Come on Tom, fess up. You were a young man then and could get into the
contortions needed to check the rod bearings :)
When I dropped my pan this summer it wasn't so hard but it had been on only
for a few months. The biggest problem was how to remove the last bolt w/o
getting hit on the head with the pan. Then when it was off and I was looking
to check for damage oil kept dripping on my face. I looked like a Dalmation
by the time I was finished.
One other problem when switching to detergent oil is that oil passages can
easily become clogged when years of accumulation let go.
When I removed the pan on my original engine last weekend I had the problems
you described and wacking it did no good. I ended up using a large bladed
screw driver to drive between the pan and the gasket to pry them slighlty
apart. I don't like to do it like that but it wouldn't come off otherwise
and you need to be careful not to gouge the mating surfaces as you know.
