Lots of great TB info here, but one question not quickly answered: how critical is on-time replacement?
Situation: last full TB/WP was at 90K (dealership, OEM parts). Now at 140k, 15 years after the last service. So, at about half the miles but twice the age. The truck has seen very light duty over this time.
What’s the collective experience here about pushing the clock? I’ve seen timing belts in this same scenario come out of the engine looking brand new. Anything about the 100 that consumes them? Is it possible to check the condition?
And, what consequence if it fails? Are the V8s interference engines?
