A cracked manifold can show up as an exhaust tick on a cold start, an exhaust smell or soot streaks at the ports. A worn or leaking gasket can make a similar tick, so these signs alone do not prove the manifold is the problem.

Fits

As a cast iron manifold for rectangular port heads, it also goes on the 1970-1974 Chevrolet Camaro. If your car is not named here, open the "Vehicles it fits" section and check your exact model and engine. This listing is one manifold, and each application takes one.
