Yeah, it's looking like there is an exhaust leak, but now the valve train sewing machine sound is constant. Got my appointment for Monday at Donway Ford, so hopefully this gets taken care of along with my messed up Pony projectors.
Good that you are taking it in. As for an exhaust leak. You have to remember that there are exhaust valves popping open and snapping shut constantly in the cylinder head/ combustion chamber area causing metal to metal contact so if indeed you have an exhaust leak, especially at the head ( manifold gasket) you will definately be hearing valve train noise from the valve action.
Anyways, lets hope for the best and not speculate too much till they look it over.
