YOU SIR ARE A TRUE PROFESSIONAL. YOUR VIDEOS ARE CLEAR, PRECISE, AND EXTREMELY KNOWLEDGEABLE. IT IS A PLEASURE TO WATCH AND LEARN.
JORYJORJANSEN CAUSEHEWAS#ONE i work were these engines are built in Texas so it is a blessing for someone to come with through with so much knowledge break it down to you yes you do yes you don't this is what we needs to be done keeps a lot of knowledge in perspective especially for the cat name
I run JD tractors. 4440 and 4640. Both had 20,000 hrs when cylinder sleeves started leaking coolant into the oil. Still had cross hatches on the sleeves. Could not see pulling them out putting new o rings in and not totally rebuilding engine. If i can keep farming i hope to get another 20 out of them....
We have a john Deere 6610 premium and got the engine rebuilt at 10 thousand hours as it was mixing oil and water. When we got it back john Deere said give it the hardest break in you can. It said pull the heaviest load possible for a 100 miles. So we did . We had it agitating slurry for a few days and then the big pull which was over 20 tons of concrete shuttering form work on a 40ft trailer. But on this journey it was unfortunately crashed and destroyed. It went upside and the engine started burning it's oil and blew.
when the Pistons are so worn out that they're swapping holes
Interesting analogy!
Started my first inframe on a 6nz c15. Have used several of your videos for help. Thank you!
A lot of questions were answered, sure helps me as a young Generation getting into Diesel .. Thanks
very much enjoy your vids. you come across as an honest and genuinely helpful dude. thanks
Spent all day clearing snow out from cabins and lodge.. and made sure to clean off my sattelite internet dish just so I could watch this video.
+Matthew Edwards I hope you liked it then.
Adept Ape sure did. Thanks!
Love your videos man. Very informative. Loads of useful points
Thank you 🙏🏻 for sharing your knowledge !
That’s informative and very helpful , thank you for the video
Thank you for the incredible information. I will go so much further because of you.
Ke Ga yes me too.
Thanks for sharing your great knowledge
Thank you sir for the good info. I got c-15 2009 been having the oil pressure low and I changed but still low
Thanks bro I love your videos. They all are very educational. The way you explain is so great. You need to be a teacher. 💯
Very good video, great amount of knowledgeable information !!
Great to see a Mechanic who likes to think too. Thanks 👍🏽
Gets up, first video is from Adept Ape......Cheers, Josh..
Mine is consuming like a gallon of oil every
2k miles,now I'm savings some money for A rebuild.
Great info!
Cool! Thanks, i was getting ready to rebuild my 3406 due to high miles but i am jus gonna wait til something breaks :D.. still pulling strong! :)
Drop the pan and 1, 3 .5 main bearing inspect and go from there
you should have your own channel on tv. great work
Great video as always
Now this makes me rethink if the shop I used convinced me to get a rebuild and I didn’t actually need it
They probably did
Hindsight is 20/20. Maybe it did, maybe it didn't. It's done now, go make some money and stay ahead of everything. Good luck and God bless!
Nice video, was worth watching.
Interesting how oil consumption changes when a truck goes from Over Highway use where speed, distance is the key, to being used on farm where it's under high loads, low speeds on soft roads, low speeds in softer fields where it can take all of the 400 HP to get out at 15mph.
There's a truck at work that was eating 8 gallons of oil per day. It had broken rings on I think 3 cylinders
good video, well spoken, helpful, thanks BXS
Your dam start ,to do all this in one take and not have to think about any of it..luv your content
it is true that not many mechanic think these days.
I appreciate your videos and am working on watching all of them. If you ever do anything on Detroit's please share!:)
In the market for a used 3/4 or 1ton pickup diesel. Good Stuff, Great Help, Good Tips 👍Thanks!
Good explanation. Just subbed
Thanks man
Love the channel bro!
Thank you.
Your video's are a great help.im learning a lot. I have a c12 that's in question. Still runs great.But has developed some extra blow by. But I'm thinking it needs valve seals.
