Intake Manifold

NOTE:

When the upper intake manifold (3) and lower intake manifold (1) are not aligned properly, cross threading of the upper intake manifold attaching bolts can occur. The graphic shows non-repairable damage to the lower intake manifold (1) due to cross threading of an upper intake manifold attaching bolt (2).

Check both the upper and lower intake manifolds for:

Damage and cracks.
Gasket surface damage or warping.
Check the fuel cross-over tube for damage or signs of abrasion, replace as necessary.

Check the lower intake manifold for:

Damaged fuel injector ports.

If either the upper or lower manifold exhibits any damaged or warped conditions, replace the manifold.
