Stop by a repair shop and have them do a block test on the cooling system. They put some special blue chemical into their glass tester bottle, then they remove some coolant from the radiator, put the test bottle over the open radiator cap hole and run the engine for a few minutes, sucking in the air thats there. If the blue liquid turns yellow or green, you have a blown head gasket (very common on these motors), or a cracked head.
Me???first hand experience on mine!!! I also am an ASE Master technician.
