The oil mist coaleses and pools in the gap between the IAD and the air 
runners. Then the pool can wick out to the ends of the sleeve; no cracks in 
the sleeve are necessary. It doesn't take much, other than time, for this to 
happen. And this will happen while the car is parked, so it has plenty of time.

Okay, then it's just from overfilling or from oil mist from the breather.

I can't remember if you mentioned that the left side of your AT was wetter 
than the right. If so, you probably need  a new O-ring for the governor cover. 
I have them, or you may still be able to buy them from the VW dealer.
