I would mount it dry, coated on each side with this PermatexSo I just removed the oil filter - can't be the issue. And also removed the oil filter plate. Found out that the mounting point, where the oilfilter plate is attached to the engine is not completely even - this might be what is causing a few drops to come out (see picture). This is what I'm trying to solve.
I've ordered complete new plate (13270-1170), O rings (670D1506 & 920551021), and the paper gasket (11060-1092). My question now is - how do I mount this paper gasket (11060-1092), put it on dry, and tighten it down? - or, soak it in oil before mounting it?, or use some kind of sealing stuff? (remember the engine plate is not completely even, I can feel the spot marked on the photo - a tiny bit uneven).
