Timing Chain Guide: Testing and Inspection






Inspect The Chain Guide For Wear:
The surface between the outer grooves of the chain guide should not indicate any contact marks. If this surface does show signs of wear, the guides will also have to be replaced (see Figure 3-B). In that instance, the repair will have to be carried out in the usual way (i.e. engine out of car).
