Removal
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 mating surfaces with silicone gasket remover and metal surface prep. Follow the directions on the packaging.Installation

NOTE: If the valve cover is not secured within 4 minutes, the sealant must be removed and the sealing area cleaned with metal surface prep. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer. Failure to follow this procedure can result in future oil leakage.
Apply a bead of Motorcraft® High Performance Engine RTV Silicone in 2 places where the engine front cover meets the cylinder head.
