10. 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 the valve cover mating surface of the cylinder head with silicone gasket remover and metal surface prep. Follow the directions on the

Installation
1. 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. 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.