I have a c15 acert with 1.3 million on it runs great , uses 2 gallons of 15/40 syn blend in 25000 miles . I have the money to build it , but I hate to touch it .
You can wait...remember he said 10,000 miles
Next oil change Drop the oil filter cut it open and remove a section of element squeeze out the oil in a vise and open the element use a good flashlight to inspect the element and look for metal brass and or what ever else, Brass/ copper showing could mean bearings
Nice video ! I work at a kenworth dealer we don't see those cats anymore lol ! Nothing but Cummings and paccars. Great video tho !
very good info. I have a m11 with what i feel is alot of blow by. but after seeing this i think im good for many more miles
Our m11 had very little blowby but was using alot of oil, it did have questionable low oil pressure but ran fine until i did an oil change and pieces of the engine fell out the plug hole. Pulled pan found scored crank, fretted bearing caps, piston cooler nozzels laying in oil pan. but hey it ran really good.
Most shops would do it just for the money. I appreciate your honesty.
awesome man thanks
Great video, thank you.
Hey big J! For the guys that need or want a complete engine overhaul, Wouldn't it be better to install a complete rebuilt engine instead of doing a complete In frame overhaul? Wouldn't it take less time to do that instead and come with a better warranty? I just want to give a huge thanks to you for giving back to the craft. Not a lot of guys out there willing to give back in order for others to become better at what they do .
If you can afford a new/rebuilt engine, that would be faster, but an inframe kit with new liners and pistons is a heck of a lot cheaper.
Awesome Video!🎥
Awesome video adept ape!! With what you said about blow by, does it count for a 7.3 idi?
Thanks bro, was really worried after seeing blow by in my engine...
The only thing you need to worry about is your rod and main bearings that protects you from a core because when the rod goes and puts a hole in the in the block and destroys the crank your core is no good it's the course fall Decor has a lot of money so it's cheaper just to roll Rod means in it and even the shops won't rebuild or they will rebuild your engine but they will not guarantee and after 900,000 miles because the crank is a little bit egg-shaped so they like to do it around 800,000 miles and then no guarantee the rebuilt else otherwise they won't so if you can't afford a rebuilt at least throw grow rods and main bearings in it and protect your crank and block yeah the Pistons and valves those things can come unglued dundun do whatever damage the Piston sleeve whatever but that has nothing to do with your core so the head does a little bit but yeah I mean it's not a big deal
I love the videos, so much to learn!👍🤜🤛✌
Great info
i like how you explained engine. because i have issued. i did test on cylinder but #6 is low pressure. now the mecinaic say i most have rebuild
So, if it isn't broke, don't fix it.
Yeah but if if you fix it before it throws a rod bearing or threw a rod through the block and put a hole in a box you can save yourself a lot of core money you got stop it before hand grenades
Famous words of my first employer.
Wrong, its called preventative maintenance.
I am taking over my dads truck and it’s been sitting for a minute and want to get one just to start fresh
Adept Ape , Absolutely The Best Explanations of Diesel Engines of anybody on the Internet and or anywhere else I have Found, Thank You For Your Expert Wisdom. I have Been A Mechanic All my Life more so as a Side Line but have been involved in Many things, Have even Been A Truck Driver when ever I needed to Fall Back on something from Time to Time But Also am Very Close to A Million Miles on that to. I am Per say Retired Now and looking at Motor Homes, I have Had Gas Motor Homes Before and am Now looking at a Diesel. I am looking at a 2005 Diesel MH with 90k Miles What would You Check on the Engine to Try and Determine its State of Condition or Ware, I have my List and I want to Know If I am Or Will be in the Same Ball Park as you would Be if you were Buying it. I have been told the One I am Looking At Does have a Service Record on the Engine. At This Time I do not Know what engine it Has But it is 350 HP and is a Cummings or a Cat. Thanks for your Input and your Absolutely Great Videos. God Bless America and Its Disabled Veterans.
Thanks!!!!!!!!!!!!!
Excellent tuition as always, you should consider teaching as you keep it simple and interesting. 😁
Thanks
Great video 👍🏽
If your replacing liner seals you should go ahead and do ring rods mains and new liners.reasoning for this to me is the fact that the most expensive part of shop work is labor. At 120+dollars an hour if there pulling sleeves youl save money in the long run to get the pistons and all other rebuild parts replaced.
