Removal
1. Remove the Hydro-Boost brake booster.
2. Raise and support the vehicle.





3. Remove the screw and the dust shield.





4. Disengage the clutch release cable from the clutch release fork.
5. Lower the vehicle.





6. Remove the two screws and position the clutch release cable aside.





7. Remove the LH ignition coil cover bolts and the cover.





8. Disconnect the ignition coil electrical connectors.





9. Remove the ignition coils.





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





11. Disconnect the positive crankcase ventilation (PCV) valve from the LH valve cover and position aside.





12. Disconnect the wiring harness anchors and the engine coolant temperature (ECT) sensor.





13. Disconnect the electrical connectors from the fuel pulse damper, EGR vacuum regulator solenoid, supercharger bypass vacuum solenoid, and the differential pressure feedback EGR system.





14. Disconnect the vacuum hoses from the differential pressure feedback EGR system.





15. Disconnect the vacuum hoses from the supercharger bypass vacuum solenoid and the actuator.





16. Disconnect the vacuum hoses from the fuel pulse damper and the EGR vacuum regulator solenoid, and position the vacuum harness aside.





17. Position the accelerator and speed control cables aside.





18. Remove the vacuum accessory bracket mounting nut.





19. Remove the mounting bolts and the vacuum accessory bracket.





20. Disconnect the camshaft position (CMP) sensor electrical connector.





21. Remove the nut.





22. Remove the fasteners and position the power steering reservoir aside.





23. Remove the LH valve cover.





24. 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.

Clean and inspect the sealing surfaces and the valve cover gaskets. Install new gaskets, if necessary. Make sure the gaskets are correctly seated on the valve cover.

Installation





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

Apply a bead of silicone gasket and sealant to areas shown.





2. Install the LH valve cover and loosely install the bolts.





3. Tighten the LH valve cover bolts in the sequence shown.





4. Position the power steering reservoir back and install the fasteners.





5. Install the nut.





6. Connect the camshaft (CMP) sensor electrical connector.





7. Install the mounting bolts and the vacuum accessory bracket.





8. Install the vacuum accessory bracket mounting nut.





9. Position back the accelerator and speed control cable.





10. Connect the vacuum hoses to the fuel pulse damper and the EGR vacuum regulator solenoid, and position the vacuum harness back.





11. Connect the vacuum hoses to the supercharger bypass vacuum solenoid and the actuator.





12. Connect the vacuum hoses to the differential pressure feedback EGR system.





13. Connect the electrical connectors to the fuel pulse damper, EGR vacuum regulator solenoid, supercharger bypass vacuum solenoid, and the differential pressure feedback EGR system.





14. Connect the wiring harness anchors and the engine coolant temperature (ECT) sensor.





15. Connect the positive crankcase ventilation (PCV) valve.





16. Position the oil level indicator tube and install the bolt.





17. Install the LH ignition coils.





18. Connect the ignition coil electrical connectors.





19. Install the LH ignition coil cover and the bolts.





20. Install the clutch release cable and install the two screws.
21. Raise and support the vehicle.





22. Connect the clutch release cable to the clutch release fork.





23. Install the dust shield and the screw.
24. Lower the vehicle.
25. Install the Hydro-Boost brake booster.
