Just measured connecting rod bearing clearance with plastigage and found that the clearance is beyond the "allowable .022-.069mm (.00086-.0027inch)". How do I find out which type of rod bearings I need to get back within the allowable range? I understand that going to a machine shop to have the crankshaft machined properly is the correct way to go. But it is only my first car and I just want to put an end to the rod knock it has.
I gave this answer here : Oversize rod bearings question
A decent machine shop should machine the crank pins and provide the correct bearings as part of the job.
Did you measure the journal in the car? If so, not good enough. It can be tapered and/or out of round.
The bearing is likely a symptom not the cause. A new bearing will be a short term cure at best. And the crank situation will just get worse. TomO
