midway the temp started to go up rapidly so I pulled over.
No damage to the perimeter of the car, but underneath the aluminum oil pan had a gash in it about 8 or 9 inches long and it had ripped out the drain plug Bolt.
so I cleaned the gash well, applied a good heavy beed of JB weld, bought a slightly larger course thread Bolt for 60 cents retapped it and let it cure 24-36 hrs and drove it around like that for over a year with no problems.
I'm a believer in the power of JB weld!
I-75 Doesn't go thru Dallas
yes it does
we call it i 75 The best-known section is the North Central Expressway, a name for a freeway section of U.S. Highway 75 between downtown Dallas and McKinney, Texas
I over heated a engine and cracked a small hole in the side of the block and wedged wood in it and filled it with jb weld it leaked till the engine warmed up but it worked
Damn, Jesse. Glad you're okay, man. Good that your vehicle made it, too. When I moved to Dallas, they were working on I-75. When I left, 11 years later, they were still working on it. Now, years later, I bet it's still being repaired or expanded. I've been back once and seen the amazing High Five Interchange.
Love this product even more! Thank you for all the rigorous testing and mockups. You put serious effort into each of your videos. No sponsors -just honest facts. My only request is more farm-a-bego!
You are welcome! Thanks for the suggestion.
The fact that the Piston was hitting the excess J-B Weld is even more impressive because it was putting an excess pressure that would not normally have been there
Great point! Thank you
Used JB weld on a cracked noisy exhaust manifold on a 1972 350 chevy ran for a long time with no problems and quiet as a little church mouse. Good Stuff. Saved me over 100 dollars on a broken bracket on my dash temp control on my motorhome. thanks for the great videos.
“Massage it into the crack.”
Chromedome053 that’s what she said😈😈😈
HAHAHAHAHA!!!!!
My first thought was, I like this guy..
😏
That's a good crackkkk
It's amazing to see how much your videos have progressed over the years... You've more than earned every sub you have! Thank you Project Farm!
In my opinion, I'm glad that you did NOT grind or sand the JB Weld off. That makes this a more valid, every day use test. That just shows the strength. What goes on, stays on....good job as always..
Thanks!
1994, put a dime size hole in my xr600 dirt bike engine case after crashing into a boulder. Drained oil, degreased thoroughly, and fixed it for the rest of bikes life.

@HONESTO UNO;
If you're talking about old oil stains on concrete, this is the method I use.
1) Pour some mineral spirits on the area, enough to cover the entire stain but not really flooding it.
2) Dump floor dry/cat litter onto the mineral spirits approx. 3/4" deep.
3) Walk away.
4) Next day, sweep up floor dry and the stain should be gone. You may have to repeat the process if it don't remove all of the stain.
I've been doing it this way for years. The 1st time was strictly by accident. Once I saw how well it removed some old oil stains I tried it in a different spot. Same results. No more stain.
A good thing about doing it this way is I'm able to sweep up the floor dry and reuse it.
Hope this helps.
+HONESTO UNO;
If it's older concrete you can probably use a bit more mineral spirits. My garage is only 31 years old so it's not too bad floor surface wise.
I do however 'use' my garage. It isn't generally used for actually parking vehicles in, but for a multitude of repairs.
Make sure to use plenty of floor dry.
Here's my 'theory' as to why this method works.
Mineral spirits breaks up the old oil. Floor dry, when put on rather heavy, helps to keep the mineral spirits from evaporating rapidly, thus giving it time to work.
The extra floor dry actually soaks up all of the mineral spirits making for a dry compound which can be reused.
Like I said, it's only a theory.
All I know is it has worked well for me.
Please keep me posted.
im so glad i stumbled upon this channel. very interesting and straight forward.
Thanks for watching the video and commenting!
CJ, I agree. I'm actually learning something rather than being entertained. Kind of a Myth Busters sort of thing going on.
