Huh? Exactly how do belts provide "much better timing precision" than
chains?

We've all heard the squeal of a radiator or power steering belt slipping
if the tension isn't correct, but never a timing belt. The timing belts
I'm familiar with are toothed to prevent slippage, much like a chain
turning a sprocket. Here's an example of a timing chain and sprocket
complete with chain tensioner from a 1988 Porsche Carrera:

And you know this how?

 

Any links to support this claim?

 

:-(

 

Wrong! The subject of the sentence is "neither", which is singular.
Without the qualification ("of these two statements") it would read
"neither is wrong" (not "neither are wrong").

I cannot recall seeing someone asserting so much in Usenet yet providing
so little supporting links, etc. Clearly a legend in your own mind.

I hate to tell everybody this, but GM owns Ditech, the huge loan firm. Part

because they don't stretch!!!

that tensioner's on the slack side of the chain!!! it doesn't prevent
stretch!!! and the degree of stretch is substantial - as you can see in
that pic.

 

how do you /not/ know this??? examine the facts!

 

indeed, but the tensioner on the "tight" side of the chain is subject to
a lot more wear, /and/ adjusting it to keep the timing correct is a
highly non-trivial [and expensive] task. that's why most manufacturers
just have a tensioner on the "slack" side and to heck with the timing.

ok, there are three things: mileage, time, quality. a belt can break
because of age, not just mileage. and quality is the largest
determinant of all. crap belts don't last. oh, and one last thing -
don't forget that a lot depends on the wrench jockey that last changed
it. too tight will kill a belt in short order and it's /not/ the fault
of the belt.

no, whiners and the ignorant hate them. two facts: chains stretch,
belts don't.

and like i said earlier - there's plenty of reason to use chain from the
bean-counter perspective - lower overall product life being the best
one. bmw invest heavily in lower overall product life - "sealed for
life" transmissions anyone?

so far we have one alleged to be that. some are spectacularly easy - a
15-20 minute job. don't they count?

that's a belt quality issue. manufacturers like honda and subaru have
extended their belt change interval to 105k. it's on google.

judge for yourself dave - if people don't even know about this stuff,
and that's been proven many times in this thread alone, let alone on the
workshop floor, how are they going to diagnose properly?

rubbish. the run on ohc, by definition, is many times longer than block
mounted.

dude, you don't know what you're talking about. see above.

 

by definition, as the chain stretches, the timing drifts. think about it.

 

"running with the old chain" doesn't mean the thing's not stretched to
25 degrees out and making the car run like a pig. chains stretch. when
that happens, the timing drifts. that's bad. belts never stretch.
sure, there are low quality belts, but use one that is good quality.
there are a finite number of belt patterns, and a large number of
manufacturers. find a good one, even if oem is poor.

ok, let me re-state for the pedants:

"neither of these two statements are wrong".

happy now?

no dude,

1. they're into life limitation. metal fatigue. if you want a more
visible example, check out their "sealed for life" transmissions.

2. bmw "recycle". look it up. no other manufacturer does that because
it costs money and the used metal recovery business is already highly
efficient. bmw do it to remove used parts from the market, and thus,
they sell more cars.
