Noise coming from Engine Compartment After Header Install After the header install. I hear this weird knocking type noise from the engine compartment. It sounds external from the engine. I don't hear it @ idle or when I am cruising. Only when under a load. Its not detonation because EFI does not show any.
It kinda sounds like when you rattle a PCV valve. But it is in sync with the engine. It sounds like it is coming from the driver-side.
Any ideas? TIA.

Are your headesr hitting on anything or looks as if they are to close to hitting? If I remember right the Jet Hot's had an issue sometimes with hitting the k member? May be worth a check to get under the car and look.

But I will check it again. Since it wasn't there before the headers. I guess when I am under a slight load, the engine moves so the exhaust could rattle, then if I give it more gas. The exhaust could rest on the body and not rattle anymore. Hmm....
I don't think it is an exhaust leak, because if I give it more throttle. It goes away.
