292 Exhaust manifold "flapper valve"?
Do y'alls' with 292's have this spring loaded "flapper valve" in your
exhaust manifold? I believe my engine is a '73, so it may not have been there on the original engine. Mine makes quite abit of noise, especially when the idle is under 1000 rpm. Anyone know what it does, or if I need it? The noise it makes makes it sound like something in the engine is wrong. |
