Spun rod bearing??? FIX IT!!!
VloĆŸit
- Äas pĆidĂĄn 15. 01. 2020
- I didn't know you could do this but you can fix a spun rod bearing!!! So my brother was driving his car and it was low on oil, hit a corner fast and pushed the oil to one side of the oil pan, and it ran dry for a couple seconds. Then a slight rod knock came a couple minutes later. We ended up pulling the oil pan, taking all the connecting rod caps off and found the one the was spun. Sanded all the surfaces as smooth as we could get them with 1000 grit sandpaper and bought a brand new oem bearing, checked clearances everything looked good, cleaned the oil pan, and went back together great (with assembly oil on everything so it didn't do it again!).. Im sure it won't last forever but it will get you going until you can find out what you're going to do. Its lasted so far on his car which is turbo'd now and won't have an easy life. The bearing was not that expensive and was well worth a try to get it going again.
This was probably best case scenario, it happened like 10 min from home and only lost pressure for about 3 seconds at a lower RPM around a turn. Also we SANDED for HOURS to get things smooth with a fine sandpaper, our clearances were good and it wasn't too damaged to start with. So depending on what your working with, this may work, and may not!!!
Check you oil....
Thanks for watching!!

I had no clue you could do that through the oil pan opening. I thought you would have to take the entire engine apart. Awesome!
sure you can i`ve done it before with very good success
Just remove the spark plug so you can push it up.
@@nevinkuser9892push what up?
This is what I needed to see. Just got the faint knock in my 99 Tacoma. Parked it asap. Gonna find that rod and replace it!!!
Thanks for the video bud, now ive got a weekend start point for the truck.. hope the cars doin well.
Awesome đ job. It's good to see you guys fix this together.
This video is super inspiring even tho I know sh$t about engines but was seeing if my rod bearing on my 250k sierra could be repaired instead of replaced and you guys are awesome thank you!
Of course the only car I ever spun a bearing on, I have to remove the rear main seal housing, which means tranny gotta come off. lol. Im glad it went good brother!
Iâve donât this twice on two Kias, both lasted over 2 years now & are still going strong, Just change the oil & filter every 1000 miles for the first 5000 miles & also stick a powerful magnet on the bottom of the oil pan to trap any floating metal thatâs inside the engine passages, that way it doesnât cause further damage, Sand the crank from 430 grit all the way up to 2500 grit, Take a while & is exhausting but it is very possible
wanting to try this on my lancer, car starts ,but engine is very hard to turn by hand ,only with powerful battery
Nice to see that Garth from Wayneâs world is doing good these days! Haha jokes aside thanks the for the video! Really helped alot
Party on Dude!
Rock on dudes! Way to ghetto fix that bad boy. No need to get a new engine... just ghetto fix it again đ!!!
Brown 3M scotch pad cut to side of journal use wd-40 or Gasoline as cutting lube.
If you must do this, count how many swipes going back n forth treating like sanding copper pipe for soldering. Remember 33* 3 points of sanding. Count 10, go 33* count 10 go 33* . Repeat so to keep journal OD somewhat consistent. Enjoy.
Always keep 2 of the 1 L bottles of Oil in the boot, for such an occasion! đ
I love how he said âweâre gunna buff that outâ đđđđđđ
Thats neat you fixed that. Even I failed at this once on a Honda. But recently I've learned so much and how I did it wrong back then on the Civic. I sold the car the guy that bought it ran a red light in it a week later so I know he fixed it quick. He knew. I also misprinted my phone number when he pulled in he told me my number isn't right and that he like a bicycle lock he figured it out after a day he said all day lol. Wow. My point today was that after seeing this you could have re centered the same bearing back in place after you smoothed the crank . Meaning you didn't need a new one . If it was damaged then yeah,then guage and get one. But thats nest you did this I slipped three of my cars and sold them over nothing. It the bearing was just slipped and came loose just needed placed back then oil.. but no0 sold the whole car four times over sometimes simple odd stuff . My neon engine will need a bearing one day and I'm not throwing it out. Sorry. Il try what you did plus..
Wasn't a permanent fix. Just till they could get a new engine.
