The most likely place is the front seal leaking down into the bell housing and running out the bottom and being blown onto the pipe. Of course, it might not be gear oil at all but the rear main seal of the engine leaking oil out into the bell housing where it is blown onto the pipe.

It's embarrasing, really. Visual inspection shows oil all over the outside, a classic case of external lubrication. I'm guessing that, appearances notwithstanding, it isn't really leaking through the metal casing nor even through most of the seams, but rather from just one or two key places, that the oil is being blown around to make it *look* like the casing is porous. And I'm thinking I need to pull it and re-seal it. So the question is, what would be the likely places? Front, rear, both, other seams? Don't know when I'm going to find the time to do this, but it needs to be done. Either that or build a shield.
