Removal & Installation

Left Side

Specific to:

Ford Taurus 2008-2009

Mercury Sable 2008-2009

1. Remove the LH ignition coils.
2. Remove the oil level indicator.
3. Disconnect the LH variable camshaft timing (VCT) solenoid electrical connector.
4. Detach and disconnect the 2 engine control wiring harness electrical connectors.
5. Detach all of the wiring harness retainers from the LH valve cover stud bolts.
6. Disconnect the 3 LH fuel injector electrical connectors.
7. Loosen the 11 stud bolts and remove the LH valve cover. Discard the gasket.
8. Inspect the VCT solenoid seals and the spark plug tube seals. Replace as necessary. Refer to SEALS.
9. Clean the valve cover, cylinder head and engine front cover sealing surfaces with metal surface cleaner.

To install:

NOTE

Installation of new seals is only required if damaged seals were removed during disassembly of the engine. Refer to SEALS.

NOTE

Failure to use the correct 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.

1. 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.
2. Using a new gasket, install the LH valve cover and 11 stud bolts. Tighten in the sequence shown to 89 inch lbs. (10 Nm).
