Lincoln MKX 2008-2009

WARNING

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.

1. Remove the crankcase vent tube.
2. Remove the LH ignition coils, as outlined in the Engine Electrical Section.
3. Remove the oil level indicator.
4. Disconnect the LH Variable Camshaft Timing (VCT) solenoid electrical connector.
5. Detach all of the wiring harness retainers from the valve cover and the stud bolts.

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.

1. Using the special tools, install new VCT solenoid and/or spark plug tube seals.
   
   WARNING

   Failure to use the correct RTV Silicone Sealant (TA-357) 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. Follow the directions on the packaging. Failure to follow this procedure can cause future oil leakage.
2. Apply a 0.31 inch (8mm) bead of RTV Silicone Sealant (TA-357, or equivalent) to the engine front cover-to-LH cylinder head joints.
