Well I have never had problems (except lift pumps) with my truck and the coolant level is always between full and empty. I finally added a comp to my truck which is causing my ETH to run at 50 PSI boost on stock head gasket and I noticed coming back from Kansas City that my overflow bottle is completely full and blowing coolant all over the engine compartment, what a mess. I check the oil and is about two quarts low too, but does not look like there is any antifreeze in it. How can you tell if oil is in the antifreeze? It looks clean, but I not sure since I do not know what oil looks like when mixing with antifreeze I does appear to look. I was going to get a sample of the oil done since it is time to change the oil anyway to see if there is any coolant. I do not see any leaks around the head except for a very slight bit, just damp around the front of the block. Engine temps are normal too if that makes any difference. So my question is could this be just a bad radiator cap or is the head gasket blown or other? Right now I am kid of getting a sick feeling that my head gasket is blown internally, but since I do not know much I thought I would get your guys opinion. Thanks,
Doug
