Thanks for the reply wrxlaund. I just want this car to last without any major problems.. If the head gasket does go or is going, i would much rather sell it and buy a new suby without any headaches. Also how does the head gasket start leaking after the engine was rebuilt around 40k ago? The car is all stock... thats what i dont get.. I mean i know these engines have that problem, but 40k with no upgrades or modifications?
