Chains can be engineered to last a long time, but very few in passenger cars
are. The last car I had that used a chain needed the chain (actually,
chains) replaced at 90K miles and the car wasn't worth the labor at that
point. Step one was to remove the engine from the car because there wasn't
room to remove the cover in the car.

Before there were belts the stories of jumped and broken chains were as
common as the belt stories today.
