Installation

1. 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 remove all traces of old sealant.

Clean and inspect the valve cover mating surface of the cylinder head with silicone gasket remover and metal surface prep and a plastic scraping tool. Follow the directions on the packaging.





2. 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.
3. If a new gasket is being installed, apply instant gel adhesive completely around the gasket groove in the valve cover.






4. NOTE: If the valve cover is 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. Failure to follow this procedure can cause future oil leakage.
