Does the timing chain break ???? I would figure a chain would last
the life of the car, unlike belts.......

A timing CHAIN is made up of a few 100 metal links that rub and rotate against each other. They are designed to do this and oil is continuously applied. But over time they will wear gradually and play will develop. Modern (last 20 years) engines are designed to deal with a bit of this play but at some point they need to be replaced. If they break bad things can happen.

As to lasting the life of the car, when we drove cars 100K miles or less, well they usually did. (A 10 year old car with 100K miles in the 60s was usually a clunker worth little more than scrap.) I own cars with 210K, 135K, and 190K miles on them. "Life" has a new meaning than in days of old.

Unlike a belt, a chain very likely give you fair warning that it is
about to fail. Excessive noise and engine performance will appear. My
experience with chains is that a well lubricated chain will out last the
car. (Especially where roads are salted.) The people who generally have
problems didn't do proper oil changes. Yes the chains on S-series
engines do last more than 200k miles. Its been discussed here in the
past.