Based on another video of yours, I used it to repair a broken faucet handle cartridge made of hard plastic. It has held up ever since. This required rotational bonding strength. So glad I saw that video. The faucet sat unusable for a year or more, as I didn’t know where to get a replacement or how to fix it. A few dollars and 24 hours did the trick! Thank you sir!
Impressive repair! Thank you for the feedback
I have never found a better product than JB Weld for this type of application. Your experiment reminded me of a landlord I once had--a professional outboard mechanic--who used JB Weld to repair cylinder walls. He used similar technique to yours, but machined the wall smooth with a hone. I don't remember him using it to repair a head, but he may have done that as well. Very impressive video!
Brother you do amazing work!! utmost respect and gratitude for all the ways you help so many of us.
Thank you!
OMG, love that sigh at 2:10, when you admit to yourself that you just cut a hole in a cylinder head on purpose!!! Keep it up, love it!
Used JB weld to fix a groove on crank shaft of Tecumseh snow blower 5 hp. Oil seal wore out/damaged crank. No leaks 3 years. Then thru rod. Thank you your experiments are always helpful!
I was traveling from California to North Carolina in 1992 and my Chevy Nova radiator spring a huge leak. My car left me stranded going through the final leg in the Appalachian mountain range. I tried several products and the only one that kept it together was the JB weld until I got to my new place. I love their product!
Impressive repair! Thank you
I haven't watched this for a long time, and I must say I'm very impressed with how well JB Weld held up. :)
Thank you!
I have used JB weld to repair the end of a sway bar on a 99 Buick century. The sway bar ends tend to split overtime resulting in the need to buy a new sway bar. I used JB weld to attach the end back on and it was stronger than when it was broken with the links attached.
Thanks for sharing.
Lol. Holy crap. That's amazing to hear. But I don't doubt you. Especially after watching this video. I can't believe how much it sounded like a normal good running mower after he cleaned out the extra jb weld. I am impressed and it was funny just knowing the truth behind it all. He did a damn good job though.
My 89 Camaro with a 305 had a crack that pushed part of the block out and separated it, it wouldn't hold coolant but still ran amazing. I just put my second coat of jb weld on yesterday and I have yet to test it, but I have much more confidence now! Thanks brother for an awesome channel and true testing videos
Thanks for sharing!
JB Weld is an incredible product. 10 years ago, I used this product to repair a broken pestle from a stone mortar & pestle set. It is still holding up after 10 years of pounding spices! Thanks for a great video putting this product to a rigorous test.
Impressive repair! Thank you
hey, a cheap alternative to repair that darn blown piston on my helicopter! thanks man you saved me like $500!
007K as a certified helicopter maintainer, I approve of that plan
Don’t do it bro either weld it or braze it
Helo pistons ain’t cheap 😉
Kaboom
Do it the way it's supposed to be done! I had a friend die using some duct tape on his filters one time and it got sucked up and him and his wife is dead now...
I have used JB weld for years. I always have it on hand in my workshop. I love the product.
Thanks for watching!
Wow. I've never seen a video of yours that disappointed me in any way whatsoever and I've been a mechanic my entire life. Respect and awe brother. You've earned it.
Thank you
JB Weld saved me from having to spend $500 on a replacement radiator on my Kawasaki Sport Bike. Sealed the leaking hole in the radiator tank perfectly. I've also used it as a sort of body fill on some rusted out sections of the hood of my old Pontiac. This stuff is excellent.
Thanks for sharing.
Very impressive. I've used JB on numerous repairs but never thought it could withstand the pressure/temp of a cracked head repair. The only failure I've had with it was with a plastic radiator housing. Keep up the vids- much enjoyed!!
Thanks for watching the video and commenting!
Maybe this experience will help someone who is stuck? Many years ago, I had a college kid for a tenant who worked a night job as a security guard. His funds were VERY tight. He developed a leak in the metal fuel tank of his chevy sedan. So here we go, flat of my back on a cold winter evening under an old chevy. We hit the leak with rough wet and dry paper and put a nice fat self-tapping screw into the "spot." We mixed and applied an epoxy putty product rated for fuel tank repair, smoothing out the product to cover several square inches in addition to the screw head. Once I was positive the leak was stopped, we placed a bare light bulb under the repair to speed up the curing process and kept an eye on it for ant sign of a leak. In a few hours, my college student went off to work and had no more trouble with his vechicle. Not the perfect repair I would have liked to perform but it worked until graduation, a year and a half later.
