Ensure that the camshaft sealing rings (1) are in place in the camshaft grooves. Camshaft sealing rings must be in place below the surface of the camshaft journal in order to avoid being pinched between the cylinder head and the camshaft caps.
Apply a liberal amount of lubricant to the camshaft journals and the right cylinder head camshaft carriers. Adhesives, Fluids, Lubricants, and Sealers
- Exhaust Camshaft (1) - Install
Position the camshaft lobes in a neutral position with the flats on the back of the camshafts up and parallel (1) with the right cylinder head camshaft cover rail.

- NOTE:
Ensure the proper camshaft position actuator is installed in the correct position. The dowel pin on the camshaft position actuator must be aligned with the slot in the camshaft nose for reassembly. Failure to install the proper camshaft position actuator can effect engine performance and set an engine code.
Install the camshaft position actuator (1) by inserting the actuator between the timing chain and front cover. While pushing the actuator into the tensioned side of the chain, tilt the actuator while engaging the chain, aligning the marks on the chain and place the actuator in the fully seated position.
- Carefully pry the camshaft forward and move the EN-49982 - 1 Retainers backward via the slot to reengage the position actuator to the camshaft. The dowel pin on the camshaft position actuator must be aligned with the slot in the camshaft nose for reassembly.
