I realized--after I replied--that I should have included that factor.

If you don't care if the car dies, there's no point in spending anything on
it outside of the bare minimum. My old '76 Dodge Coronet was in the "don't
care" category, so I'm quite familiar with that concept.

You mean me personally? I'm nuts, I know. But even nuts has its limits;
I'll eventually let the 'Teg go, one of these days.

Does Honda make any cars with non-interference engines?

why would you want one? they have lower power density.

besides, idiots get up here and bleat about "interference engines" here
all the time, apparently unable to grasp that fact that any 4-stroke
diesel is interference, but diesels are mysteriously missing from their
list of engines to complain about.

An automotive DNR?

Ford used to ... in the 1930's (and maybe later), their flat <L> head design

I don't know. Maybe the much older ones (~1980)...

I always understood that a Honda engine was interference as a matter of
course.

This turns out to be kind of a trivia question. The only non-
interference engine produced with Honda's name on it is the Honda
Passport with V6 (3.2L) engine, produced c. 1997-2002. But Honda
produced this car in a joint venture with Isuzu, which sold the same
vehicle under the name "Isuzu Rodeo."

Tegger reported around a 50% chance of bent valves when a Honda timing
belt breaks. I would say that is fair or that the chances of damage
are even a little less than 50%. The approximation comes from reading
many reports on Honda groups of valves not bending.

I suppose the pistons nudge the valves closed in many cases during the
remaining revolutions, sparing the valves damage. The valve pockets
(a.k.a. "valve reliefs") in the piston heads may help, too.

I've seen a lot of questions in various forums that could be answered
with a simple Google search. But I guess an answer with a person's
signature at the bottom of it means that it's better than Google! ;-)

Timing belts are one of the things I don't mess around with, even when
they cost upwards of $900 to replace, like on my Audi.

For me and many others on this forum that do our own maintenance, the
$100 bucks or so to replace the timing belt, tensioners and water pump
is cheap insurance. I have gatherering all these parts in
"anticipation" of the 7 year replacment interval. I'm actually more
worried about the water pump failing than the timing belt.

I wasn't complaining. I was just curious. BTW, what are Toyota engines?
