Condition
Some owners may comment on an apparent oil or coolant leak. Additionally, the comments may range from spots on the driveway to having to add fluids.
Cause
Intake manifold may be leaking allowing coolant, oil or both to leak from the engine.
Correction
Install a new design intake manifold gasket. The material used in the gasket has been changed in order to improve the sealing qualities of the gasket. When replacing the gasket, the intake manifold bolts must also be replaced and torqued to a revised specification. The new bolts will come with a pre-applied threadlocker on them.
Notice
An oil leak may result if the vertical bolts are not tightened before the diagonal bolts.
Diagonal bolts may require a crows foot to tighten.
Tighten
1. Tighten the vertical lower intake manifold bolts (1) to 7 N.m (62 lb in).
2. Tighten the diagonal lower intake manifold bolts (2) to 7 N.m (62 lb in).
3. Tighten the vertical lower intake manifold bolts (1) to 13 N.m (115 lb in).
4. Tighten the diagonal lower intake manifold bolts (2) to 25 N.m (18 lb ft).
