Valvetrain, servicing

Note:
^ 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.
