I initially thought I had a head gasket leak but after getting the car up on jacks and checking to see if my oil/coolant had mixed I had confirmed it wasn't a gasket leak. So the oil is leaking out near the headers (not really sure what they're called in a turbo application) and I have no clue what it is. Maybe cam seals?
 
Cam seals leak into the timing belt area. Not sure on the 2Gs but 1gs can develop a leak around the center exhaust manifold bolt. I would "guess" valve cover gasket as most likely.
 
The 1G center exhaust mani bolt goes into a water passage on the head. Have mine apart and in front of me right now so you would see coolant from that if it was leaking. I would guess valve cover too.

Fixed, like SrKegler said. And it's something found on all 4G63 DSM heads.
