Camshaft, Lifters and Push Rods: Service and Repair

Valvetrain

• Cylinder head bank 1 (right) is displayed in the following illustration.

• After installing the camshafts, the engine may not be started for approximately 30 minutes. The hydraulic adjusting elements must seat themselves (otherwise the valves will seat themselves on the pistons).

• After working on the valvetrain and lifters, carefully rotate the crankshaft by hand at least 2 full revolutions before starting to be sure that valves do not strike the pistons.

CAUTION!
When right camshaft timing chain cover is removed, the engine must not be turned over. Only when the chain tensioner for right camshaft timing chain and right timing chain cover are installed, the timing chain is secured against jumping off.
