Inspect timing chain for stretching prior to removal.

Rotate engine while watching timing chain tensioner plunger. When the plunger reaches its maximum travel stop rotating engine.
Measure the distance from the tensioner body and the edge of the chain guide as shown in illustration.
If the distance is greater than 20.5 mm (0.81 in.) inspect guide shoes for excessive wear.
If guides are okay, replace timing chain.