That was nice of you to help and a great success story! Thanks for watching the video and commenting!
That was very nice of you too.Also glad to hear there's another smart person out there who'll use JB's stuff.
I was expecting a "and then a drop of fuel dropped onto the bare light bulb and it cracked and then it caught fire and the car and entire block went up in flames"
@@derkmerv6725 LOL.
Rub a bar of soap on a cracked gas tank. Works great
JB Weld saved us one hell of a tow bill on a motor home years ago near Yuma Arizona. We obviously had an object from the highway puncture the oil pan. Luckily it was 99 degrees at midnight. The stuff worked beautifully on a hole about the size of a quarter in the oil pan. We made it to our destination and we're able to locate a new oil pan. So glad it happened when it was a cool 99f and not the 121 high the next morning. Thanks for showing us what works and maybe more importantly what products do not.
Another great job! I race a 700 hp. TransAm series Camaro back in the 1990’s. I had an external oil filter and the aluminum housing cracked. I repaired it with J.B. weld. It never leaked! Incredible stuff!!!
Thanks! Thanks for sharing.
I own a jeep cherokee and on the 2000 and 2001 model the heads are known to crack, mine did. I used JB weld to repair the crack and have been running my jeep for over six weeks now with no coolant going into my oil. worked for me! thank you JB.
Impressive repair! Thanks for sharing this experience.
I have a Cherokee 2000 as well and the heads being known for cracking is not good to hear...
Wow! Very impressive. I have used JB for years but never to this extreme. Thanks for the cool and educational video.
I'm considering using it to repair a simulated crack on a piston, but this is really, really pushing the envelope! Thanks for watching the video and commenting!
Holy crap I need to see that please!
Project Farm Sounds like a challenge! I have really enjoyed this series I have been watching right from a CZcams suggestion when you started your seafoam tests on your truck. Cheers
I feel the jb original better harder if your willing to wait .higher temp also .hope he has fire insurance if mowing in the garage with that fugitive from scrap yard .auto zone has two part stick I've used on steam boilers set I hour .
yes please do this even if it fails it will show how good it can potentially be . have to share if you do
I've been watching your videos for years and I can't believe I am just discovering these older great videos now!
Glad you discovered them!
I bought a 1969 Jeep wagoner with a 350 Buick engine that had a cracked block from frost plug to frost plug.
It actually pushed out one of the plugs more than halfway out and the block at that plug was completely cracked open about 1/16” gap.
I cleaned the block the best I could. I coated both plugs and the block with JB Weld twice because the gap was so big the JB wanted to run down the crack to inside of the block.
I ran that Jeep for over 2 years with NO ISSUES from the repair. I use that stuff on everything , it’s the best epoxy I ever used.....
Your videos are AWESOME!
Thanks! Thanks for sharing.
That's pretty awesome! I would have never figured JB weld would have held up in a combustion chamber! My had used it once over 20 years ago on a piece of his 1927 Model T's transmission housing, and it is still there today.
Thank you!
My wife introduced me to J.B. Weld. it's absolutely amazing. Thank you for the proof!
Now don't tell us about massas....
I just used JB Water Weld to repair a pin hole in a copper 1/2" supply into the house from a well pump & expansion tank. No leaks after 10 days... I have kitchen reno coming within the next 90 days. I need it to hold until then... So far so good. Thanks for a great video.
You are welcome! Thanks for sharing.
Great video! I used JB Weld to repair a 1 inch crack in the metal top of the radiator in my old Ford van. I sanded around the crack to rough up the surface, cleaned it really well with acetone, and applied the JB Weld in several thin coats allowing each coat to fully cure before the next was applied. I drove that van for years without another radiator issue!
