2. On the side where you are disassembling, disconnect the spark plug wires from the spark plugs.
3. Mark the location of the studs with the wiring fastening brackets (see figure), pull the brackets off the studs.
4. Remove the oil filler cap and, on 3.0L models, disconnect the suction line.
5. Before removing the rear cover, remove the PCV valve (chapter 6), and on 3.8L models, set the air cleaner aside. On 3.0L models, remove the EGR tube from the exhaust manifold for better access. If you are removing the valve cover for any other service procedure, remove the upper intake manifold as instructed in chapter 4.
6. Unscrew the bolts connecting the valve cover.
7. Carefully remove the cover. If it is stuck, tap it with a soft-faced hammer to loosen it.
8. Remove any remaining gasket from the head and cap. Clean off any oil or dirt with a rag soaked in acetone or lacquer thinner.
9. Before screwing in the bolts, soak their threads with oil.
10. On 3.0L models, apply a bead ("cushion") of RTV sealant to the cylinder head adjacent to the intake manifold guides (in two places on the guide).
11. Place the new gasket and install the cover.
Note: On 1991 and later 3.0L engines, the old gasket can be reused if it is in good condition.
12. Tighten the bolts to the specified torque value, working around the cover in several stages.
13. Install the parts removed earlier for ease of work. Add coolant if you drained it.
