c'mon buddy - it was a joke!

The flat six 3.0s (like my wife's OBW) have a chain.

I once had a '51 Chevy that stripped a timing gear!

Its also quieter and allows for lightweight components

So if you're going to make statements like that, back it up.

How many engines out there are fitted with timing belts, how many with
chains, how many with gears ?

Why is Subaru better/worse than any others?

A more intriguing question is "why are so many engines interference
designs where a belt failure is catastrophic?"

I believe the answer on that has to do with efficiency of the cylinder
design, et al, but it's never been explained to me in sufficient
detail for me to fully get on board with that.

I thought it was because they are quieter, but wish they were NI.

 I read that the SOHC will have less damage if a belt breaks.
Something about the DOHC free wheeling and bending all the valves.

AS - 03 Jan 2008 06:19 GMT
I am with jim on this one, I think belts are a big business and a lousy
alternative, the owner ends up putting out the money the manufacturer
saved, but:

Chains:  Normally last the life of the engine, are noisy, sprockets and
idlers are lubricated by the engine, you hardly ever hear of
catastrophic chain failure.

Belts:  Quieter, low cost, idlers have bearings which will require
replacing at least every other belt change, belts are guaranteed to
fail, and sometimes even ahead of time, (think Audi)

Gears:  Expensive, wont allow for flexible engine designs.

Hurray for rotary engines with no valves.

For the same reason that Honda and Toyota still do - cost, quietness
compared to a chain, lightness, etc.

By the way some of you argue seemingly in favor of timing belts, I guess
you like to shell out money and spend time replacing timing belts.  I do
not.

Then you can shell it out up front for the more expensive engine because of
heavier components and the chain; nothing is free.

bigjimpack@gmail.com - 05 Jan 2008 13:44 GMT
How would a chain make it more expensive?  The Suzuki SX4 states
timing chain on the sticker and a loaded AWD version is <$19k.   A car
at that price point isnt likely to use anything more expensive than it
needs to be.  How much heavier? Eight ounces?  Whoaaaaaaa!  Belts are
nothing but a scam to create more maintenance costs for consumers.  I
see no benefits and those who do are usually mechanics who love
getting $500 to swap a $40 belt.

The chain is only one of the heavier components.  More metal in the
components makes them more expensive.  Add up all the markups and the
addition of the parts and you'll end up paying the same with no additional
benefit.  Nothing is free; nothing.  You pay for it one way or the other.
One is visible, the other is not.  Your choice.

I always thought it was precision.

Look at printer and copier mechanisms, precision industrial robots,
etc...

They use toothed belts in place of chains.

Chains are sloppy.

It could very well be.  I'm sure you're right.  However, my point is that it
isn't just a big maintenance rip-off; there is a trade-off somewhere and you
will pay for that trade-off one way or another.

I don't.  There is no reason except to rip off consumers to use

rip off? $300 is is tiny % of costs associated with hitting  100K miles

    $600 - oil changes
    $1000 - tires

EVERY car needs the oil, gas, tires etc.  There is NO need to add an
extra $500 for a timing belt change which will end up being more for
those who change it 2x or more or those fools who buy vehicles that
need a belt change at 60k.

Then you should probably buy a low-performance, cheap car with a timing
chain.  That way you can use regular gas, cheap parts, etc.  Its all false
economy.  But there is no conspiracy here.  They have advantages building
cars in one way or another, and those advantages are either reduced cost,
better performance or whatever else.  There are trade-offs and you get what
you pay for; no more, no less.

Well, let's see here; The timing chain equipped H6 3.0 Soob engines (to
my knowledge)all recommend premium fuel. The 4 cyl Soob engines ALL have
timing belts.

So....I guess you have no reason to post to this group anymore.

Your point is?  I wouldnt bother with a 6 cyl subaru in a wagon or
sedan as the performance increase isnt noticable and the fuel economy
suffers.  I wouldnt use premium no matter what it says as it is a
waste of money and will cause no damage despite what those brainwashed
think.  I do not plan on buying another subaru until they fire the
current deigners and engineers and make the outback what it used to
be.  The new subes from WRX on down are just plain ugly.  New outback
has poor ergonomics and has lost the raised roof and big foglights.
The GT lost the hood scoop and the tribeca- dont even get me started
on that one.   I will keep my 04 for a couple more years as the wife
is up for a new car next.

I test drove a 2008 4 cylinder Outback before purchasing a 2003 6
cylinder Outback last summer.  I noticed the performance increase of
the 6 cylinder enough to decide that I really wanted a 6 cylinder
Outback.  But I am annoyed that Subaru no longer will sell a 6
cylinder Outback without all the expensive options that I am not
interested in.  But I like the 6 cylinder enough that I plan to
purchase a 2 or 3 year old one next time.

