INSTALLATION
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.
NOTE: If the valve cover is not secured within four minutes, the sealant must be removed and the sealing area cleaned with Metal Surface Cleaner
F4AZ-19A536-RA or equivalent meeting Ford specification WSE-MSB392-A. Allow to dry until there is no sign of wetness, or four minutes,
whichever is longer. Failure to follow this procedure can cause future oil leakage.
1. Apply the silicone in two places where the engine front cover meets the cylinder head.
^
Use Silicone Gasket and Sealant F6AZ-19562-AA or equivalent meeting Ford specification WSE-M4G323-A6.
2. Position the valve cover on the cylinder head and loosely install the valve cover bolts.
