Inspect Chain Tensioner

Plunger
Ratchet pawl
Stopper plate
Chain tensioner
 
If there is trouble with the chain tensioner, it will no longer be possible to apply tension to the timing chain, which will cause the timing chain to become loose and cause skipping, which could damage the valve mechanism.
 
1. When raising the ratchet pawl, check that the plunger can be moved by finger.
2. When moving the ratchet pawl back, check that the plunger locks.
 
HINT:
Make sure that the plunger moves smoothly without resistance.
Replace the tensioner if it malfunctions.
