blowing air under exhaust manifold.

Turns out it was a head gasket. Surprisingly easy repair on the 4 cylinder 3.0

update on clacking noise
by: Terry

Actually more of a compressed air noise. I put my hand below the exhaust manifold and could feel hot air blowing out in sinc with the engine and hissing noise. I am hoping it's just the gasket. I ordered one on line and it should be here tomorrow. Anyone else have this problem?
