Cleaning
Remove all gasket material from the machined surfaces of the upper and lower intake manifolds. Clean the manifolds in a suitable solvent and dry it with compressed air.
Inspection
NOTE: Remove all filings and foreign matter that may have entered the manifold as a result of service.
Inspect the manifold for cracks, damaged gasket surfaces, or other problems that would make it unfit for further service. Replace all studs that are stripped or otherwise damaged. Clean the EGR exhaust passages.
Check the baffle plate(s) on the underside of the manifold if so equipped. The baffle(s) should be securely fastened.
