Love how u ddnt take the whole engine apart to do a simple fix im gonna check my rides now i have 2 vehicles with the same knock? THANK U SO MUCH FOR THE MECHANIC VIDEO!!!👍😀

[@MollydogRadar]

Had this happen to my 94 Chevy Z71. 350 engine. It started when I pulled our 5th wheel to Blyth for Dove season. I lived in Hesperia, 170 miles away. The knock got real bad going up Cajon Pass, on the way home. I pulled the oil pan the next day, pulled off the #1 rod cap. The bearing was trashed, but the crank was fine. I replaced all the rod bearings with no further issues. The truck is still on the road today with over 431,000 miles on it, with the same bearings I put in it, purchased from NAPA auto parts.

[@DIY_PROFESSIONAL]

Happy to hear that this procedure worked.

[@davidellis279]

Your a very lucky person to get away with just replacing the rod bearings especially after such a high mileage,I think at the very least I would have replaced the main bearings as well just to improve oil pressure,it’s not often you can get away with what you did at least not for long,you have more faith than me doing this.

[@editmystery]

Lots of things you guys didn't even try. First of all you can't just replace only one and call it a day, you have to replace all and sand it a little to smoothen it.

[@garylangley4502]

When repairing something like this, you have to be a bit of a detective. Ask yourself, "What would cause this?" The 2 answers are 1) not enough lubrication or 2) excessive engine speed. If there is not enough lubrication, take a look at the condition of the other rod bearings, and the main bearings. If something like a defective oil pump is the cause, then all of the bearings will have some damage. If it is just the one bearing, then I would suspect a clogged oil passage. The rod bearings are oiled by a passage in the crankshaft from one of the main bearings, in this engine probably the front one,. You can clean the passage in the crankshaft, and check to see if the passage from the block to the main bearing is clogged, which would also cause damage to the main bearing. Years ago, there was a service available where the journal could be ground in the car by removing the oil pan, and replacing the starter motor with a large electric motor. Various grinding stones would then be used to grind the journal round again. The engine would then be cleaned of the metal shavings, and the rod bearing replaced with a thicker one. I don't know if this is available now, as this is a very old way of repairing a crankshaft. Another possible repair is to buy a used crankshaft that is still in reasonably good condition, and replace the damaged one in the car. It can be a lot of work, but if a person does not have enough money for a rebuild, then this is a possibility. Also consider replacing the engine with a good used one from a wrecked car. These are some of the experiences I have had over many years repairing my own cars and friend's cars. Best wishes to you.

[@princechigozie7194]

Quite a word there, you said it all.. the point you said a clogged, answered it all. The oil galleries sometimes blocked either due to bad oil or lack of servicing as on when due, presenting am battling same issue on a 400 series Perkins generator, infact the number one Piston had to burst the engine block, I have to get another wreck good engine block, change crankshaft, Piston, metal and main bearing.. am at final stage of rounding up, the Gen will soon be use again

[@DIY_PROFESSIONAL]

[@Musique-zz1dy]

if no oil, it was a problem of oil circulation. when you putted off the old piece, you noticed the absence of oil... you should have concluded the oil circulation was blocked on this piece... you should have pushed with air or with anything through the oil hole to disblock it... since the oil circuit was not cleaned there, the new piece was not oiled... so it soon came to ashes like the other one and the sound came back.

[@MrCuckoobox]

The crank shaft need to be resurfaced or replaced........I have seen a couple of people try (and been successful) to the polish the crank on the one crankpin journal for the connecting rod while it is still in the engine. It is not easy and it depends on the damage and how well it is polished and then how well the bearings are matched. If it is not done well it will end destroy the engine in the end. That bearing "spun" because of a lack of lubrication. You can tell by how dirty the engine is that oil has not been changed on a regular basis - that caused the engine failure. Moral of the story: Change your oil or you will end up changing your engine.

[@DIY_PROFESSIONAL]

I agree with you, but this is just an experimental process as I mentioned in the video. Very nice comment , thanks 😊

[@MrCuckoobox]

@@DIY_PROFESSIONAL Understood.......I would have liked to see you polish the crankpin journal before replacing the bearing there......It still may have failed. Sometimes "the scoring" that is on the journal is just bearing material that needs to be removed. This (below) can be done with the crank in the block but it makes it more difficult. kzbin.info/www/bejne/iH3FZ5WPqs-YatU&pbjreload=101

[@1peanut]

spun bearing. usually caused from lack of oil. at some point it probably had oil leak and ran it to low on oil in the past.

[@AlfredRevis]

I just did this job yesterday on my 07 grand prix I put a std bearing in but it still had a little play in it. I wanted to know if there is a little thicker bearing I can get. This is a great video keep help thanks

[@vibrantalien430]

If Std bearing have the play, try the 10 size bearing, if that also have the play use 20. When you go for 20 remember it's the final point of the crankshaft. 20 can't hold load for too long.

