1 of the most useful videos on KZbin This happened on my Opel Astra F c16se, 1st there was that engine knocking sound then I opened the top cover & noticed there was no oil reaching the hydraulic lifters then changed the 1 camshaft 2 oil 3 oil filter 4 head gasket It continued & was clueless untill I bumped into this video For sure my no1 piston was shacking and had no even a piece of bearing left. Will update soon, hope the parts I need now will get them by Tuesday. Thanks a ton man.

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.

[@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

My mild custom 1998 Oldsmobile Intrigue 3800 Series II started a bearing rod knock as yours did - I changed oil to Synthetic and STP synthetic oil additive not traditional oil to nurse it, and it grew quiet but I'll keep my foot out of it. The main problem was standard recommended oil, it all started using passing gear oil sloshed a bearing dry.

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

[@brianseiferth2681]

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.

BJ if you can hear it coming from the bottom of the engine it's going to be a rod bearing. The crankshaft sits inside the oil pan at the bottom of the engine. The lifters are at the very top of the engine trust me and save yourself some time you'll want to replace the whole engine.

[@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.

[@sirrichardrichard5655]

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

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

I have the same issue started yesterday and I'm looking for solutions but its not a desperate process it's more of a learning experience. Would I have to rebuild the engine or just replace the damaged parts?

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. Also bear in mind that an engine is got couple of screws and parts that you will need to replace before reassembled. Good luck and Hope that helps

What could this be?

[@chriscusick6890]

Piston slap maybe

[@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

[@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.

[@Manny30004]

It’s a rod knock or bearings if you founds metals particles you do need a new engine or you could rebuild the engine

[@DIY_PROFESSIONAL]

Hi. The most safer way to resolve this issue is to replace the engine . The metal shavings even if you change worn-out parts still can be stuck somewhere and at some point will come back in places you don't want. But if there is just a little amount off metal residual, and there are minimal damages, and you have time to strip the engine and recon/replace damaged parts there are good chances to be still good but you have to find out why engine was starving of oil in the first place. Good luck and hope this helps.
