Installation
1. NOTICE: 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 remove all traces of old sealant.
Clean the gasket mating surfaces.
-
Clean the valve cover mating surface of the cylinder head with silicone gasket remover and metal surface prep. Follow the directions on the
packaging.
-
Clean the valve cover gasket groove in the valve cover with soap and water or a suitable solvent.
2. Install a new gasket on the LH valve cover.
3. NOTE: If the valve cover is not secured within 4 minutes, the sealant must be removed and the sealing area cleaned with metal surface cleaner.
Failure to follow this procedure may cause future oil leakage.
Apply a bead of silicone gasket and sealant in 2 places where the engine front cover meets the cylinder head.
