ok... one of my rod bearings went out and i replaced all of them...even my main bearings... but the rod is still knocking. so i am starting out with a .03 or 30,000ths over bearing... but the main thing is all this happened when i changed my oil and oil filter...then the oil leaked out of the filter seal some how... so i figured i lost oil pressure and thats how the bearing spun out i guess... also when i drive the car and the engine is heated up... the car still seems to idle all the way down when i take it out of gear... can someone please tell me what could of went wrong? all the help is needed..

well if the bearing spun then you need to do more work then just taking it apart and switching out the bearings. The rod most likely needs to be resized, and the crank journal should be reground for an oversized bearing.

On top of all that the piston could have bent a valve as well if the bearing was sloppy enough to allow it to travel that high in the cylinder.


Can you be more specific on what you did while changing hte bearings? Was the motor completely torn down and cleaned?

I have a sound clatter i think its the main rod bearing letting go, its not the valves, any suggestions ?

check your oil pressure sending unit on the back of the head...it might be bad...i had a similiar porblem before but the motor blew shortly after...a rod pierce the block
