[QUOTE="badcobra, post: 16813801, member: 20798"] In most cases on a mod motor, when a head gasket blows, it just pressurizes the coolant system and blows out the cap under boost. Does not get in the oil or blow out the tailpipe. Do a block test and test for c02 in the coolant expansion tank. You can also put a plastic bag around the expansion tank and use a carbon dioxide tester with the cap off. If the detector goes off, you have your answer. [/QUOTE]
