Paul, The timing chain and gears are new as well as the timing chain
tensioner. I tried turning the rotor anti-clockwise. There is a small
degree of slop before the spring pressure is felt and when the rotor is
released it does not return completely to the clockwise stop. The rotor
will move a few degrees counter-clockwise before the spring pressure is
felt. There is no sideways movement. Does that sound correct or is there
too much play in the rotation?