[@gregorymalchuk272]

Use green or blue loctite between the bearing shell and the rod/cap. The bearing will never spin again and it will provide some thickness. This is an actual racetrack practice and it works.

[@michaelmyers3892]

Have a 2002 Subaru outback with a 2.0 4 cylinder, and we're fixing to drop the crankshaft out clean it up and put all new rod and bearings in it this way the bottom in is nice and fresh it only has a mild knock but we all know sooner or later that's going to get worse and catastrophic might as well get on it now and fix it before it gets worse

[@XJaysznX]

Did yall like not watch the end of the video he legit said it didn’t last long and that he doesn’t recommend

[@bdb3350]

I build engines part time; 5-6 a year. The instant he found glitter (its pulverized metal) in the oil pan the engine is junk; he should have put the pan back on and look for a new motor. Remember there is several times more in the rest of the engine and it is impossible to get even a fraction of it without removing, tearing down, and cleaning the block, heads, oil passages and every internal engine part. Otherwise when you get done repalcing the trashed bearing you start te car and pump pulverized metal i to the new bearings. Not to mention 99.9% of the time The crank MUST be machined.

[@Ownsterx]

The engine is fucked, he knows it's fucked, this will at least get a little more life out of it.

[@bdb3350]

@@Ownsterx Not much life. The best case scenario installing a bearing on a scored journal will last only give you 5-10 minutes. Then you have it towed home, your doing an engine transplant anyway.

[@DL101ca]

@@Ownsterx on a scored crank he will have no oil film to support the pressures generated when the engine is running, so instant destruction of the new bearing surface. He wasted a lot of time and some money for no gain.

I did all this to my ford focus and had to fit new undersized bearings (thicker) and added the Lucas oil thickener...like the guy said.. the engine didn't turn over to easy but it wore its self in sufficiently..still going a year on

[@DIY_PROFESSIONAL]

That is great. Thanks for sharing your experience.

@@LeftInTheEnd ...the main journal was pretty much egg shaped to 0.5 of a mm.. With the crank shaft still in the engine.. sanding it down would be impossibly difficult..I just fitted undersized bearings to make the knocking less apparent....the really thick oil helps stop the metal against metal problem of an egg shaped journal...good luck

[@camowilo]

Emery cloth to hone the surfaces is a good all contact surfaces to prevent it spinning again and probably should replace the oil pickup too as it's probably clogged with bearing material

[@GunPlayBreezy]

I just bought a 01 Ram 1500 SLT 5.2 Oil pan has left the chat on me after hearing knocking from under on a drive I will take oil pan off tomorrow to see as it is night time now but I’m mainly asking what all should I replace do I have to lift engine just to get pan off

[@robertrpenny]

That ain't no lifter dude. Sounds like a con rod. Looks like con rod. Needs crank turned, oil pump and over size bearings. Can't cheap out on that one as you discovered.

Good video. This is happening to my 06 Infiniti M35. How much does a repair like this usually cost?

[@WasabiBoyNZ]

Sad to see you do this. I'm surprised the engine even turned over after you bolted the end cap back on. No micro measurement to make sure it's a correct fit, and the journal on the crankshaft was toast mate. Needed a regrind of all the journals and some paired oversized shells (bearings). An engine builder would cry watching this effort. I feel for the new owner! However, good effort on the video even shows you what NOT to do!

[@DIY_PROFESSIONAL]

Thanks for the comment . I understand your concern but if you watch the hole video you will understand that this was an experimental repair and the fact that this didn't last for too long. And don't worry about the new owner because the car unfortunately was uneconomical to repair properly and ended up as a donor car for others. I appreciate that you cares about others. God bless you!

[@pigg20021]

The cheapest fix to get this baby back on the road is a used engine. It will cost at least $1500 in parts and machining to get this engine back in spec. Rod bearing is major engine failure. He lucky if the engine starts and stay running 10 minutes with his solution.

[@brustar5152]

No kidding! And even if it runs; five minutes away from that shop and anything over 2500 RPM it's gonna start knocking all over again, even if that rod shell bearing doesn't spin again, although it almost certainly will ! Wasted time spent making a half azzed repair that has a half-life measured in minutes.

I knew before the end that the end result wouldn't be good. As soon as I saw the spun bearing, I knew you should have replaced the connecting rod. More than likely, it just spun again.

[@SonnetGomes]

How did this happen to begin with? Could it be any holes were clogged up and no oil is reaching to the bearing? Either ways...great video. I hope this never happens to anyone's vehicle. I am suspecting this happened due to lack of oil on that specific piston.

[@DIY_PROFESSIONAL]

My opinion is because something blocked the access off oil in that area for some reason...either because of lack of oil in the engine or maybe some clogged holes like you said ...but also could be because of weak oil pump or just bad quality oil...

