I've torn the NA engine down on my wife's '90 notch. The engine has been gone through before by someone. When measuring the mains I get a diameter of 2.183, the specs I have are for the minimum to be 2.3982, that's a difference of .2152 almost a quarter of an inch! The rods measure 2.018 with a spec of 2.0465. That's even worse at .447, close to a half inch! The strange part is I Plastigauged the clearance with the old bearing and got .004 clearance. Clearance should be .0008 - .0026 on the mains and .0008 - .0015 on the rods. Clearance is out of spec but not horribly bad. I've measured thses several times both with a Starrett mike and a digital caliper and gotten the same results. Has someone put a different crank in here? Did some other year 2.3 use a crank with specs close to these?
