Removal
NOTE:
Removal steps in this procedure may contain installation details.
NOTE:
Do not pull the engine appearance cover forward or
sideways to remove. Failure to press straight upward on the underside of
the cover at the attachment points may result in damage to the cover or
engine components...
Inspect the camshaft lobes for pitting or damage in the
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...