2 minutes in and im waiting for him to drop that damn bearing again
It's not the crank that causes issues. It's that people don't spend anytime on doing the Rod end...That part has to be clean of all the old material. Then polished. If the clearance is a little over. You can use Blue Loctite. That will give you some insurance...The trick with loctite. You have to install the bearings right there and then, before it dries.
And don't go stupid crazy with it. Just a very small amount is all you need..I done several this way...One lasted 5 years before I sold it..It was still running good...
Yeup. Planned on doing the same thing on my Chevy 5.7 but as I pulled out the spun bearing I noticed one of the oil passthrough's in the crankshaft was clogged with metal debris and all the other bearings were scorched and ruff. I also noticed the camshaft looking worn and possibly scorched also... ill be having a new crate engine coming soonđ
Great job
I am wondering if you replaced all four bearings if it will last longer... Having the same prob. Thanks!!!
Maybe try some valve Polishing Compound for situations like this(Carefully)
I got a 07 PT same issue just happened, trying this out this week đ±
It worked on my PT, saved me from buying a new car
I remember I spun a rod and was told by a mechanic I need a new crankshaft, then a few weeks later he told me to get a new engine
Repair ,maintanance,i agree
Heâs 100% correct
i would take one of those 1/2 inch ratchets with the grooves cut into the handle and tap them into the surface of the rod and cap for taking up any cleaance. There is a procedure to fit the bearing tight and that includes some super metal mix to apply under the rod bearing. That can bring ti back to original without removing any more.
What did y'all use to resurface the crankrod and bearing cap?
I have a Chevy 1996 5.7L 350 Sb is knocking noise. I took the oil pan out and found metal residual. I was told I need a new engine. The engine turn on and drives. Any advice please. Thanks
Can you please give us an update - has the fix held up?
Hey, quick question, besides draining the oil prior to replacing the Rod bearings , did you do anything to flush out the old oil/ metal particecls off the engine before firing it up with new bearings and oil? I'm doing this as well but I want to make sure I don't spun another Rod bearing because of any metal particecls left in there.
Just clean out the pickup tube. Any thing that can get through that screen will be caught by the filter.
you say , go find another engine?! from the junkyard?! and after that....find another one?....just don't let them run out of oil *lol*
Question, and thanks for the content . Greatly appreciate it. When the Rod bearing Caps are some what damaged/scraped up (not major) from a spun bearing can we use some 600/800/1500 wet sandpaper on it, as we do to polish the journals? or does it call for a new Rod bearing cap? Thanks
Rod bearing caps are matched to each rod and need to be kept together and reinstalled the exact same way they came off. So you really cant get a 'new' cap, because they're matched(rod & cap). But you can totally use sandpaper and try to smooth out the surface a littleđ
@@PostPros Greatly appreciate the reply! Thanks for the support, and I'll clean those caps up.
having the same issue in my 89 accord with the 2500-3k rpm thing only around 1/4 throttle and it does it
Ayy, my man. Any indication of how long that fix lasted for? I'm convinced these machine shops are just anal about tolerances.
You could make a fortune. We have very few here and the wait time is so long cause they are overloaded
Did you guys use the same connecting rod
Sometimes you can go with a .10 or.20 rod bearing if the clearance is not fat enough.
No, sorry, you'd have really bad problems doing that!! Talk about a knock in your engine FFS!! ROFL!! That thing wouldn't last 2 minutes under load! LOL Hell, it probably wouldn't last the start up process!! LOL
How polished should the rod journal be? Mine still looks rough but I'm just trying to get this thing running and then get rid of it.
How did that go
@@mr3x972 I used 600 grit sandpaper and polished it really well, it has 4,600 miles since the fix and it has been fine.
Did you machine the crank
Good job dude...The key here is your tolerance on the bearing. you have passed stage 1 of 2. i would be satisfied when that bearing had done over 5,000 miles without any knocks. You could add ceramic coating to to engine to give the whole engine a new lease of life.
Reading other comments about how either some debris or unpolished parts on the crankshaft went through another set of bearings, do you think replacing the crankshaft at the same time would mitigate all of this and make it last somewhat indefinitely
Yes that would help, but Iâm sure there are particles elsewhere as well. Crankshaft possibly being one, but first thing that comes to mind is oil pump and the screen thatâs in there, especially since thatâs pre filter. Spinning a bearing and particles in your engine really messes stuff up!!
