Unreal. I have never seen this before. Must be a bad rubber seal in side the oil pump. It is definitely not coming from the front main seal. Thankfully this should be an easy fix.


There is an o-ring that could have gone bad.

If you don't want to drain all the oil, I would crack the oil pump bolts loose, and let it drain into a pan, then top off with fresh oil.


More than tread lightly. Leave it like you were never there, nor anyone else.