Thank you
I had a crack in my (plastic) intake manifold on my Saturn SW2 that was leaking coolant. I cleaned and buffed the surface around the crack and a piece of pvc, glued the PVC on with JB Weld, and voila, no more leak.
Most impressive-- we know JBW works on most common metals, but the epoxy apparently works on plastic, too. Good idea, thanks. * BTW, you used the PVC as a backer/reinforcement, but do you believe the plastic seam could have survived without the reinforcement?
About 20 years ago, I used JB weld to repair an aluminum intake manifold on a Toyota 4Y engine. The carburetor mounting studs had vibrated loose/wallowed out the threaded holes.
Another tech had drilled/helicoiled the holes, but they did so WAY off center.
As a result, it had a bad vacuum leak.
I removed the studs, pulled out the Helicoils, and used JB Weld to fill in the holes and hold the studs in place.
It worked well.
Impressive repair!!
@@ProjectFarm My employer didn't think so. They wanted me to sell the customer a new intake manifold, for a lot more money.
The customer wanted his lift repaired and running within a day. I sided with the customer.
Wow! Now this video brought back some memories. I am now 61. When I was roughly 13 a neighbor of mine had a very old riding mower. Cracked the head. Fixed it with JB Weld just like you did. Put it all back together, changed the oil and started it up. Ran great. Roughly 8 years later when I moved away, that damn mower was still going strong. Even though I knew little about engines then, I never would have thought that JB Weld would have worked or for that number of years! Thank you again. Glad I subscribed awhile back.
Great! Thank you!
Great test! I keep JB Weld in my work shop and use often. I would never believed it would take the heat/stress of a cylinder head. I’ve it for many years and even thinned it with a little denatured alcohol to get into small cracks/fibrous material. Slightly warming w a heat gun makes it flow well and harden faster too.
Thanks! Thanks for sharing.
Thank you. I was impressed. I didn't even know that it was epoxy at the time. We called it "Liquid Steel". I kept the car 2 more years and ran it hard. No leaks.
Thank you
I think I see an upcoming popular CZcamsr, these are entertaining so keep them coming!

to a few hundred thousand views your starting a trend and it's awesome sorry for the long comment keep up the good work!
Project Farm great and perfect job as always keep it up 👍
Thanks for this excellent test. It sure helps to have the assurance that if I need to make this kind of repair, JB Weld will be up to the task. Great job! And it's good to know that you're not sponsored by the manufacturer. An honest test!
Thanks!
This has become my favorite channel. You are to be highly commended for your impartiality and attention to detail,Your expression, "I,m Impressed!" can also apply to your subscribers opinions of your performance as well.
Thanks!
Wow, you do some great product tests Bro. I was wondering why you didn't sand it down for valve and piston clearance, but yet and still you do great detailed work. Very impressed with JB Weld!
Thank you!
JB Weld is indeed awesome stuff. I once used it to repair my oil pan after it was damaged when I ran over curb/median in the road.
Thank you
Had a rock go through my crankcase on my old xr 80... JB weld fixed it. 20 years later it cannot fix my life though
Great video, JB weld is on my list to fix leaking valve cover gasket on a v6 engine....many thanks, project guy i will look for more of your videos
You should test how different mix-ratios of the JB weld affects the strength. Like 50/50 of the steel to the hardener, 60/40, etc. I’ve always added slightly more hardener to heavier duty applications and it hasn’t let me down yet
Thank you for the video idea!
Brother ,I've enjoyed your videos. I just recently did a j.b repair on the sidewalk of an 11 vertical shaft briggs motor. The crack accured,do to the pan bolts vibrating loose. What I found is one coat on the crack ,recracked due to engine vibration.. I simply clean the new cracked area,reapplied a little wider coating and it was a success. 👍🏻 thanks again for your videos.!!!
Thanks so much!
It's amazing how many uses I find for JB Weld. Particularly since I own an aluminum boat! Great stuff!
Thanks for sharing.
