Yep, sounds like a head gasket leaking. If it pressurizes the tank almost immediately after start-up, that is your problem. The early Duramax's have had problems with head gaskets from what I have read. Also, have you done an oil analysis to see if you have coolant in the oil or are you just looking at the oil?
