ENGINE KNOCKING NOISE DIAGNOSE AND FIX

ENGINE KNOCKING NOISE DIAGNOSE AND TEMPORARY FIX

[Onry]

FINALLY! An engine noise video that actually has a noise in it instead of 10 mins of talking about a noise...

I can't give this video enough likes... perfect amount of helpful info, from actually running the car with the knock, to showing how the rod bearings were wore out. Thank you

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.

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.

1 of the most useful videos on YouTube

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!!!👍😀

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.

screw the haters the video helps a lot

Man that this the most terrifying noise I have ever heard in my life. Breaks my heart and wallet

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.

Mate, get long screwdriver and put rubber end to ear and put other end on motor, move around until U find where sound coming from.

This is a great video! My 2003 Dodge Caravan 3.3 L engine, makes the exact same noise. I am mechanically inclined to do the job. Thank you! You make it look easy.

[mgreen]

would have really been helpful if you showed the steps for the installation of the new bearings, but informative helpful video.

I just replaced a bearing and it's doing great

[checkmatenate]

Probably the best rod knock videos out there. Nice job 👍🏼

[DashenShivambu]

My car have the same noise, I will try to fix it myself. Thank you very much

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.