I have used JB weld for decades. Best of its type by far. AS usual , your preparations were superb. Well Done!
Thank you
I used JB Weld on my wife's mouth, and I can finally watch You Tube in peace

🤣🤣🤣🤣🤣🤣🤣🤣🤣
time to find a heavy duty hydraulic hose and really get this jb weld tested to it's limits
LOL! Thanks for watching the video and commenting!
i've always known that JB Weld was awesome, but was always kinda curious about the "cracked cylinder " repair on the back of the wrapping. thank you for your experiment. it is good to know. I now know that JB Weld is a definite for the Tool Box.
You are welcome!
JBWELD IS THE BEST OF ALL . HAVE USED IT PERSONALLY FOR 60 YEARS . NEVER FOUND ANYTHING THAT COMES EVEN CLOSE. LOVE YOUR PROGRAM.
Thanks!
i posted on your other video about prochem two part epoxy. i will send you some to test if you cant source it. i can all but promise it will outperform jbweld. love your videos buddy keep up the amazing work so informative and forget all those internet haters
Hi sir I've been using aroldite for many years and have found it to be a great product it's petrol resistant and heat resistant but it takes twelve hours to dry I'm very impressed by jb weld I will be getting some of this for future repairs many thanks for your video best regards Tony
Tony, Thanks again. I'll have to try Aroldite. Always looking for better products. Regards, Todd
I posted on another thread, but it might be useful here:
A long while back, we used the JB Marine Weld to fill a corrosion hole between the exhaust and water jacket in a 6HP Evinrude. The block is cast aluminum. Fortunately the hole was acessible under the cover plate. Made sure the area was clean using acetone, and was properly prepped, reamed the hole to about 3/16" and cleaned of corrosion to bare metal. Let it cure for a couple days. Ran the motor probably a couple hundred hours. Sold it and the new owner is still running it.
Thanks for sharing.
I patched the plastic edge on my radiator and it lasted for a year before the crack decided to get worse. Also, many years ago I patched a GM 3.4L V6 Cylinder head with it and it ran perfectly until the car was rear ended and totaled. JB Weld FTW!
Thanks for sharing.
I really enjoy this channel. You do a lot of interesting and informative work and have influenced some of my buying decisions. Thank you.
Thanks and you are welcome!
I used J-B to fix an expansion chamber I bought on E-bay and got stuffed with as it was cracked but I filled the crack with J B weld 5 years ago and its still good, yes I know its not under compression but still shows what can be done, Wouldnt wanna use it on a water cooled head though. But cool test. love the video's.
Thanks for watching the video and commenting!
Why not a liquid cooled head? They run cooler temps.
Thank you for the video. I have a valve cover on an car that I had tap a bolt for. Tapped it to large. I bought quick steel,but after seeing your video decided to use JB Weld. I am hoping the weld hold in fix a thread fastening. Thank you again for your time and video.
Thank you!
I once owned a Ford Pinto with a 2300 4 cylinder. The head gasket blew and it eroded the block between #1 and #2 cylinders. We cleaned it up and repaired it with JB Weld. Ran it for at least 2 years. Later replaced the rings and the JB Weld was still holding. Drove it another 3 years. That's a great product.
Impressive repair!
To span large cracks, use steel wool and JB Weld.
Do you think it would hold the casing bolt surround on a briggs and stratton.thanks .
For short-term emergency situations, this would appear to be an excellent way out of a bad situation, but I'd be curious to see what would happen in the long-term. For example, what about cylinder heads and blocks on regular cars? Two potential issues might be the uniformity of mixture through the thickness and properly machining the JB-Weld to conserve the compression ratio and proper geometry to achieve the correct flame front. Interesting videos you have - food for thought and good reserve for those emergencies.
Great demo I’ve used it to repair metal gas tanks that were rusted through on older mowers and the results were no leaks from gasoline, heat, or vibration.
Thanks! Thanks for sharing.
JB weld helped make a temporary fix on my cracked front differential housing! Waiting on the replacement housing to show up, but JB weld really doing the job.
