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

Mitsubishi 2600 4 cyls (used by Chrysler for years) had 0ver 6 feet
of chain in them and they were notorious for dropping the chain that
drove the balance shafts and the oil pump - letting the engine
continue to run with no oil pressure and self destruct.

Anything that can break an engine (including overheating which none seem to have protection for) should cut the fuel immediately with a sensor. Basic obvious design. How stupid are people who design cars?



I see, so we should have a sensor that will detect a broken timing chain
and stop the engine, which is running at 3000 RPMs, in time so that the
piston won't hit a valve. You should work on that.

We do have sensors and warning lights and messages for many of the
serious, common things, eg over temp, low oil pressure, low oil level.
They work for me. But then you're the guy who says you never change
the oil, only add oil when it's half empty, etc. Serious people who
contemplate such things also weigh the issue of disabling a car because
it's gone over temperature, versus letting you continue to drive it,
at your own risk, if you happen to be in a tunnel, fleeing a fire,
or driving through a high crime area. Already, many of the incidents
of these sensors giving warnings are false alarms, due to the sensor
being faulty. How many more would you like to add? Sounds to me
like another one of your solutions in search of a real problem.
