Wait about 30 minutes after installing the camshafts before starting
the engine. Hydraulic valve compensation elements have to settle
(otherwise valves will strike pistons). 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.
