Main Bearing Clearance

Rodzilla said
This I agree with, but it would equal a .002" difference in the OD of the crank journal and the ID of the bearing. So is that how it works? Or do you need a difference of .004" to get a clearance of .002"?

If your looking for .002 thats what the plastigage should read and that will give you the clearance you need you don't multiply the reading by2
