11. Attach the transmission fluid level indicator tube and the bracket to the rocker arm cover.
12. After ensuring all rocker arm cover reinforcement washers are installed in their original position,
tighten the rocker arm cover screws to the proper specification.
13. Install the spark plug wires.
14. Install the PCV valve and hose.
15. Install the engine oil fill cap.

3.0L Engine
The valve covers installed on the 3.0L engine incorporate integral (built in) gaskets which should last
the life of the vehicle. Replacement gaskets are available if required.
1. Disconnect the negative battery cable. Disconnect the ignition wires from the spark plugs, but leave
them attached to their wire looms.
2. Remove the ignition wire separators from the rocker arm cover attaching bolt studs with the wires
attached, then lay the wires out of the way.
3. If the left hand cover is being removed, remove the throttle body assembly, the PCV valve and fuel
injector harness stand−offs. If the right hand cover is being removed, remove the engine harness
connectors, fuel injector harness stand−offs and air cleaner closure hose from the oil fill adapter.
4. Using caution, slide a sharp thin blade knife between the cylinder head gasket surface and the valve
cover gasket at the four RTV junctions. CUT ONLY THE RTV SEALER AND AVOID CUTTING
THE INTEGRAL GASKET.
5. Remove the integral gasket from the valve cover gasket channel. Note bolt/stud fasteners locations
before removing gasket for correct installation. Clean gasket channel and remove any traces of RTV
sealant.
To install:
1. Align fastener holes, lay new gasket onto channel and install by hand. Install gasket to each fastener,
seat fastener against cover and at the same time roll gasket around fastener collar. If installed
correctly all fasteners will be secured by gasket and not fall out.
2. Install valve cover to the engine, lightly oil all bolts and stud threads. Apply a bead of RTV sealant at
the cylinder head to intake manifold rail step (two places per rail).
3. Place the valve cover on the cylinder head and install attaching bolts and studs. Tighten the attaching
bolts to specifications.
