Re: Rubber Rear Main Seal
One thing I'm wondering about:
For the rope seal to be lubricated, the V6 crankshaft has angled serrations cut in the crankshaft. I added a picture that I had, it might be difficult to see because of the assembly lube.
Do these serrations interfere with the sealing capability of the lip seal?
Should one have to regrind the seal surface on the crank for the seal to work properly?
