Hi guys, does anyone have idea from where this oil come from? It used to be from the loose o ring in the oil filter, but I dont know now. Any ideas?

Guys, I drop off the tranny pan. Here are the pictures. The oil housing o ring is dripping oil. We(service guy and me) think that this is oil from the engine and oil from the timing chain gasket that I replaced 3 days ago...back then 750Li was eating oil about half a liter on 2000km....


Or old oil from the timing chain gasket that was dripping, through the plastic engine cover and was going towards back of the car and glued to front of the tranny(u can see on one of the picture)

Most of the oil is on the plastic adapters and conectors...

What do you think? When u drive, oil from oil housing is getting on tranny...tranny is so DRY!!! NO LEAKING! Any ideas guys? Is it that transmission pump seal or crankshaft seal ?

I dont have idea? Is it serious? Is it possible that engine oil from oil filter housing cause this?
