well, here's a timing belt that looks just dandy.

Yep, see it a lot. People don't think that the materials can age and degrade because they don't "look" old. Same situation with hoses and belts on most vehicles. Under hood temps have climbed a lot from the older vehicles. All the insulation and close packing give you little air movement and the heat just bakes everything.
