Well this escalated quickly.. op, do a compression test and a press test of the coolant system, were trying to save you money by not buying all those other parts to have the problem not go away. I agree with the head gasket as well, once its off put a straight edge across the head surface in all diff directions, if overheated these heads will warp and need to be decked true. If you still dont believe us then go head buy all those parts do as you must and come back and say same probs are happening, by then were done helping... its funny when someone asks advice 3+ ppl have a solution but its ignored and repeated over and over and over and over and over and over lol....
