Valve Cover

Removal & Installation

Right Valve Cover

To Remove:

1. Disconnect the negative battery cable.
2. Disconnect engine control sensor wiring from the ignition coil and disconnect the spark plug wires from the right-hand spark plugs.
3. Disconnect the engine control sensor wiring from the intake air temperature (IAT) sensor and the mass air flow (MAF) sensor.
4. Disconnect the vacuum line.
5. Remove the ignition coil bracket.
6. Disconnect the crankcase ventilation tube.

   NOTE: Slide a flat knife between the valve cover gasket and cylinder head to loosen the silicone gasket and sealant from the cylinder head. This will keep the valve cover gasket from stretching.

7. Remove the bolts, valve cover, and if necessary, the gasket.

To Install:
