Important: The pushrods have a different degree of hardness at each end. The end with a paint stripe identifies the upper end of the pushrod. If the paint stripe is not visible, mark the pushrods on the upper end as they are removed.

1. Use the following steps in order to position the engine so that no valves are close to a piston crown:

1.1.	Rotate the engine until the mark on the crankshaft balancer is at 2 o'clock.

1.2.	Rotate the crankshaft counterclockwise 88 mm (3 ½ in).

1.3.	Align the mark on the crankshaft balancer with the first lower water pump bolt (about 12:30).

2. Disconnect the battery negative cables from the batteries. Refer to Battery Cable Replacement in Engine Electrical.
3. Remove the air cleaner assembly with the mounting brackets from the engine block. Refer to Air Cleaner Assembly Replacement in Engine Controls-6.5L-L65.
4. Remove the left or right front wheel housing panel. Refer to Wheelhouse Panel Replacement in Body Front End.
5. Remove the valve rocker arm cover from the cylinder head. Refer to Valve Rocker Arm Cover Replacement .

Notice: Store and mark all valve train components in an exact order so they may be reassembled in the same position from which they were removed.

6. Remove the valve rocker shafts retaining bolt from the cylinder head.



7. Remove the valve rocker arm shaft assembly from the cylinder head.



8. Remove the pushrods from the engine block.



9. Use the following steps in order to remove the rocker arms, if necessary:

9.1.	Insert a screwdriver into the valve rocker arm shaft bore.

9.2.	Break off the end of the nylon valve rocker arm retainers.

9.3.	Remove the valve rocker arm retainers with a pair of pliers.




10. Slide the valve rocker arms from the shaft.
11. Inspect for obstructions in the pushrod oil passages. Verify that the pushrod oil passages are clean.

Important: One type of valve rocker arm is used for the intake and the exhaust valves.

1. Install the pushrods in the valve lifters.

Notice: All valve train components must be reassembled in the exact order and position from which they were removed.

2. Install the valve rocker arms to the valve rocker arm shaft.
3. Use the following steps in order to install the valve rocker arm retainers:

3.1.	Center the valve rocker arms on the corresponding holes in the valve rocker arm shaft.

3.2.	Use a drift of at least 13 mm (½ in) diameter.

3.3.	Install the new retainers.




4. Install the valve rocker arm shaft assembly.
5. Ensure that the ball ends of the pushrods seat in the valve rocker arms.




Notice: Improper installation of the valve rocker arm shaft bolt may cause valve rocker arm shaft breakage and /or piston to valve contact.

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.

6. Install the bolts for the valve rocker arm shaft assembly.

Tighten
Tighten the bolts alternately to 55 N·m (40 lb ft).

7. Rotate the engine by hand. Make sure that the valve train moves freely.
8. Install the valve rocker arm cover to the cylinder head. Refer to Valve Rocker Arm Cover Replacement .
9. Install the left or the right front wheel housing panel. Refer to Wheelhouse Panel Replacement in Body Front End.
10. Install the air cleaner assembly with the mounting brackets on the engine block. Refer to Air Cleaner Assembly Replacement in Engine Controls-6.5L-L65.
11. Connect the battery negative cables to the batteries. Refer to Battery Cable Replacement in Engine Electrical.
