Well I drained and dropped the pan tonight. Inspected the gasket I put in a few weeks ago - it's a flexible, black material, kind of like hard rubber, very thin. (not much thicker than the rubber of a bicycle tire tube). Inspected the pan and found a low spot on the bolting rim that is (what a surprise) right where I was seeing most of the seeping. I lightly ball peened the rim in that area and got it to look a little better with a straight edge. lightly peened some of the bolt holes that were slightly mushroomed, too. Then installed pan with my new, reusable, much thicker, ATP gasket. Also, the holes have grommets - on the old gasket the bolts fit in the holes very tight, I'm wondering if that could be some of my problem, too. (gasket twisted a little as I was tightening bolts??) Anyway, tomorrow I will fill it and test drive and hope for the best! Thanks for the help.

Ah yes....the cheesy inner tube gasket...
Never seen one of those things actually work...too thin, and mooshy to seal anything. Add in a slightly disfigured pan surface, and you have a recipe for leakage.
The new gasket should fix it up nicely.