@@PostPros still better than a new engine though, probably
Replace crankshaft and connecting rod and replace bearings and it would be good as new again...
Good luck finding a crankshaft for this motor
.05 mm is .002 " good clearance
That sounds like what my cj7 engine is making on my channel lmao
Not sure if you are active atm but what did yâall start with âgrit wiseâ and what did yâall do with the cap?
Started with 1000grit finished 1500... sanded the cap a little toođ€ good luck!!
@@PostPros Iâm actually about to start tonight
I'm having that problem with my wife's Volvo s60 2.5t over rev
Aye man I have the EXACT same knock, only at 2-3k rpms like yall said. My rod bearing went bad for sure (ran out of oil.) is there any way you guys could help me? Wouldnât mind tipping you guys some money in exchange, just donât have anyone to guide me on my speed3 đ
Odds are extremely good that bearing'll run another 100k, consistent with the rest of the motor being good. Should really do all the mains while the pan's off. Just saying...
You would have to pull the engine to do the mains. You can change the main bearings on the caps but you wouldn't be able to replace the bearing on the engine because the transmission being bolted to the engine and bolted to the flywheel is going to keep the crank shaft from lowering. It would be wise to replace all the rod bearings
@@advancedanr you can spin them out, kind of a pain but doable. I've done it on an M62
There's no way in hell that thing even lasted 10k miles. You can't just replace a broken part and not fix the thing that broke it.
The video literally said that they went around a corner and oil starvation occurred.
And also ran low on oil, so nothing mechanically failed to ruin the bearing accept for user error running low on oil and taking a sharp turn
That is middle eastern engineering at its finest! To fix it right, pull the crankshaft and piston that's bad , replace the rod ,check the piston for damage, re machine the crankshaft.
it can hold this way too. Heck some BMWs require bearing change as preventive maintenance which is crazy imo. If you don't get them to knock and just change the bearings it will hold.
Or two stepped showing out. Ask me how i know. đ
I hope you at least put a new cap on the ended of the con rod..
Just drove 30 mins home on a spun bearing in my geo metro
Fingers crossed I can just replace bearing. But at least new engine is only $300 from Junkyard
update on the cars condition? going to get under my 98 crown vic to replace them either today or tomorrow. caught it really early and it sounds just like yours (not like others where its very prominent on startup and idle but a very early stage like yours). Hoping this'll last and would like to hear your reply man.
So we tried to replace them a couple times, but they kept spinning. I think the crank was just too bad of shape and was killing bearings.. idk.. It really depends on the engine and how bad it looks. Good luck with yours, hopefully caught it early enough!!đ€
@@PostPros Peter DeCarlo said it best, Rod cap gets oblonged and it will continue to knock rod bearings out. Only solution is to replace the rod then you won't have bearings spinning
Most of the time when people replace bearings they go with standard size and never look to see if undersize bearings were used, which would cause to much clearance and not enough crush fit.
Jerry Cantrell Jr here fixing engines.
I was wondering why he looked so familiar to me and you totally called it. If someone called me Jerry Cantrell Jr I would feel highly complimented. So I wonder does dude play guitar and sing?
my toyota camry 2001 , oil pressure light flashed made it a few months then went homeand now it soundsLIKE YOR CAR ,,, almost exactly/ maybe thee mechanics that looked or just listened to the engine are ALL CLAIMING DEEP ENGINE RUIN can be FULLOFIT
hey guys i have a lancer with a spun bearing, i changed the bearings ,but engine is super tight ( will start and idle with only a powerful battery) ,im attempting to properly sand and try it again ,this video gives me hope
update ,tried it ,works ,starts and idles smooth , but it depends on the extent of the damage
How long did it last? I'm about to run this repair on my Turbo MR2... haha.
it won't last long. don't try it!
If you flush it with mineral spirits it'll clean it
I have a 2006 Hyundai Sonata and my car started making this noise 268 miles ago. Had no idea what it was. Needless to say, I know now.
Lmao ive been driving my Veloster with this same issue for months now. I use additives to quiet down the engine. But now thay i know about this i will be replacomg my bearings next weekend
My 2008 Sonata started knocking bad and the engine stalled. When I saw that it was completely empty of oil, I filled it up. I then drove about 15 miles to get back home. Don't know what I will find, but my mechanic friend said he will come help me drop the pan next week. This just happened yesterday!
