Exhaust Manifolds

Cleaning

Clean exhaust manifold (9430) mating surfaces.

Inspection

Inspect exhaust manifold(s) for cracks, damaged gasket surfaces, or other wear or damage that would make them unfit for further service. Inspect cylinder head joining flanges of exhaust manifold(s) for evidence or warpage with a straightedge. Minor warpage can be corrected by surface grinding. If warpage is extreme, replace exhaust manifold. Refer to Specifications at the end of this section.
