<VV> oil leaks

I've not been following the thread too well, but it does seem to me that the
original question indicated that leakage was there prior to the engine being
run.  I would be more suspect of the rocker cover gasket and/or a push rod
tube than a top cover leak.  Of course, if the car was driven and then
parked over the "clean" spot where the leakage was detected... that COULD be
the top cover, since it would take a while for the drips from the top to
make it all the way down the block and onto the floor.
