Is there any way to PERMAMENTLY eliminate rear main oil leaks?

Gus Wilson had words to say on that subject.

For awhile there was a special anti-leak rear main bearing offered for the Slant-6. Had two diagonal grooves cut into the bearing surface. As far as I know it's been unavailable for a long time, but—again—it should be possible to get a reasonably dry rear main seal with careful attention to parts selection and install technique, and without any special rear main bearing.

Reading that actually jiggled a few brain cells . That was actually a real occurrence, but I don't think it was Mopar. But, anyway, I didn't think of this because of it being a new engine.
Is the PCV system connected and working properly. That used to be a common problem with slants.
