Hi I currently have to motor out and apart. Would like to know what the oil clearance spec is for Main Bearings Mark 3, Also Connecting Rod Bearings Mark 1. ConRod bearing are worn out bad but crank looks good, don't see scuffs or deep groves/scratches. Feels smooth. I am going to rebuild engine for the second time. First time I went off of the bearing sizes that the engine had. Bad on my end to trust the bearing sizes PO put in. Used car for 2 years until rear main seal failed and decided to pull engine out and go over everything again. Found ConRod Bearings worn. This time I will rebuild engine to spec and just in case crank is damaged, although looks fine , I will get it inspected by my local machine shop. In the event crank needs to be grind down I would like to know oil clearance specs to give to machine shop. Don't want to pull motor out for a very long time. Thank you for your time and help!
