11. Remove the RH valve cover.
z CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or
other abrasive means to clean the sealing surfaces. These tools cause scratches

traces of old sealant.
Remove and discard the gasket, clean and inspect the sealing surfaces.
12. Inspect the valve cover spark plug hole gaskets. Install new gaskets, if necessary. Make sure the gaskets are correctly seated on the valve cover.

the sealing area cleaned with metal surface cleaner. Allow to dry until there is no sign of
wetness, or four minutes, whichever is longer. Failure to follow this procedure can result in
future oil leakage.
Apply a bead of silicone gasket and sealant in two places where indicated. Klj . 3 ba
