I ditto John's comments. I used the Permatex Ultra-Gray RTV on the mounting
plate, both sides, and I also have a very small, but annoying oil leak. No
real volume of oil, but enough to drip down the radiator in 2 spots at some
time. Maybe 1/2 tablespoon of oil in 6 hours.

Rather than lock washers, wouldn't it make more sense to use drilled
head bolts and safety them together in groups of 2 or 3?
I'd agree with the safety wire. I've noticed that my sump bolts (with lock
washers) want to undo themselves. I've tightened them twice in 8 hrs. About
a 1/2 turn each time. I'll be safety wiring them when I redo the sump /
mount plate / engine join... with gaskets this time.

When you do the pan gasket job you may help avoid further leaks by using
a small punch to lightly stipple both mating surfaces on about 1/2"
centers in a random pattern. This keeps the gasket and/or RTV from
"walking" later on and causing those extremely annoying seepages.
