For 1990-2009 cars

Important: Use a new cylinder head cover gasket and new seal washers whenever the cylinder head cover replacement procedure is performed.

Ensure that the new gasket and the new seal washers are correctly positioned during the cylinder head cover installation.
1. Install the new cylinder head cover gasket to the cylinder head cover.
2. Install the new seal washers to the cylinder head cover.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Install the cylinder head cover to the cylinder head. Secure the cover using nine bolts (1,2,3).

Tighten
Tighten the cylinder head cover bolts to 10 N·m (7 lb ft).
