Camshaft, Lifters and Push Rods: Service and Repair
Valvetrain
• Cylinder head and guide frame may only be replaced together.
• After installing the camshafts, the engine may not be started for approx. 30 minutes. The hydraulic equalization elements must seat themselves (otherwise the valves will crash into 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.
• Always replace gaskets and seals.
