The flat six 3.0s (like my wife's OBW) have a chain.
I once had a '51 Chevy that stripped a timing gear!

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 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.

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.

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.

Look at printer and copier mechanisms, precision industrial robots, etc...
They use toothed belts in place of chains.
Chains are sloppy.

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.

bigjimpack@gmail.com - 06 Jan 2008 15:50 GMT 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.

bigjimpack@gmail.com - 06 Jan 2008 17:29 GMT That's why the Jeep is a big IF. Chrysler quality is always a crapshoot. That's what extended warranties are for though. If Toyota was smart theyd have revived the FJ cruiser as a direct wrangler competitor instead of an ugly impractical waste of money. Toyota name, four doors, removable top and theyd sell like hotcakes. I had personal experience with a turbo passat 01.5 same as audi. "Required" premium never got it. Many many problems but none related to fuel. LAsted 140k+ then was on its way out for tranny and other issues. They new Jeep uses a 3.8l which is reputed to be pretty good.

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.

Fred Boer - 06 Jan 2008 18:56 GMT 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...

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.

However, my point is that >>it [quoted text clipped - 3 lines] > > I agree. 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,

StephenW - 06 Jan 2008 07:22 GMT 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?
S - 03 Jan 2008 19:24 GMT 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 . . .

houndman@phonom.net - 03 Jan 2008 20:26 GMT > Hi BigJim, All! > [quoted text clipped - 45 lines] > University of Colorado > (719) 262-3101 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.

bigjimpack@gmail.com - 04 Jan 2008 20:32 GMT 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.

The group that loves timing belts the most is mechanics.

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.

It sounded like a rod knock it was so bad.
JD - 05 Jan 2008 13:38 GMT 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.
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.

Eventhe newcheapo suzuki sx4 > has a chain 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+.
