ive noticed that at SOME times while i am driving or parked, that there is a tapping noise from possibly a loose bolt on the manifold.

only problem is that i cant seem to see which bolt is loose

help?

 

hows your heatshielding..

 

Sometimes you can feel the pulse of exhaust gas if you hold your hand close to the manifold bolts (one at a time), just don't touch anything, of course.
