Intake Manifold: Testing and Inspection

CLEANING

CAUTION: Remove all filings and foreign matter that may have entered the intake manifold as a result of service or possible damage to the engine may occur.

Remove all gasket material from the machined surfaces of the intake manifold. Clean the intake manifold in a suitable solvent and dry it with compressed air.

INSPECTION

CAUTION: Check the baffle plates on the underside of the lower intake manifold if so equipped. The baffles should be securely fastened or possible damage to the engine may occur.

Inspect the intake manifold for cracks, damaged gasket surfaces or other conditions that would make it unfit for further service. Replace all studs that are stripped or otherwise damaged. Clean the Exhaust Gas Recirculation (EGR) passages.
