Cover(S), Cylinder Head: Removal: Right
The magnetic timing wheels (1) must not come in contact with magnets (pickup tools, trays, etc.) or any other strong magnetic field. This will destroy the timing wheels ability to correctly relay camshaft position to the camshaft position sensor.
- Disconnect and isolate the negative battery cable.
- Remove the air inlet hose and upper intake manifold (2). Refer to MANIFOLD, INTAKE, REMOVAL .
- Cover the open intake ports (1) to prevent debris from entering the engine.
- Disengage the starter harness to main harness retainer (3).
- Disengage two starter wire harness retainers from the right cylinder head cover (1).
- Remove the variable valve timing solenoids. Refer to SOLENOID, VARIABLE VALVE TIMING, REMOVAL
.
- Disengage four main wire harness retainers (1) from the right cylinder head cover.
- Disengage the main wire harness retainer (2) from the right cylinder head cover mounting stud.NOTE:
If removing both RH and LH Camshaft Position (CMP) sensors, mark the sensors so they can be installed in their original locations.
- Remove the CMP sensor. Refer to SENSOR, CAMSHAFT POSITION, REMOVAL
.
- Disengage three injection/ignition harness retainers (1) from the right cylinder head cover.
- Remove the ignition coils. Refer to COIL, IGNITION, REMOVAL .
- Remove the Positive Crankcase Ventilation (PCV) valve. Refer to VALVE, POSITIVE CRANKCASE VENTILATION (PCV), REMOVAL
.
- Loosen the nine cylinder head cover mounting bolts (1) and three studbolts (2) and remove the cylinder head cover.NOTE:
The LH cylinder head cover is shown, the RH cylinder head cover is similar.
- Remove and discard the cylinder head cover gasket (1).
- Remove and discard the spark plug tube seals (2).NOTE:
The LH cylinder head cover T-joints are shown, the RH cylinder head cover T-joints are similar.
CAUTION:Do not use oil based liquids, wire brushes, abrasive wheels or metal scrapers to clean the engine gasket surfaces. Use only isopropyl (rubbing) alcohol, along with plastic or wooden scrapers. Improper gasket surface preparation may result in engine fluid leakage.
- Remove all residual sealant (1) from the cylinder head, timing chain cover and cylinder head cover mating surfaces. Refer to ENGINE GASKET SURFACE PREPARATION .