The barn job brothers strike again!!! The proper way to do that job was to completely disassemble the engine, resurface the cylinders , resurface the crank replace the connecting rod with the spun bearing throughly inspect the others, do a complete valve job since you have the head off already. Clean the entire block to remove the metal particles in the oil galleries fit new rings on the pistons and reassemble the engine.

Replacing the damaged parts should be enough. But the fastest way is to replace it with a good engine. You will need loads of gaskets and seals ones you tear it down.

[@shawnwalters9318]

Spun the bearing and when that happens that little oil port hole in the bearings misalign and close off. Then the crank journal REALLY starves on oil and it ovals off the rod journal on the crankshaft. Sometimes you can get lucky and only change the rod bearings and your ok. But it depends on how long you run the vehicle after it starts knocking

Did you replace all the rod bearings when you dropped the oil pan or just the one bad one? I'm curios if you only changed one if the returned knocking was from the others failing or the fact you didn't replace the rod, bottom hat and polish the crank.

[@DIY_PROFESSIONAL]

I replaced just the one was making noise from what I remember...

[@macariohernandez72]

Thank you for being honest

[@murtazasier5978]

My car (camry 2018 Se) at times has a knocking noise when I stop at a light or when the car is is D mode.The knocking disappear when I put it in N. any advice on what the problem might be

[@DIY_PROFESSIONAL]

I am not an expert in automatic gearboxes but from what you tell looks like you have a problem with the gearbox.

[@adamnorton4048]

I have the same issue with my 2018 sonata.

[@philjerome9795]

Might be an oil pressure problem. Hook up an external pressure gage.

[@mikecarey8183]

Oil pump was probably original isue

[@stephencrabb5123]

Can you change the bearings without grinding the crankshaft?

[@DIY_PROFESSIONAL]

Yes , but the result may not be ideal. If no damage was made to the crankshaft then your good.

[@marcusmarrs]

If you have a rod as loose as this one, not only can you NOT avoid regrinding the crankshaft, there’s a good chance the crank wear is past the point of grinding. I’ve seen many worn way past .030 rendering the crank junk.

[@mackt575]

So with all that being said, how much does this cost on average and at this point?

[@bubbles8491]

With knock being that loud and rod bearing that bad your "quick fix" would never have worked. The only cheap way to fix this problem is to replace the engine as a whole. Since there were metal shavings already running through the whole engine it would make other parts fail.

[@DIY_PROFESSIONAL]

Unfortunately, yes, you're right. But the whole purpose of this was just an experimental method to see if it works and for how long if it does... Thanks for your input. Very helpful.

[@EverydayProjects]

@@DIY_PROFESSIONAL I would have said the same thing, that the metal is now throughout the engine, but sometimes a guy has only so much money and just has to do a fix that will get him through several weeks/months. If you change the bearing, flush the engine out as good as you can. Run about 1 litre of kerosene in new engine oil and idle the engine until up to temperature , then drain the oil and refill. A couple of flushes with kerosene in the oil and the engine warmed up slow without revving can clear a lot of debris. Don't forget to install a new oil filter once the flushing is done. You will get most of the small metal particles out and you may be able to drive the engine for quite a long time. Good luck!

Seat leon 2001 1.9Tdi here, changed the oil and oil filter a months ago, and like 3-4 days ago i started hearing that knock sound but only when i shift (so like if i put the engine on neutral or hold down the clutch the sound is there) but when i accelerate it goes away, and i don't think it's there when i engine break either, it's a loud engine so it may cover it up but u don't think so. What could this be?

[@chriscusick6890]

Piston slap maybe

[@richwalker8825]

If you had cleaned up the crank it would of been fine

[@ScratchNowWithJeremy]

How do I clean the crank? 1998 Mercury Grand Marquis LS making this noise, not as badly yet

[@richwalker8825]

@ScratchNowWithJeremy use the shoe lace method with different crit sandpaper

[@show316316]

Don't use Red RTV as gasket on any oil pan and trans oil pan. It cann't block the oil coming out! I did 4 times on the Trans oil pan and still leak. While change to use Black RTV, no more leakage

[@CodyDoesIt]

16 Elantra Gt manual I was considering doing the same thing just to sell it. But if I didn't how reliable would it be like this would you say?

[@tr199yninja]

How long did this fix last?

[@DIY_PROFESSIONAL]

About 2 weeks.

[@tr199yninja]

@Ioan-Bogdan Feher Damn. My car is running for at least 2 years with a knock. Just changed the bearings to the most undersized there is but there's still play. Wonder if this is worth a try or would it make it worst.

[@reivaxcruz8324]

You dont have to open on top .. did you only take bearing of and replace on the oil pan? ..

[@wootang951]

Honestly thaks for this, saves me the time and effort