@@loudtwinkiesxd98 my Veloster is doing the same. Were you able to fix it through oil pan?
@@darrinstinson2890 yes. Repleaced it through oil pan. But doing so i also had to buy paste for the oil pan to put back in place.
Check oil pressure with a gauge? if you can push the piston down as it's in the descending stroke, that's the rod knock. should be no movement.
How much clearance did the rod have to the crank journal?
Apparently it's none ya!
@@Anarchy-Is-Liberty Yea I had to find out elsewhere!
It would be a whole lot easier to use the dipstick and top it up before it sucks air in the pickup don't you think?
What would happen if you dont buff the crank journal and just replace the rod bearing?
That could work, but sanding/buffing just insures you that itâs smooth and not any high spots on the surface!
@@PostPros I only ask because I believe my buick has a spun bearing(s) and I dont have the time or money to machine my crankshaft, let alone, replace it
No very bad need to be smooth polish look any imperfections will clean of oil film and scrape badly and u will be back to zero or worse
It will go out again. the rod journal is out of round.
Just cut a strip of sandpaper and put it around it, then wrap a shoelace around that twice, and you can pull each end of the shoe string to sand it nicely! Cheap!
You haven't driven it long enough... It may last 1000 miles if that...
Anytime you spin a rod bearing, you damage the journal of the crankshaft and the connecting rod bore...
Short of having the rod resized there is no real way to fix the rod...
Another thing is that the journal surface is no longer square without having it turned undersized.
If only I could just get someone to do this for me. No shop will do it, they just want to put a whole brand new engine in.
Because it likely won't last 1000 miles and you'll lose all your money and be bringing it back to their shop complaining. So of course no shop is going to do this. It's just a wild experiment that only has a small chance of lasting.
@@calholli what you donât know is I spent $30k on a completely fully built brand new 1100 hp engine. I understand certain components would need replacing but no shops near me that do anything sort of engine work will work on a Subaru and Iâm not throwing away a perfectly good $20,000 engine when all it needs is some bearings and a few other parts.
@@zokusharuuku1091 I hear you... It's worth a try. But you're not addressing what caused it in the first place... It's like stepping on a nail and it stabs through your shoe and now there's blood on your sock. You can change to new socks again, but as soon as you stick your foot back in that shoe and take another step, that nail is just going to stab your foot again. This engine didn't fail because of bad socks-- it failed because it has a damn nail sticking through it somehow. I hope you understand the analogy.
Just read the description of this video-- he even says that it didn't work for long.
You we suppose to take it to machine shop. Get it machined and get correct bearings.
Heat is your engines enemy. Go with a synthetic blend and be sure to flush ALL THE OIL OUT. Replace the bearings, making sure there are no pocks or pits.
Use a spot of trans fluid to hold in place when reassembling. Go with a quality oil filter and good oil and some Lucas as rhe last quart added.
Be sure the cooling sys is top . Fan relay working, and flush cooling sys , refill with new coolant . Per Auto make.
Don't go ape shit for a few hundred miles. And it should hold for a while.
Is the car still holding up bro? Really appreciate the video it helped me out
Our crank was too far gone and kept eating up bearingsđŹ
Just all depends on how everything is looking in theređ§
Decent video but when I needed a clear concise number on the plasti gauge you mumbled something unclear like .5 at one time and .05 another time. I think I understood it had to be less than .1 (1/10th of an inch) but that sounds like a very large gap. Did you mean .01? Anyway - post that detail under explanation. I got the concept - kill engine and follow your procedure. We've got a 4.3 Chevy with a rod knock but hasn't spun - and not driving but will drive it off trailer to position for this procedure if we can figure out if we can get the oil pan off but crossmember is in the way. At least front wheel drive cars oil pans seem to be more easily removable.
is this the way to fix a slung rod ?
Possibly, it just all depends on how it looks..
Good luck!!đ§âïž
Did you replace the connecting rod?
For that the headers have to come off, because connecting rods sit on top of the crankshaft
I sure wished you lived around here
Anybody know if this will work for a spun brg on a frs/brz/86?
It all depends on the damage the spun bearing made
Did she hold up?
No, we ended up changing the engine. Crank was too badly worn out.
When did jesse eisenberg start making CZcams videos, and stopped making movies?

