1. Using the VCT Spark Plug Tube Seal Installer and Handle, install new VCT solenoid and/or spark plug tube seals. 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 in illustration, VCT solenoid seal installation similar.
2. 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. 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 silicone gasket remover and metal surface prep. Failure to follow this procedure can cause future oil leakage. Late build vehicles
3. Using a new gasket, install the LH valve cover and tighten the 9 stud bolts. Tighten in the sequence shown in illustration below to 10 Nm (89 lb-in). Early build vehicles
4. Using a new gasket, install the LH valve cover and 11 stud bolts. Tighten in the sequence shown in illustration below to 10 Nm (89 lb-in). All vehicles
5. Connect the 3 LH fuel injector electrical connectors.
6. Attach all of the wiring harness retainers to the valve cover and the stud bolts.
7. Install the wiring harness retaining bracket and the 2 nuts. Tighten to 4 Nm (35 lb-in).
8. Connect the 2 engine control wiring harness electrical connectors.
9. Attach the 2 wiring harness retainers.
10. Connect the LH VCT solenoid electrical connector.
11. Install the oil level indicator.
12. Install the LH ignition coils. For additional information, refer to «ENGINE IGNITION - 3.5L»(ref-355995) .
13. Install the ACL outlet pipe. For additional information, refer to «REMOVAL AND INSTALLATION»(ref-355993-S28735189342010013000000) .

Note. 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.

Note. 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.
