One sepentine belt and tensioner -$150

Obviously you do your own repairs. Good for you but if you don't have
your own shop and a decent set of tools, the economics change
drastically.

Back when I used to have one of those ****ing engines that would
self-destruct when the timing belt broke, the cost to replace the belt
(parts and labor) was very near $900...and I could never find a
competent shop to do it cheaper. And the damn belts
had to be changed every 60,000 miles.

Are you saying snapped timing belts is no longer a problem? I thought
most modern engines hated a snapped belt (they're called "interference
engines").


My engine doesn't have a belt.



More and more are going to chains again, and non-interference
engines are also becoming more common.

Chains don't last forever either - I used to change quite a few
timing chains on inline 6 and V8 engines - and LONG before 100,000
miles. Quite a few before 60,000


Nothing lasts forever but the operant words are 'used to'. I used to
change a lot of things on engines forty years ago.