Good advice and new oil delivery pump 😀
I love this guy
I recently completed an “in frame” (Pistons, rings, rod and main bearings and injectors) on my 95 Dodge Cummins 5.9 at 335k miles. The reasons I rebuilt were three fold. 1) Blowby from the crank case breather had become excessive to the point of coming out from under the truck and being visible around the front fenders and hood. 2) It would smoke when started at 90 degrees ambient temperature as bad as it had at 0 degrees when I first bought it. This smoking would only stop when the truck was hot and cruising but would return almost as soon as the engine was at idle. 3) It was running/idling/starting rougher than was normal.
When I got into the engine I found piston rings worn so badly that the end gap, which should have been .017”-027”, was between 3/16” and 1/4”! I was honestly surprised the engine was still running with what must have been terribly low compression. The cylinders were still round and were honed to remove the glazing before replacing pistons. (They could probably have been re-used but I didn’t want to risk anything) The bearings showed heavy, even wear but were not “damaged”. Rod and main journals were still pristine.
Following the rebuild there is very little blowby, no smoke beyond the quick puff when it is started and runs smoother than the day I brought it home.
I feel like by rebuilding when I did, I avoided the rings becoming so worn the pistons could have scored the cylinder walls. This video helped me pull the trigger on the “in frame”. Great expert, real world, advice.
Thank you for the informative comment. Glad to hear your engine is running well now.
Yes sir! Running like a champ and fun to drive again. (Being embarrassed by the constant blowby smoke takes away from the fun) Thanks for all the work and expertise you put into creating your videos! (By the way, sorry to use that dirty C word (Cummins) on your Cat Chanel!
@@manlyhelp thx bud same with mine now how much did this cost, an estimation thx bud
Including purchasing the ball hone and and a few other tools I needed, pistons, head bolts, bearings and the overhaul gasket set I was into the job about $1200-$1400. If I ever have to do the job again I will pull the engine rather than doing it as an “inframe”.

I like all your videos. They are educational. Question for you. I have a f250 6.9 idi natural aspiration, non turbo year 1985. The diafram on the cdr is broken an I found some oil in the air filter compartment. Can I turn a new cdr valve a 180 degrees and plug the hole in the intake and put a hose from the new cdr to a oil cath can and then another hose to another oil cath can and do not reconnect it to the intake? Or what do you think is my best option? Right now with a bad cdr is smoking but if I desconect it the smog stop by I can see blow by. Thanks one more time for your videos.👍👍👍
I generally find I have to rebuild mine when my brother in law has borrowed it and then worked a vintage tractor so hard one of the rods is sticking out of the fuel pump. I can diagnose that rebuild wihtout measuring equipment. (Just angry rant is all)
I rebuilt a 1,9 TDI 1Z from 1996 after nearly 400k km.
But it needed a rebuild badly:
- at least one broken/clogged injector, ran on 3 out of 4 cylinders.
- head gasket already leaking
- much other small stuff which was replaced since the engine was taken completely apart
runs now just fine again and hopefully another 100-400k km
I was looking at doing the same thing on 1.9 TDI bew but i guess it is not bad enough maybe in 2 years i will do it
So do you suggest to run to failure? We don't like that especially on marine engines.
One question about 3512 longevity do you have experience with this motor?
Is the bump up on the cruise control meant for idling at higher RPMs?
I have an old gm 5.7 olds diesel in a Cadillac Seville. Failed emissions at 60% opacity. Changed injectors and rebuilt pump. Cleaned fuel system from engine to tail. Anything else I should look for before I try again? It's been off the road for 6 years while I fix other stuff too. So when I go to crank again should I remove the glow plugs to bring the oil back in the system before firing it up again?
Nice video, I have a 2.5 tci diesel engine and it has a blowby, but is not consuming oil, the engine has lots of power, my mechanic tells me that the ingine needs a rebuild, but beside the blowby, the engine runs jus fine
My Cummins Big cam 400 started pushing water out of the overflow tube on top of the radiator.
