Installation





1 Note: If 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-M513392-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.

Apply a bead of silicone in two places where the engine front cover meets the cylinder head.
- Use Silicone Gasket and Sealant F7AZ-19554-EA or equivalent meeting Ford specification WSE-M4G323-A4.





2. Position the (A) valve cover and the valve cover gasket on the (B) cylinder head, and loosely install the bolts.
