Found the source of the small oil leak we found when we moved cars in preparation of attending the Fall Rally. Turns out the source was the drain screw on the oil pan. Must have incorrectly installed the crush washer when I did an oil change earlier this year. So I removed the drain screw, drained the oil, cleaned the drain screw & put a new crusher washer on it in the correct orientation, re-installed the drain screw & tightened to required 30 Nm. I then slowly poured the oil back into the engine using the oil fill port. (Note: I didn't want to remove the oil filter for pouring the oil back into the engine. No need to waste an oil filter.) Started Coupe & checked for leaks. None found, so I started gathering up tools & putting stuff away.