Update on the bearing ? Good job guys
Bearing kept spinning after we replaced it, the crankshaft was in too bad of shape. Worth a try tho!!đ€đ
@@PostPros how long did it last?
Couple months, then started hearing it againââ
That was not looking great. It is likely going to take about 10-25k and/or a bunch of cold starts to go bad again... The damage occurs primarily on cold starts before oil pressure builds to lube the bearing. It'll definitely go bad again though even if you keep the proper oil level. I had a Volvo S40 that I nursed along in the same way changing the bearing every 25k or so... Mine didn't look as bad as yours but mine wasn't pretty either. I drove that thing hard in the canyons... was not gentle with it AT ALL after the repair. It held up enough that I didn't mind changing the bearing from time to time. It's a good temporary fix if you don't have a line on a good replacement engine.
A spun bearing primarily comes from oil starvation whether it be a cold start, run out of oil or failed oil pump...
đ
While weâre at it, could also be due to clogged oil passage(s)âŠ
Can you please tell me the torqued specs you used I'm now doing this to the same car and can't find the torque specs to it someone please help with this
Iâm a delivery driver and I went about 4 months with it knocking exactly like this. You think I can just polish the crank? Lol
Cross your fingers!!đ§đ§đ
I drove my town and country for a week 75 miles twice a day on the freeway, changed the bearings, still was knocking... disappointed I drove it like that for two weeks, same drive 75 miles twice a day, figured to change the bearings just to bandaid it till I could get a new motor, changed em and no more knock. Iâve now driven it 10k miles still no knock. So I guess I might not have had it seated perfect when I did it the first time.
That wasnt spun. That was just minor knock.
You can get away with cleaning up crank but if you don't change rod it won't work .PS ROD GETS EGG SHAPED Must replace or repair rod
Seriously.. music at the end of your video What is that? I can not find it using recognition software. Please!!!!!

clueless kids buffing a crank shaft with a spun bearing.. mercy
Still going good?
It ran for a while but the crank was kinda torn up and kept eating bearings. It was definitely worth a try!
@@PostPros what's a while, a few days or weeks?
Could you have buffed the crank more?
Dust in a bus howâs it running now still good? Is the knock still gone away? Iâm about to do this to my engine 1 question, did you have to take timing chain off or was you able to do all this without touching it?
Stickydicky well it ran good for a while but the knock came back. Replaced it again and itâs running fine. I think there was some crap in the oil passage ways because only the center of the bearing had wear on it which is right where the oil comes out. Weâll see how long it lasts this time!! Didnât have to mess with the chain at all. Just took the oil pan off and was able to get to the rods. Good luck!!
dustibus cool man glad to know itâs atleast still running , I knew the knock would eventually come back but itâs worth it in my eyes to stay on the road weâre you able to use the same rod bearings(new ofcourse) or did you have to go up a size or have custom bearings made?
Stickydicky no just stock bearing, I think it would last a while. But I think a chunk got in the oil passage and got to the bearing. Itâs turbocharged too and doesnât have an easy life, so if your easy on it, itâll probably last a lot longer!
dustibus awesome man thanks for the quick reply
dustibus sorry bro one more question now that I think of it ,, how would you go about cleaning the oil passage hole the easiest most effective way
So how long did it last?

@@PostPros how long did it last?
@@PostPros More than likely it was the rods big end that was causing the spinning. You could also take a punch and punch the main bearing journal in the engine to help hold the bearing but very very slightly.
The problem is that Its a VW.
99.999999999% of the time, a spun bearing is a done deal, it's time to replace the crank/rod(s) whatever the spun bearing was connected to! If it's a main bearing, you can only pray to the none existent god in the sky that it didn't F up your engine block beyond use as well!! Most of the time it will overheat your crank beyond repair too! At that point, hopefully you have very good mechanical skills and can do the repairs on your own or you better get out the pocket book, because it's going to cost you big time!
If your rod starts knockin', you better start shoppin'!!
send it until it blows. luckily the junkyard has plenty of engines for cheap
I got tired of looking at his mug!!!
It must be nice to be ignorant enough to think you can get away with a fix like this. Having resized dozens of spun conrods and blocks I know this isn't going to last long, not to mention what will happen when they snap the crankshaft.
