I have thought about the various mating surfaces leaking, but didn't really know a good way to fix the problem. Do the pins just pull out of the rear main and press back in? Could I use a piece of glass to wet sand on?

They make a slid hammer style tool for pulling dowel pins. Snap-On makes one.
The dowel pins do go back in. Never used glass. May be fine. I used 280 grit paper, then 400.
I think you have something screwy going on to have oil pressure like you discribed. I've never had one do that.
