Need Help w/Oil Leak

[Sketchy1985E30]

I have a weird oil leak that I can't track down. The drip is coming from the transfer case right where the flywheel access is. I have checked the usual leaking points and I do not see it leaking. It seems to be coming off the back of the engine and leaking into transfer case. Another weird thing that I noticed is that the engine idle speed decreases when I remove the dipstick. Is it possible that the oil pressure sensor is broken? It is not leaking there though. Please help...I am losing about a quart every day.

I would think that could be a main seal.

I have a 1985 E30 (325e)...just figured you'd figure it out from my screen name.
