[Spits] fixing gearbox leaks

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.

My Spitfire's supposedly rebuilt gearbox drips oil onto the exhaust 
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.

Tanks,
