Oil in the coolant

Patrick, the only other way coolant could mix with oil is if the turbo center housing water jacket cracked. Did you flush the cooling system good after you last rebuild? 
It's probably a bad HG/warped head. Was the head resurfaced and the block cleaned well before assembly? Might consider getting some ARP head studs so you don't have to buy new head bolts again.

OK guys, what ways, other than a bad head gasket, can oil get into the
coolant system? I have the UrS metal head gasket on the car (installed at
last timing belt job) which is fairly bullet proof from what I hear from the
UrS guys. But I've got oil floating in my coolant reservoir and am trying
think of all the other ways that oil can get into the system. Could a bad
seal/bearing in the turbo allow it's cooling water to get into the oil?
Thanks for any ideas of what else to consider before I pull the head.
