If you don't know the service history of the car, at 100K I'd be tempted to change it (and the associated guides) if you're intending on keeping it.
Not an insubstantial repair.
Whilst you'd normally hear a wearing chain, you'd only really know true wear when stripped down.
It mostly comes down to service history , if it's not been properly serviced on time (I'm talking oil changes predominantly) , you can't rely on anything.
