For more information about camshaft bearing replacement, refer to Camshaft Bearing Removal .Installation Procedure
- Install the valve lifters into the lifter bores.
- Install the anti-rotation brackets on the valve lifters.
- Install the screws that retain the anti-rotation brackets.
- Install the cylinder head.
Notice: If the valve lifters and anti-rotation brackets are not installed properly, the valve lifters, the anti-rotation brackets, and the engine could be damaged.
Important: When installing new valve lifters, coat the lifters with an approved engine oil supplement.
| • | Align the flat sides (top) of the lifters with the flat sides of the anti-rotation brackets. |
| • | When properly aligned, the flat side of each lifter is aligned parallel to the anti-rotation bracket. |
| • | The roller at the bottom of each lifter is aligned parallel to the camshaft lobe. |
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.
Tighten
Tighten the anti-rotation bracket screws to 11 N·m (97 lb in).
