The details are for 2008 and 2008 ford Taurus and Mercury Sable car models.


Valve Covers
REMOVAL & INSTALLATION
SEAL REPLACEMENT

Instructions are as follows :----


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).

  4. Disconnect the RH variable camshaft timing (VCT) solenoid electrical connector.
  5. Disconnect the 3 RH fuel injector electrical connectors.
  6. On early build engines, disconnect the heated PCV valve electrical connector.
  7. On all engines, detach all of the wiring harness retainers from the RH valve cover stud bolts.
  8. Remove the nut and the power steering pressure (PSP) tube bracket from the valve cover stud bolt.
    NOTE
    It is necessary to reposition the A/C tubes to remove the valve cover.
