I have a 421 with 455 crank bored 60 over with 670 heads and flat top pistons.
When idling, the rear main seal does not leak when I drive it, and oil leaks out of the seal.
I do have a new PCV in the pan going into back of manifold.
Has anyone had same problem and corrected the problem?
I have already changed the rear main seal six times.
