Installation
All engines
1. NOTE: Installation of new seals is only required if damaged seals were removed during disassembly of the engine.
NOTE: Spark plug tube seal installation shown, VCT seal installation similar.
Using the special tools, install new VCT solenoid and/or spark plug tube seals.
2. CAUTION: 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 silicone gasket remover and metal surface prep. Failure to follow this procedure can cause future oil leakage.
Apply an 8 mm (0.31 inch) bead of Motorcraft High Performance Engine RTV Silicone to the engine front cover-to-RH cylinder head joints.
3. Using a new gasket, install the RH valve cover, bolt and the 10 stud bolts.
