look for soot around where the manifold and the cylinder head meet......
even start it up and give it a good blip on the throttle and look for
a puff of black smoke and soot........


this is a simple test......(and cheaper to repair than a turbo......)




Agree with what you say. Mine was caused through a stud breakingthere by causing the gasket stuff up. Ended up having to having to get the manifold faced as well.