I guess I have been "brainwashed"  ;)  -- I use premium in my 2003 6
cylinder Outback and my 1993 BMW 525i.  The 1989 Volvo 240 wagon gets
mid-grade.

While I like (Jeep) Wranglers, to say they are quality shoots a hole in your
own theory about saving money.
Jeeps 4.0 have been known to crack exhause manifolds, so much that out local
junk yard sells aftermarket replacements.
Jeeps love to leak; Seen countless rear axle seals, some with 30k-60k miles,
lots of leaks around the transfer case and transmission.

And the premium gas is not a scam. We have had a few 6 cylinders running
like crap due to lower octain gas. I believe the 6 cylinders rule is premium
suggested, if performance problems is noted, then go to a higher octain.

That's why the Jeep is a big IF.  Chrysler quality is always a

Toyota was smart theyd have revived the FJ cruiser as a direct

And I bet that extended warranty costs more than a pair of $500 timing
belts.  And based on owner reports rolled up in Consumer Reports every
year, if reduced mtc costs are your interest, neither of those
manufacturers are exactly known for reliability.

If you want a chain and an engine that doesnt' seem to have major mtc
problems, the Subaru H-6 seems like one of the less trouble prone
you'll find, based on what I've read here for 6 years.

I've not heard anything bad about the 6 cylinder Subaru engine - in fact
everything I've read is very positive about it.

Unfortunately, you have to go to an Outback to get that engine. No offence
to those who like the Outback! :) I've never found the Outback very
appealing - I have no off-road pretensions, and the styling always seemed a
bit garish to me with the add-ons... To my mind it would be nice to see a
regular legacy wagon with 6 cylinder...

Cheers!

Warranty covers anything From AC to trans.  So spending $1k is worth
it.  Paying for "maintenace" in a ripoff.  I don't give much
credibility to consumer reports after they bashed the Trooper.   Right
before that they had the trooper as reliable as the landcruiser- The
Standard for off road vehicles.   I wont buy an outback until they
make it look good again

And because the performance would be down as well as the mileage, you
probably spent more on regular gas than you would have on premium, and you
ran the risk of damaging the engine.

Like I said; nothing is free.  You will pay for it all one way or another.

One of my cars requires 93 minimum.  It runs like crap on anything less; no
guts and absolutely abysmal gas mileage.  The other requires 91 and 89 can
be used in a pinch.  It runs OK on 89 but gas mileage sucks.  So I have done
the math on that one.  It costs about 10% more to use a lower grade of fuel.
On the car that requires 93, I wouldn't even attempt it.  It runs very
poorly on 91 on a hot day.

That's why the Jeep is a big IF.  Chrysler quality is always a

correction: Subaru requires t/b change @ 104K miles.

anyways, if you do not like, do not buy it. I do not see your problem.
there are plenty of other cars to chose from.

My mtc book said 100k but then from several sources i was told they
changed their mind about that and were recommending 60k.

the 2.2 engine used in the 95 called for 60K intervals, those used the

I agree too.
In my opinion, a timing chain cover leaks more often and costs a lot more to
repair. Some belts are a PITA and others are easy. I've seen timing chain
tensioners in Nissans fail, and with a chain the manufactures always seem to
have interference heads, so as well as the head damage, you have metal and
plastic in the oil. The engineers do many things we wonder about, but
designing an engine around "getting more maintenance" doesn't seem to be one
of them.
When I chose my wife's car, belt or not was not even a choice.
I wanted a 4 cyl over a 6. Repairs are cheaper when you can get your hand
into the engine.
It was going to be a camery and the 2.2 was a great engine. Non
interference, easy belt to change, but the Toyotas have changed to the 2,4
with a chain. Also is the new VVIT, where the timing gear on a cam can vary
for emissions/performance. No EGR system, and those can be a PITA. But some
other cars have had some issues with cam timing, so give up the reliable
belt to a unproven chain. I had to rely on the Toyota name, and it's been a
good car. Wouldn't care if it had a belt.
We could take this same argument and look at belt/chain/shaft drive on
motorcycles. Lots of trade off for each one

Anyway, my 2 cents,

I was curious to reasons why engeneers wouls use one over the other and
found this.
From
http://www.valvoline.com/carcare/articleviewer.asp?pg=pht20020901bd&cccid=4&scccid=5

There are many more advantages to a belt-drive system than ease of use. A
belt drive can increase power over a timing chain through less frictional
loss, more precise timing, smoother valvetrain motion and eliminating
windage caused by the timing chain and gears running in oil. A belt drive
also isolates the crankshaft's torsional vibrations from the camshaft better
than a chain (and certainly better than gear drives, which can amplify crank
harmonics). Think of it as a second harmonic damper for the rotating
assembly. And with all that engine builders are doing to stabilize
cylinder-to-cylinder camshaft timing, such as larger-diameter cams, doesn't
it make sense to do what you can to precisely phase the camshaft to the
crankshaft?

