Mark the position of the valve push tubes and injector push rods as they are removed. The push tubes and push rods must be installed in the same positions when the engine is assembled.

Loosen the rocker lever adjusting screws, and remove the valve push tubes and injector push rods.

Hold the push tubes and push rods while loosening the adjusting screws. Do not let them fall into the engine while rotating the accessory drive pulley.

NOTE: Some push tubes and rods are under compression because the valves are open. Rotate the crankshaft clockwise with the accessory drive pulley to relieve the spring tension.
