Exhaust Manifold Clean and Inspect

1. Clean the manifolds in solvent.

CAUTION: WEAR SAFETY GLASSES IN ORDER TO AVOID EYE DAMAGE.

2. Dry the components with compressed air.
3. Inspect the exhaust manifolds for the following:
^ Damage to the gasket sealing surfaces.
^ Damage to the EGR pipe fitting (if applicable).
^ Damage to the take down studs.
^ Restrictions within the exhaust passages.
^ Broken or damaged heat shields (if applicable).





4. Measure the alignment or surface flatness of the exhaust manifold flanges using a straight edge and a feeler gauge.
If the surface flatness is not within specifications, the exhaust manifold is warped and must be replaced.