Hi BigJim, All!

>Why does Subaru still use a timing belt.  Eventhe newcheapo suzuki sx4
>has a chain

A belt probably gives a more consistent valve timing over the life of
the belt, and doesn't require an oil bath. Useable at higher RPMs too.

Perhaps a better question would be:

"Why do manufacturers insist on putting interference engines into
consumer vehicles?"

A broken  timing belt or chain is merely an inconvenience in an NI
motor, but is often a disaster of the highest degree (read "new
motor") on an interference engine.

And I fully understand that an interference type head/piston
arrangement means higher flow, more power, possibly even slightly
better efficiency, but it _also_ means that you'd better watch that
timing belt, buddy! Or else!

Just as an aside, last summer I acquired for cheap a '99 Forester with
under 100K that had what sounded like a bad rod bearing in it's 2.5L
SOHC motor. Turned out to be a failed idler bearing. (Bonus!)

When I performed the 105K service on my wife's '02 Forry (also with
the SOHC motor) a couple months ago, the belt looked OK, but several
idlers were going, particularly the same cogged idler that had failed
on mine.

What this means is that simply replacing the belt does not guarantee
that you're good to go for another 100K; you absolutely _must_ check
all of the idlers that the belt rides on (including the waterpump),
and replace any that aren't perfect. Or, do as I do, and simply
replace everything while it's apart. $igh.

And just one final note; I have heard it said that the EJ22 (as found
on early Legacys/Imprezas) is an NI engine. Don't count on it; I've
seen at least two with bent valves resulting from timing belt failures
. . .

I don't like interference engines, and wonder who they can't cut
reliefs for the valves in the piston tops. I have heard of ones that
had Tripple chains.

I had wondered why I have seen timing belts sold with the idlers. I
should have realized they can go bad, but never owned a car with a
belt. I had a friend who was upset because a mechanic told him his VW
needed a new motor, since the motor had a knock. When the friend told
me his Oil Light was on, and he had been driving it for THREE Mos like
that. I Had to check it out. The knock was coming from the front of
the motor, near the TB cover, and didn't sound like a valve, rod, or
anything I had heard before. I pulled the cover and the idler was
moving with metal shavings on a flange. I told him That was his
knock.

Figured the oil light sending unit was bad or something. Told him to
pick up the parts and I would fix it. Changed the idler and sending
unit, and the oil light was still on. Took it out and poked in the
hole, and the oil light went off, so sludge was blocking it. My friend
was pissed that the mechanic was going to charge him 1600$ for a new
motor.  Having a knock and no oil pressure did sound bad, but Not
being able to drive it for very far.

The Subaru H-6 3.0 liter uses a timing chain.

And if you want to see a mess, take one of those apart.

Oh, come on, two long-a.s chains with tensioners under a cover with
about 300 little bolts, what's not to like?
With the water-pump chain driven, I think.

Chains are far better.  Even with all the parts the failure rate is so
low as to be negligible.  Chains usually last the life of the engine
or at least several 100k.  I drove a 73 Mercury Montego with 351W and
never noticed chain noise.  On a Subaru 4 cyl who would notice that
either?   Belts are an easy way to make an extra $500-1000 on the
price of a vehicle.

Forgot to mention the $$ the manuf. gets selling tensioners, idlers,
covers (rusted screws dislodge nut inserts from cover) and of course the
labor $$ the dealers get.

The group that loves timing belts the most is mechanics.

You probably couldn't hear it over the pushrods.  <G>

What rpm range did the 351W do most of it's operation at?

I've never had a chain fail, but I've had them get worn sloppy, as
well as had a tensioner fail.  The broken tensioner let the chain slip
all kinds of teeth.

I had a '74 Ford pickup with a 302W that had so much timing chain
stretch at 20K miles that it was slapping the cover. It sounded like a
rod knock it was so bad.

And if they used chains with the heavier parts, extra lubrication and cost
of the chain, the car would probably cost an extra... $500-$1000.   Nothing
is free.

Because Sunaru depends on 40% of it's income
from planned obsolence and degradation of internal
engine parts and 300% markups from the dealer
to bring the money in. I bought my first
Subaru in 2002. I was the WORST mistake I ever
made! Their dealer service sucks a.s and you're SOL
with them as far as warranty service is concerned
unless you like to do battle with corporate morons.
As far as I am concerned they should ship half the
Subaru cars in the USA to Iraq for AlQuaada to
use as car/suicide bomber platforms. That's all they
are good for. My next car will be a Honda like I had before
I went and bought a Subie-piece-of-shi+.
