Manifold, Intake: Inspection
WARNING: This page is about a different variant/trim than selected.
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.
