  3. NOTE: Failure to use Motorcraft® High Performance Engine RTV Silicone may cause the engine oil to foam excessively and result in serious engine damage.
    NOTE: If the valve cover is not installed and the fasteners tightened within 4 minutes, the sealant must be removed and the sealing area cleaned. To clean the sealing area, use Motorcraft® Silicone Gasket Remover and Motorcraft® Metal Surface Prep. Failure to follow this procedure can cause future oil leakage.

    Apply an 8 mm (0.315 in) bead of Motorcraft® High Performance Engine RTV Silicone to the engine front cover-to-RH cylinder head joints.
