REMOVAL

Remove Positive Crankcase Ventilation (PVC) valve hose.

Remove cam cover fasteners.
Remove the cam cover assembly.
INSTALLATION

NOTE: Inspect the cam cover isolations for cracks. Replace the isolators if deterioration exist. Gaskets over one year old may take a set and should be replaced. Gaskets under one year old do not need replacement. A small drop of RTV must be installed at the two T-joints whenever the cam cover is installed.

Install new cam cover gaskets, if removed.
Install the cam cover assembly.
Install the PVC valve hose.
