Cleaning

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

Inspection

 CAUTION: Remove all filings and foreign matter that may have entered the manifold as a result of service.

 CAUTION: Check the baffle plate(s) on the underside of the manifold if so equipped. The baffle(s) should be securely fastened.

Inspect the 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 EGR exhaust passages.
