Removal
All engines
1. Disconnect the battery ground cable.
2. Remove the engine air cleaner (ACL) and the air cleaner outlet pipe.
3. Remove the engine cover.
4. NOTE: 4.6L engine shown; 5.4L engine similar.
Remove the crankcase ventilation tube from the valve cover.
Romeo engine (4.6L)
5. Disconnect the differential pressure feedback exhaust gas recirculation (EGR) sensor hoses from the EGR valve tube.
6. Remove the EGR valve tube.
^ Disconnect the upper and lower fittings.
^ Remove the tube.
Windsor engine (SAL)
7. Disconnect the differential pressure EGR feedback sensor hose from the EGR valve tube.
8. Remove the EGR valve tube.
^ Disconnect the upper and lower fittings.
^ Remove the tube.
All engines
9. Disconnect the LH fuel injector electrical connectors, ignition coil electrical connectors and the wire harness retainers.
10. Disconnect the camshaft position (CMP) sensor.
11. Disconnect the LH radio interference capacitor.
12. Position the engine control wiring harness off of the valve cover.
13. CAUTION: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces.
These tools cause scratches and gouges which make leak paths. Use a plastic scraping tool to remove all traces of old sealant.
NOTE: The intake manifold is removed for clarity.
NOTE: The bolts are part of the valve cover and should not be removed.
Remove the LH valve cover.
^ Fully loosen the bolts and remove the valve cover.
^ Clean the valve cover mating surface of the cylinder head with silicone gasket remover and metal surface prep. Follow the directions on the packaging.
^ Inspect the valve cover gasket. If the gasket is damaged, remove and discard the gasket. Clean the valve cover gasket groove with soap and water or a suitable solvent.
Installation
All engines
1. If a new gasket is being installed, apply instant adhesive completely around the gasket groove in the valve cover. Install the new valve cover gasket.
2. NOTE: If not secured within four 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.
Apply a bead of silicone gasket and sealant in two places where the engine front cover meets the cylinder head.
3. Position the valve cover and gasket on the cylinder head. Loosely install the bolts.