Lots of bubbles when I took the cap off while it was running.
Head gasket?
After finally taking it apart I found bad head gasket and a cracked piston where it had been leaking water.
Bummer.
Honestly if the truck wasn’t pushing water out I would never had known because the truck still ran perfectly.
Now I get to learn how to fix it.
Great video. I have a question should you have the overhead ran every year
No is my answer but manufacture warranty and maintenance manual determine when. Big trucks need to run and log 10.000 miles a month to make money so if your doing that it may be good to have tech run the overhead
@Adept Ape
I have a mercedes om606 with a problem; upon startup it blows a lot of white smoke. it goes away after its warmed up but if you stomp on it you can sometimes still create the issue. engine code showed glow plugs. i have the engine apart so i can't do more diagnostics right now. do i need to rebuild the whole shabang? thank you, chris
So how do you go about messuring the blow by on cats does it have a sensor or something
Hey I'm all the way out in Jamaica and I have an 93 Isuzu npr that has the 4bd2t engine in it but it dragged piston last December should I rebuild or change it?...I've already done it twice before and it still has in the factory sleeves
I like your videos. thanks for share great information. My question for you is the next:. I have a f250 6.9 lt. I noticed some blue smoke when accelerate. the DCR valve is not good . I removed this one and blue smoke stop by I observed the. flow by. do you recommend to replace or just cancel it with a hose to the chassis area?
Check your engine thermostat and or running temperature, Sounds like its running cold although blue smoke is oil burning and this confuses a lot of techs. As well are you running the truck long and hard if you are not getting a good heat soak on the engine meaning if you just do short trips you can expect that
Need help,,, I have a C15 when the check engine light comes on I lose power but when I turn the engine off and then back on the check engine Light disappears so is hard to get a diagnostic because there's no check engine Light no more
Thank you sir. I had that question if to rebuild or not. No major issues just 1400000. Doesn’t really burn oil 2 gallons every 14k miles. I have a C-15 Accert. 2005. No problems with my engine love my Accert. It’s a money-making machine. Thanks
I have same motor same year,have had coolant pressure,consumption issues.
I dream of being an owner / operator and you being my dedicated engine man. Great video again!
I'm about to have the head on one of my boats CAT 3208T's due to (I think) a coolant hose failing, and subsequently finding out the temp alarm was in-op. Water in the oil. I'm hiring a proffessional mechanic to do the job. Are there any wear items you would recommend addressing while the head is off? The engines are 35 years old, and have 3500 hours on them, and I do not have detailed service records to reference.
Thanks for the great videos!
What about if truck runs good and doesent get hot but it pushes coolant out of the overflow tubeand have combustion in coolant
fun videos. Have learned about my 3126 from watching. Can you talk about the old mechanical 3406 engines sometime. Some say they are as good as the electronic engines.
+Ryan Burton I'm thinking of doing a 3406b/c video in the future as I get questions about them a lot.
Engine brake wouldn’t stop that much as the 3406E
Can you make something on Stop Leak on a CAT?? People say it works and might give me at least another month or two before I should do an inframe!
Can you talk about damper plate replacement on Ford Lehman marine engines? My engines vibrate a lot when at idle. They have 6500 hours on them.
Have you heard of any negative feedback from the remanufactured ford motors. I’m looking for one for my 7.3 L. I was pricing everything out and it’s definitely a lot cheaper for the amount of work I need. But I don’t know if it’s lesser quality when it’s titled remanufactured
Black smoke can be intercooler in manifold blocked.
If your considering a rebuild,would you recommend a reman motor,for an 05 cat c-15?would that be less expensive route than in frame?had friend spend 25000.00 on inframe .
We found alot a metal shaving on oil pan..
My mechanic said rebuild..so 13k later idk made the right choice..s60 480k miles
What’s is the difference between rebuild or overhaul ?
Good video
Question On Cummins 8.3, I took it in
for a skip with no check engine light on.
