Removal
NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, may cause engine failure.
NOTICE: Early build engines have 11 fastener valve covers, late built engines have 9 fastener valve covers. Do not attempt to install bolts in the 2 empty late build valve cover holes or damage to the valve cover will occur.

Installation
All vehicles
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 solenoid seal installation similar.
Using the VCT Spark Plug Tube Seal Installer and Handle, install new VCT solenoid and/or spark plug tube seals.
2. NOTICE: 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 in) bead of Motorcraft High Performance Engine RTV Silicone to the engine front cover-to-LH cylinder head joints.
