For 1990-2009 cars

Important: If camshaft replacement is required, the valve lifters must also be replaced.

1. Lubricate the camshaft journals and the bearings with clean engine oil.
2. Install 3 M8 - 1.25 x 100 mm (M8 - 1.25 x 4.0 in) bolts into the camshaft front bolt holes.

Notice: All camshaft journals are the same diameter, so care must be used in removing or installing the camshaft to avoid damage to the camshaft bearings.

3. Using the bolts as a handle, carefully install the camshaft into the engine block.
4. Remove the 3 bolts from the front of the camshaft.

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.

Important:

• | Install the retainer plate with the sealing gasket facing the engine block.

• | The gasket surface on the engine block should be clean and free of dirt or debris.

5. Install the camshaft retainer and the bolts.
6. Tighten the camshaft retainer bolts.

Tighten

• | Tighten the hex head bolts (3) to 25 N·m (18 lb ft).

• | Tighten the TORX® head bolts (4) to 15 N·m (11 lb ft).

7. Inspect the camshaft position (CMP) sensor O-ring seal. If the O-ring seal is not cut or damaged, it may be used again.
8. Lubricate the O-ring seal with clean engine oil.
9. Install the CMP sensor and bolt.
