Inspect Chain Tensioner Slipper and Damper

Chain tensioner slipper
Chain vibration damper
 
The areas where the slipper and damper are in contact with the timing chain become worn.
 
When this happens, the timing chain begins to vibrate, at which time the tensioner can no longer apply the proper tension to the timing chain, causing the timing chain to become loose and cause skipping, which could damage the valve mechanism.
