I have a persistent and very small oil leak/drip. It all started sometime back when I had a noise in the left side (alternator) cover. I pulled the cover off and replaced the gasket and then the leak started. Because there is so much stuff attached to the side cover, running around the side cover, and just the shape of the side cover itself, it is extrememly difficult to see exactly where the oil is coming from. I have since pulled the cover off again and really cleaned the gasket surfaces and replaced the gasket again. I thought I had replaced the shift lever gasket as well, but now it might be coming from there. Since it is a hassle to get the cover off, I want to get some opinions before I take it back apart. Is there any real pressure inside that cover? Could something like the oil pressure sensor be leaking and allowing the case to pressurize and push oil out? I know the cover could be warped and I can test that, but it is unlikely. I want to order all the possible gaskets before I take the cover off, but things like the oil pressure sensor are fairly expensive.
