Inspection Procedure
WARNING: This page is about a different variant/trim than selected.
- Inspect the manifold for the following conditions:
- Loose threaded inserts (1)
- Damaged MAP sensor bore (2)
- Damaged fuel injector bore (3)
- Damaged gasket or sealing surfaces (4)
- Damaged or broken vacuum fittings (5)
- Debris or restrictions within the passages of the manifold
- Inspect the composite intake manifold assembly for cracks or other damage.
- Inspect the intake manifold cylinder head deck for warpage.
- Locate a straight edge across the intake manifold cylinder head deck surface.
Position the straight edge across a minimum of two runner port openings.
- Insert a feeler gauge between the intake manifold and the straight edge.
An intake manifold with warpage in excess of 3 mm (0.118 in) over a 200 mm (7.87 in) area is warped and should be replaced.
- Locate a straight edge across the intake manifold cylinder head deck surface.