Currently have my RV at the Cummins dealer, they said it dropped a lifter and
needs a rebuild. That was after they replaced the injection Pump, Lift Pump
and #3 Injector all at $9k now being told that I need a rebuild for $14k and
they will eat $3k for the cost. Wondering why they did not check the
compression at the start instead of putting on all these parts. They also said I might need a turbo
if it's damaged from any metal in the system.
Ho w Mitch blow by can be caused by worn valve guides
Do you have any videos showing you diagnosing the cause of blow by and repairing it
I can't see not installing new power packs if you're already taking them out to replace the o-rings. It just seems like a wasted opportunity. Also time and more along with more down time when it finally has to have a rebuild
Small 60hp David brown tractor uk I spun a bearing but iam not going ti rebuild, just going to use emery cloth on the crank and hope for the best, what'd the worst that could happen throw a rod through the side?
I have a 3406e 5ek and the oil pressure is running at 50psi when engine is hot and at 1500rpm. I'm thinking that's a little low, what could be the issue? Engine has 1.1million km and 24k hrs. However blow-by (engine hot) is surprisingly low for those particular engines which says the engine is far from worn-out, so what could cause the low oil pressure? Any suggestions would be appreciated.
Sweet video bro
+Spooky Penguin69 Thank you young man. I think you are the first to comment twice now.
Adept Ape lol yeah i love your videos because as u know i want to be a diesle mechanic and you teach me alot
What if my engine throws the oil by the dipstick
When the compression is leaking enough past the rings that the engine won't start cold, it's time for a rebuild!
Mine starts fast not much cranking in cold weather and without plugging in -20 below but it smokes when i start it and then it clears maybe its the valves need to sealing? Compression feels good
I'd love for you to do my c15 acert rebuild when time comes
I got a 3 cylinder diesel ford tractor that needs a rebuild but she still runs good could use compression rings
I have an old Cummins big cam ntc350 started smoking a lot even at idle it would not clear up and had disel going into the oil , took it apart and found an injector with a broken needle so I put all of them new and ran the overhead , the smoking kept going but it did ran with a lot more power but when I checked the oil it keeps getting disel in there , what’s ur opinion is a rebuild worth it any ideas I’m trying to figure out what to do and fairly new in this
I have cummins isx 15 my truck in pete 386 2013. I have had radiator and water pump replaced recently and now after that I have coolant leaking I dont know the reason any guess by you?
It always confused me about repairs, maintenance and overhauls because dealers/mechanics talk in hours. When a gas car or truck used to hit 200k - 300k miles you were expecting an overhaul rebuild, or at least a partial. Lawnmowers, tillers, etc.... at 500 hours.
I'm contemplating a repower of a 1990 45 foot flybridge Post.. Right now it has the detroit 6V-71 'fuel pincher' (yeah right! compared to what!?) turbo diesels. And I want to get my economy up. Right now a duo of Cummins 5.9 12 valves are looking a pretty serious contender. What are the 24 valve 5.9's like? I like that they are pre DEF and pre DPF, but turn a really nice output in marine trim.. are they worth the extra complexity though?? They will be cooled by heat exchangers btw, I'm not having any raw salt water going thru my expensive engine blocks and manifolds! I'm wondering who to trust to obtain the engines for the repower? I know that the engines have to have different, marine bowl pistons fitted and run more boost than in truck / bus trim. I just want to know what the longevity of the 5.9 QSB engines are? Cheers
shoominati23 do you got room for the 8.3? You'll be happier.
What would you consider low oil pressure at idle with engine at operating temp on a c12?
In_process wondering this as well. Sitting at 20psi at idle and 40-45 at full throttle.
i dont get how the excess air out of the airbox breathers creates more crank pressure when the air is coming out of the breathers first,making the compresion less
I got a maxxforce7 international I got excessive amount of white smoke I can't drive it because of it, at first I was loosing coolant but now I don't (I threw head gasket sealer liquids) I replaced the water pump cus it was bad, I changed the turbo and egr but still the same problem, I pulled the dipstick out and muddy oil came out of it, I have a strong blow by even from the dipstick the truck turns on and runs fine but the white smoke is insane only when running
About for a 706 Farmall diesel tractor
