Valve Cover - LH

















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, can cause engine failure.

NOTE: Installation of new spark plug seals or Variable Camshaft Timing (VCT) seals is only required if seals are damaged.

1. Remove the engine appearance cover. For additional information, refer to Engine Appearance Cover- Exploded View [1][2]Access Cover, Engine.

2. Remove the crankcase vent tube.





3. Remove the LH ignition coils.

4. Remove the oil level indicator.

5. Disconnect the wiring harness connector.
- Detach the wiring harness connector pin-type retainer from the LH valve cover.






6. Detach the 2 wiring harness retainers from the LH valve cover stud bolts and position the harness aside.





7. Disconnect the 2 Variable Camshaft Timing (VCT) oil control solenoid electrical connectors.
- Detach the wiring harness pin-type retainer.






8. Detach the 2 wiring harness pin-type retainers.





9. Disconnect the LH Heated Oxygen Sensor (HO2S) electrical connector.
- Detach the wiring harness connector pin-type retainer from the LH valve cover.






10. Disconnect the 3 fuel injector electrical connectors.
- Detach the 2 wiring harness retainers from the LH valve cover stud bolts.






11. NOTE: Coolant hose removed from graphic for clarity.
Detach the 2 wiring harness retainers and position the harness aside.






12. NOTICE: While removing the valve cover do not apply excessive force to the Variable Camshaft Timing (VCT) oil control solenoid or damage may occur.

NOTICE: If the Variable Camshaft Timing (VCT) oil control solenoid sticks to the VCT (Variable Camshaft Timing) seal, carefully wiggle the valve cover until the bond breaks free or damage to the VCT (Variable Camshaft Timing) seal and VCT (Variable Camshaft Timing) oil control solenoid may occur.

Loosen the 4 bolts and 7 stud bolts.
- Remove the valve cover.

- Discard the gasket.


13. Inspect the VCT (Variable Camshaft Timing) solenoid seals. Remove any damaged seals.
- Using the Differential Bearing Cone Installer and Handle, remove and discard the seal(s).






14. Inspect the spark plug tube seals. Remove any damaged seals.
- Using the Spark Plug Tube Seal Remover and Handle, remove and discard the seal(s).






15. Clean the valve cover, cylinder head and engine front cover sealing surfaces with metal surface prep.

Installation

1. NOTE: Installation of new seals is only required if damaged seals were removed.
Using the VCT (Variable Camshaft Timing) Spark Plug Tube Seal Installer and Handle, install new spark plug tube seals.






2. NOTE: Installation of new seals is only required if damaged seals were removed.
Using the Differential Bearing Cone Installer and Handle, install new VCT (Variable Camshaft Timing) solenoid seal(s).






3. NOTICE: Failure to use Motorcraft(R) 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(R) High Performance Engine RTV Silicone to the engine front cover-to-LH cylinder head joints.






4. Using a new gasket, install the LH valve cover and tighten the 4 bolts and 7 stud bolts.
- Tighten in the sequence shown to 10 Nm (89 lb-in).






5. Make sure the VCT (Variable Camshaft Timing) seals in the valve cover are below the top of the VCT (Variable Camshaft Timing) oil control solenoid electrical connector or the VCT (Variable Camshaft Timing) seal may leak oil.





6. NOTE: Coolant hose removed from graphic for clarity.
Attach the 2 wiring harness retainers.






7. Connect the 3 fuel injector electrical connectors.
- Attach the 2 wiring harness retainers to the LH valve cover stud bolts.






8. Connect the LH Heated Oxygen Sensor (HO2S) electrical connector.
- Attach the wiring harness connector pin-type retainer to the LH valve cover.






9. Attach the 2 wiring harness pin-type retainers.





10. Connect the 2 Variable Camshaft Timing (VCT) oil control solenoid electrical connectors.
- Attach the wiring harness pin-type retainer.






11. Attach the 2 wiring harness retainers to the LH valve cover stud bolts.





12. Connect the wiring harness connector.
- Attach the wiring harness connector pin-type retainer to the LH valve cover.






13. Install the oil level indicator.

14. Install the LH ignition coils.

15. Install the crankcase vent tube.





16. Install the engine appearance cover. For additional information, refer to Engine Appearance Cover- Exploded View [1][2]Access Cover, Engine.
