Need best method for no leaks at rearmain and oil pan

i toss the oil pan gaskets and end seals right in the garbage can. a caulk gun tube of black rtv will seal everything up and it'll never leak. done hundreds of engines this way.

That is very good to hear. I have a fabricated aluminum pan from Charlie's Oil Pans and its not designed to accept gaskets. So I did exactly as above. Fingers crossed it works on first fire-up as the bolts are a PITA to get to (they're inside the pan).
