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 crankcase vent tube. For additional information, refer to the quick connect coupling in Section 310-00 .

2. NOTE: When removing the ignition coil-on-plugs, a slight twisting motion will break the seal and ease removal.

   Disconnect the 3 LH coil-on-plug electrical connectors and remove the 3 bolts and the 3 LH-coil-on-plugs.
   • Inspect the coil seals for rips, nicks or tears. Remove and discard any damaged coil seals.

3. Remove the oil level indicator.

4. Remove the 2 ground wire bolts from the engine front cover and the RH strut tower.

5. Remove the engine wiring harness from the LH valve cover.
   • Disconnect the 2 Variable Camshaft Timing (VCT) oil control solenoid electrical connectors.
   • Detach and disconnect the LH Heated Oxygen Sensor (HO2S) electrical connector.
   • Disconnect the 3 fuel injector electrical connectors.
   • Detach the 11 wiring harness retainers from the LH valve cover and stud bolts and position the harness aside.

6. 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 seal, carefully wiggle the valve cover until the bond breaks free or damage to the VCT seal and VCT oil control solenoid may occur.

   Loosen the 4 bolts and 7 stud bolts.
   • Remove the valve cover.
   • Discard the gasket.

7. Inspect the VCT solenoid seals. Remove any damaged seals.
   • Using the Differential Bearing Cone Installer and Handle, remove and discard the seal(s).

8. 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).

9. 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 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 solenoid seal(s).

3. 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.

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 seals in the valve cover are below the top of the VCT oil control solenoid electrical connector or the VCT seal may leak oil.

6. Install the engine wiring harness to the LH valve cover.
   • Position the wiring harness and attach the 11 wiring harness retainers to the LH valve cover and stud bolts.
   • Connect the 3 fuel injector electrical connectors.
   • Connect and attach the LH HO2S electrical connector.
   • Connect the 2 VCT oil control solenoid electrical connectors.

7. Position the ground wires to the engine front cover and the RH strut tower and install the 2 bolts.
   • Tighten to 10 Nm (89 lb-in).

8. Install the oil level indicator.

9. NOTE: Apply a small amount of dielectric grease to the inside of the ignition coil-on-plug boots before attaching to the spark plugs.

   Install the 3 LH -coil-on-plugs and the 3 bolts.
   • Tighten to 7 Nm (62 lb-in.
   • Connect the 3 coil-on-plug electrical connectors.

10. Install the crankcase vent tube. For additional information, refer to the quick connect coupling in Section 310-00 .
