I had two small pieces of slag on my oilpan flange that were not caught by the manufacturer of my 502. Didnt leak a drop for two years then started to get oil in the bilge. thought it was my drain wip but it was the pan gasket. I pulled the motor to fix it. clean everything up and go for a ride and you will find the leak.
