Re: oil leak rear main
Good Day eric...Your rear main bearing should have a clearance of 0.015 to perhaps 0.025 so oil can support the bearing. If more, the rear main will leak. You can use Plastigsage to check the clearance...you should have some shims between the block and the bearing cap that are used to adjust the clearance. If you have too much clearance and no shims...then the engine is in need of a rebuilding...if no shims and the clearance really is 0.001 then you could/can use some very thin shims to open it up a bit. Good luck. Ernie in Arizona
