Camshaft Position Actuator Oil Control Valve Replacement - Bank 1 (Right Side) Intake

Camshaft Position Actuator Oil Control Valve Replacement - Bank 1 (Right Side) Intake

Special Tools
* J 39946 Crankshaft Socket
* EN 46327 Timing Chain Retention Tool
* EN 46328 Camshaft Holding Tool

Removal Procedure




1. Remove the right actuator housing. DO NOT remove the camshaft position (CMP) actuator solenoids from the housing. Refer to Camshaft Position Actuator Housing Replacement - Right Side (Camshaft Position Actuator Housing Replacement - Right Side).
2. Remove the crankshaft balancer. Refer to Crankshaft Balancer Replacement (Service and Repair).

Note: The secondary timing chain has black links that are used for alignment when the primary and secondary timing gear and chain assemblies are being installed together. IT IS NOT NECESSARY for the black chain links to be aligned with the camshaft actuator timing marks when the secondary chain and gear components are being serviced separately.

3. Using the J 39946 , rotate the crankshaft until both Bank 1 (right) camshaft position (CMP) actuator timing marks perpendicular (90 degrees) to the cylinder head deck surface and near the top of their rotation.




Warning: Refer to Camshaft Holding Tool Warning (Camshaft Holding Tool Warning).

4. Install the EN 46328 (2).




5. Install the EN 46327 (1, 2, 3, 4) using the procedure below:




6. Use a paint stick to create a mark on the timing chain link (1) adjacent to each camshaft position actuator timing mark (2, 3).




7. Use an open end wrench on the hex cast into the right intake camshaft to prevent the camshaft from rotating when loosening the camshaft oil control valve.
8. Loosen and remove the right intake oil control valve.

Installation of the J 46327 Timing Chain Retention Tool - Right Bank




1. Rotate the wing nut (3) of the EN 46327 to the top of its travel.




2. Position the bottom retention tool on the cylinder head with the V-notch of the block (1) adjacent to the right exhaust camshaft actuator timing sprocket and chain as shown.




3. Insert the hook end (1) into a secondary timing chain link as shown.




4. Rotate the wing nut until it contacts the retention tool block (1). DO NOT tighten the wing nut at this time.




5. Rotate the wing nut (3) of the EN 46327 to the top of its travel.




6. Position the top retention tool on the cylinder head with the V-notch of the block (1) adjacent to the right intake camshaft actuator timing sprocket and chain as shown.




7. Insert the hook end (2) into a secondary timing chain link as shown.




8. Rotate the wing nut until it contacts the retention tool block (1). DO NOT tighten the wing nut at this time.




9. Tighten the EN 46327 wing nut against the retention tool block (1).




10. Tighten the EN 46327 wing nut to provide slack in the secondary timing chain between the two camshaft actuators (1, 4) as shown.

Installation Procedure





Caution: Refer to Fastener Caution (Fastener Caution).

1. Install the oil control valve through the opening in the right intake camshaft position actuator and thread it into the right intake camshaft.




2. Ensure both camshaft actuator timing marks (2, 4) are aligned with the paint marks (1, 3) on the secondary timing chain previously created.




3. Use an open end wrench on the hex cast into the right intake camshaft to prevent the camshaft from rotating when tightening the camshaft oil control valve to 120 Nm (89 lb ft).




4. Remove the EN 46327 (1, 2, 3, 4).




5. Remove the EN 46328 (2).
6. Install the crankshaft balancer. Refer to Crankshaft Balancer Replacement (Service and Repair).




7. Install the right camshaft actuator housing. Refer to Camshaft Position Actuator Housing Replacement - Right Side (Camshaft Position Actuator Housing Replacement - Right Side).
