I had the same problem, it would get on my serpentine belt and a little on the ground. I replaced the two seals that mount the oil heat exchanger to the oil filter assembly, and also the seal on the little cover below on the timing cover. It is an access point to gallerys or for oil pressure. It, or the upper seals will slowly leak down the front of the engine and make you think the oil filter cap is the culprit. This cured my only leak and kept things cleaner all around. Hope this helps. E

Make sure the oil filter is tight and not the source of the leak.
