Measuring Timing Chain Wear

WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: This procedure must be performed with the timing chain cover removed.
  1. Remove the timing chain cover (Refer to REMOVAL  ).
  2. To determine if the secondary timing chains are worn, rotate the engine clockwise until maximum tensioner piston extension is obtained. Measure the distance between the secondary timing chain tensioner housing and the step ledge on the piston. The measurement at point (A) must be less than 15mm (.5906 inches) (Fig 1 ).
