Default Re: Main bearing oil leak

Installing a seal in the rear main requires modification of the crankshaft to install. I hope you didn't try and fit a seal on a crank that did not have the slinger machined off? If this is a case were you installed the seal without removing the slinger, I think you are going to have to pull the engine and fix.


Re; Oil is controlled by bearing clearance only. The slinger is at the back and it is there to prevent oil flowing out the back with the tube acting as a drain.
