So I could still have a cracked head, even though there isn't pressure in the cooling system when cold? That sucks. But it does have 260k miles on the original head. What really makes me mad is the previous owner had $12k in reciepts from the guy he bought it from, but his wife threw them all out, so I have no idea what all was done to the car. I am pretty sure that when I flushed the system out, that I would have gotten any oil that could have been in the system out, but who knows. Maybe I should do another flush? I did add Water Wetter to the coolant, is it possible that it could do something to cause the oil? I know one thing I am going to check tomorrow morning is if there are any bubbles in the expansion tank at startup. If there is then I guess I can assume the head has to come off