Thanks for sharing.
But the REAL question is, where do you get so many mowers to do all your videos? Keep 'em coming!!!
LOL! I buy them. The mowers and additives are expensive! Then again, education is a worthwhile investment. Thanks again!
Entertaining and educational!
jb weld works very well because it stays a bit flex able.
While on the road with my semi the mounting ear on the alternator broke off.
I used jb weld to fix it and it lasted 5 years before it came off aging.
I have also fixed stripped threads in holes by filling it with jb then re drill and tap the hole.
Impressive! I like the idea of fixing threads with it too! Great idea! Thanks for watching the video and commenting!
redone1995 as a machinist, I'll use that idea for stripped threads.
It takes a little practice to fix threads with it but if done right it'll last a long time.I generally try and leave as much old thread as I can in there.But at other times I'll drill half the threads out over size and tap them a little with a larger tap to give the JB something to hold on too and then fill the hole and retap.It's tough to explain but you use the lower threads as a guide and the jb weld fils in the top portion and it works like a champ.
I should add I usually only do it where seepage through a heli coil type repair is a concern.
My cylinder cracked and its leting water in do you tink this will work when it's hot
We only learn from our mistakes... and from watching you do the experiments. JB weld is awesome at fixing small holes in metal that will get hot.
Thanks for the feedback.
I actually did do this to a cracked head on a ford ranger. It worked beautifully. Ran better than when I bought it, and ran it for three years full time. It sold me. The crack was on two valve seats.
Thanks for sharing.
ive watched a good few of your videos and i feel so bad for that lawn mower lmao
LOL! Thanks for watching the video and commenting!
What I like about your series is your consistent methods of analysis, methods you improve with each new video. Best of all is your summary at the end, in which you review your test(s) for accuracy and validity, as well as improvements you could make. Although I began watching your series with mild skepticism, you clearly merit the interest of every DIY buff. Just imagine the money you have saved the DIY demographic across the country-- not to mention keeping the DIY products marketers on their toes, and marginally more honest.
* On a minor note, are you in any way reimbursed or otherwise influenced by the "Amazon Influencer" program? What leads me to ask is your video in which you mixed 10 different oils of similar viscosity, comparing the results with Amazon Basics oil. It might have a simple explanation-- Amazon Basics is simply a non-descript, basic oil to use as a baseline for comparison, nothing more.
Thank you very much! I am in no way reimbursed or influenced. I am not part of the Amazon affiliate program and do not profit in any way when people purchase the products I test from Amazon or any other way.
JB Weld was a farmers wet dream come true when it came out. When all a dirt farmer had was some bailing wire and spit, hardly 5 bucks to his name, was 60 miles from town, stuck with a broken tractor and worn out muke, JB Weld could save their farm, their family.
We are spoiled with abundance.
Great point! Thank you!
I have used JB weld for yrs, it works great. I made a repair on a transmission case a long time ago. A sticking up man hole cover ripped off the transmission pan. Damaged the case.The repair is still holding up today!!
Thanks for sharing.
I repaired my oil leaking manual transmission with J-B weld. 3 years later still runs like a champ.
Excellent! Thanks for sharing your experience with JB Weld.
I have also have a leak in my transmission from a crack and I can’t find a shop that welds transmissions so I’m thinking about trying jb weld but idk
I was yelling OH GOD NO when he cut that head with the angle grinder!
LOL! Poor lawnmower! Unfortunately, some of the extreme testing I have planned will probably result in more of the same reactions! Hope you're enjoying the videos! Thanks for watching the video and commenting!
I do very much, Thanks for the videos!
I have a lawn mower that's about 20 years old. It gave up a rod early on and punched a hole in the crankcase. My dad replaced the rod and piston, then used JB Weld to repair the block. It's used weekly and runs as good as new still today.
Nice! Thanks for sharing.
Your videos are the embodiment of Consumer Reports and Mythbusters combined. Outstanding work across the board.
Thanks so much!
