Inspect the valve cover for damage. Install a new valve cover if necessary.
Installation
CAUTION: Do not use abrasive grinding discs to remove gasket material; only use manual scrapers. Do not scratch or gouge aluminum sealing surfaces or oil leaks may occur.
Clean and inspect the sealing surfaces of the valve cover and the cylinder head. Both surfaces must be clean and flat.
NOTE: The valve cover gasket and the valve cover must be installed and the bolts tightened to specification within four minutes of sealant application.
Apply a 3 mm (0.1 inch) bead of silicone sealant in two places where the front camshaft bearing cap meets the cylinder head.
