Any special tricks to installing a rear main seal?

[Securis411]

As I said in another thread, I got this oil leak. We worked it over for a day and a half. Mainly wrestling with seized up exhaust bolts. That's what took the longest to get apart and back together. All new workings go in and still there's this oil leak. New pan gasket and new rear main seal. But it still leaks and we're thinking the rear main seal isn't right.

I'm thinking we should do an extensive look at the valve covers before taking anything off. It could be from upon high. It could. Still, is there any special tricks that might help create the best seal possible?

So that brings up the question of what a worn crankshaft looks/feels like. I'm by no means a mechanical type of person. What will I be looking at to determine if a Speedi Sleeve us what I'll be needing? And will the regular ole parts house have this part?
