So, the excess oil drips out. This is not a problem in Nebraska or Kansas, but it can play havoc in steep hills/mountain areas of our country. Try draining a little oil until you reach the halfway mark and then see if the leaking continues. There will still be residual oil back there from earlier steep incline parking, so don't expect the problem to go away immediately.

Interesting, as a newbie Model A owner of 5 months, I changed my oil and naturally filled the car up to the "F" level. I noticed about a week or so later a stream of oil coming out the back of the pan.... My Driveway is about 10°... (on it's own after I turned the car off a 2-3 hours later the oil was.... just about 1/2 between L and F and that's where I keep it.. So far not more oil leaks (BIG STREAMS )... and that was in April..
