Installation
All vehicles
1. NOTE: If not secured within four minutes, the sealant must be removed and the sealing area cleaned with metal surface cleaner. 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 gasket and sealant in two places where the engine front cover meets the cylinder head.
2. Position the valve cover and the valve cover gasket on the cylinder head, and loosely install the bolts.
