When I had the pan off I looked at the rear MAIN seal, and it was fine. The rear oil pan seal was mangled up pretty bad, so I installed a new one. But, I think i over tightened the pan and squeezed the seal out.

Is there any way to install a new rear oil pan seal without pulling the pan?

Thanks for the help.
