I guess there's quite a bit of variability encountered in t-belt
condition-- even for comparable age (and/or use). This might be due,
in part, to the wide geographical variations in ozone level.
I suspect that mileage correlates less-well with belt-breakage than
does the belt age (unless the failure is induced by another failed
component--like the distributor gear). Bernie, you seems to be
saying that it _will_ be OK to replace the plastic distributor gear
_before_ it breaks? You're not saying this to just make us feel
good, are you? To avoid a violation of principle, I guess we could
merely remove the cam cover and inspect that gear every few years to
make sure to replace only if it's about to disintegrate. :-)
Speaking of "other" components that can induce t-belt failure, I
stumbled upon a potential "belt buster" --one I caused by the simple
act of trying to check the t-belt condition. A "self-inflicted"
wound, so to speak. A day or two before attempting to remove the
"allen" nuts that retain the plastic (t-belt) cover, I applied
penetrating oil to the heavily corroded hex sockets. However, as I
easily loosened the top nut with my Allen wrench, I was unaware that
the nut actually remained frozen and that its threaded stud was
unscrewing from the engine. Before I knew it, I had unthinkingly
pulled out the entire thing (nut with attached stud). There was a
simultaneous, metallic "clink" sound. Whoa, what's happened!!?
Duh... I then realized that inadvertant removal of the stud had
allowed a large steel bushing--a "spacer"--to come free and fall
into the interior of "t-belt territory". I could direct my
flex-light** into the lower regions and saw that the steel spacer had
become lodged between the T-belt teeth and the water pump gear teeth.
If this situation had been unnoticed, I don't know if it would have
caused a sudden catastrophy--or merely a disconcerting rattle. I was
barely able to retrieve the spacer with my "flexible claw" tool. In
any case I then decided to replace the belt.
Hey, I've saved my 11 yr-old belt, and I'll make it available as a
replacement to anyone who decides his 15+ yr-old old belt might be
"about to break". Waste not, want not. ;-)
[**Flex Light--my advice is to get one if you don't already have
it!!!!. Costs a mere 15 bucks at Sears (slightly more at Pep Boys)
and gives you much more precise, useful illumination in hard-to-reach
areas than you _ever_ thought possible. This thing makes a flashlight
seem like a using a butcher knife when a scalpel is really needed.]
