Also a head gasket leak will cause a lean condition and the engine will run wrong.
Well, in that case it's the exhaust then. Weird thing is, the gasket isn't blown out and there doesn't appear to be any of that junk on the front of the engine itself, or at least alot. I can't believe I've blown another gasket though. grrrr
