11. CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to clean sealing surfaces.
NOTE: The intake manifold is removed for clarity.
Remove the LH valve cover.
^ Fully loosen the fasteners and remove the valve cover.
^ Clean the valve cover mating surface of the cylinder head with silicone gasket remover and metal surface prep. Follow the directions on the packaging.
^ Inspect the valve cover gasket. If the gasket is damaged, remove and discard the gasket. Clean the valve cover gasket groove with soap and water or a suitable solvent.
Installation
All engines
1. Apply instant gel adhesive completely around the gasket groove in the valve cover. Install the new valve cover gasket.
2. NOTE: If not secured within 4 minutes, the sealant must be removed and the sealing area cleaned with silicone gasket remover and metal surface prep. Follow the directions on the packaging. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.
Apply a bead of silicone gasket and sealant in 2 places where the engine front cover meets the cylinder head.
3. Position the valve cover and gasket on the cylinder head and loosely install the fasteners.
