If it drips when parked, you should  be able to see where it drips FROM. 
That narrows down the possibilities a lot.

How much oil are you seeing? Does it leave a spot on the floor the next 
morning, or a puddle?

There is a drilling in the case, between the crank seal and the #1 main 
bearing, that's at a rather odd angle. It's possible that it was carefully thought 
out so that the crank rotation would tend to pump oil out that hole and back 
into the sump.
