  Note
t  Cylinder heads which have cracks between the valve seats or between valve seat inserts and the spark plug thread can be used further without reducing service life, provided the cracks do not exceed a maximum of 0.3 mm in width, or when no more than the first 4 turns of the spark plug threads are cracked.
t  After installing the camshaft wait for approx. 30 minutes before starting engine. The hydraulic elements should be allowed to sit in place (if not, the valves may press on the cylinder).
t  After working on the valve gear, turn the engine carefully at least 2 rotations to ensure that none of the valves make contact when the starter is operated.
t  Renew gaskets and seals.
