Tools Required

J 36660-A Torque Angle Meter

1. Remove the left rocker arm cover. Refer to Valve Rocker Arm Cover Replacement .
2. Remove the right rocker arm cover. Refer to Valve Rocker Arm Cover Replacement .



3. Remove the rocker arm pedestal and retaining bolts.

Important: Place the assemblies on a clean surface. Store the component in order so they can be reassembled in the same location and with the same mating surfaces as when removed.

4. Remove the pedestal and rocker arm assembly.
5. In order to complete installation, observe the following assembly tips:

•	Clean the rocker arms and pedestal bolts in a suitable solution and inspect for wear.

•	Clean the rocker arm pedestal bolts of all thread adhesive.

•	Apply thread lock compound or equivalent to the bolt threads before assembly.

1. Install the pedestal and rocker arm assembly.

Notice: This bolt is designed to permanently stretch when tightened, and therefore MUST be replaced anytime it is removed. The correct part number fastener must be used to replace this type of fastener. Do not use a bolt that is stronger in this application. If the correct bolt is not used, the parts will not be tightened correctly. The system or the components may be damaged.

2. Install the rocker arm pedestal retaining bolts.

Tighten
Tighten the bolts to 15 N·m (11 lb ft). Use the J 36660-A in order to rotate the bolts an additional 90 degrees.

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 right side rocker arm cover. Refer to Valve Rocker Arm Cover Replacement .
4. Install the left side rocker arm cover. Refer to Valve Rocker Arm Cover Replacement .

Tighten
Tighten the bolts to 10 N·m (89 lb in).

5. Inspect for proper completion of the repairs.
6. Listen for valve train noise.
