Noticed that after I towed my boat I had a wet spot in the driveway. Crawled under and can't find were it's coming from. This happened last year and the dealership said it was the crankcase sensor. Replaced it stopped, now doing it again. Oil seem to be running down above the starter any ideas? Pulled the bell housing cover off and no oil on the rear main seal.

Some possibilities:

Valve cover leak at the back on that side.
Intake manifold leak at the rear on that side.
Oil sending unit.
