active area. Minor pitting is acceptable outside the active area. The
active area includes the opening ramp and closing ramp. The opening ramp
is the point where the lifter just begins to lift until the point it
reaches the nose of the lobe. The closing ramp is the point from the
nose back down to the lash point. The base circle of the camshaft is not
the active area.
