11. Remove the 4 bolts and the TB and spacer assembly.
- Discard the gasket.

12. Disconnect the 4 LH fuel injector electrical connectors.

13. Disconnect the fuel supply tube. For additional information, refer to Fuel System - General Information Service and Repair.

14. Remove the nut and the LH radio interference capacitor.

15. Disconnect the Camshaft Position (CMP) sensor electrical connector.

16. Detach the 3 wiring harness retainers from the LH valve cover studs.

17. Remove the bolt and position the oil level indicator tube aside.

18. Remove the 8 bolts, 2 stud bolts and LH valve cover.
- Remove and discard the gaskets.

- NOTICE: 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.

Clean the mating surfaces with silicone gasket remover and metal surface prep. Follow the directions on the packaging.

- Inspect the mating surfaces.

Installation

1. Install new gaskets. Make sure the gaskets are correctly seated on the valve cover.





2. NOTE: If the valve cover is not secured within 4 minutes, the sealant must be removed and the sealing area cleaned with metal surface prep. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer. Failure to follow this procedure can result in future oil leakage.

Apply a bead of silicone gasket and sealant in 2 places where the engine front cover meets the cylinder head.
