Stop guessing at it and diagnose it! Go to an auto parts store that loans tools and do a compression test. If you have the extra cash and an air compressor, get a leakdown tester. Somewhere between $50-$100 should get you one that will be good enough. The compression test will tell you if you need to worry about the head gasket, and the leakdown will will let you know what has failed, if anything. If you need help with doing either test, just let us know.
