>Cars that still use timing belts

Seriously what the fuck? Why hasn't this shit gone the way of the dodo, how badly do you have to cheap out that you don't have chain for fucks sake.

Welcome to America.

Chains are heavy so they affect performance

This is a good read

mobiloil.com/en/article/car-maintenance/car-maintenance-archive/car-tuning-belt-drive-versus-timing-chain

I'm willing to bet it affects performance as much as 0.3%

Nothing wrong with a timing belt. They're a lot easier to change than a timing chain and they're out in the open where they can be inspected regularly. I've never looked at the timing chain on my 216k mile Toyota because it's a pita, but I probably should before I eat a chain tensioner or some shit.

The only thing you need to make sure is timing guides are good so it doesn't chew up the chain and that's like 150k miles when you should look. Timing chains are better in every single way.

truthfully, frankly, gear driven single cam pushrod engines are superior.

Disgusting

It's a good read, but doesn't account for any of the drawbacks of a belt like the wearing of plastic guides, belt stretch (which affects chains too but not as severely ir quickly I most cases), dry rot/cracking, etc. These problems are usually not seen with a chain driven cam or gear drive for that matter. That isn't to say that a chain is the holy grail, they can be noisier than a belt, are more prone to shear off cam gear teeth (on cheapo aftermarket gears), and can be harder to time correctly. I still prefer a chain for that little extra strength over the rubber/nylon belt.

probably a little more than that, but I doubt more than 1%. A timing belt will also be more precise, and responsive. I doubt you would feel either, but in a race might mean victory.

I agree completely, was just answering OP's question.

>tfw FA5 timing chain masterrace

Ugh I'mgonna have to change my timing belt in my dream cruiser soon. I don't know how to do it myself so there goes at least 600$.

I'm so glad Veeky Forums is such a car enthusiast board.

...

gear driven OHC masterrace

There is nothing wrong with belts

fuck off

hey dont knock the timing belt. it's a good design. forces people to do work on their engines every 100000km or so anyway.

also, diesels have a timing belt driven fuel pump that only lasts about 100 000km, the same age as the timing belt usually that needs maintenance. so from that perspective a chain is a waste.

it's going to be a bit more than that.
it's going to need an engine drop to get at that engine bay.

We use FAE forestry heads at work. They spin a half ton metal drum with hammers welded all over it at several thousand rpm and it's entire purpose is to fuck up trees quickly. The transmission from motor to drum is 5 serpentine belts next to each other, and they never break.

The point is just change the fuckers as routine maintenance like you would anything else, it's simpler than a chain system with it's need for more lubrication and more complicated guides.

chains are better though from the perspective of buying a new car. they'll last the life of the car. 400 000km+

>this delusional

lel

>gear driven dohc

Fuck ur shit

What engine is that to the right?

>what is noise, vibration, and harshness

easy to tighten up, easy to tell how when you have to replace it, easy to replace, cheap. god bless the timing belt (and pushrods).

A belt needs no lubrication, and instead of rubbing on guides it can be pressed in with a tensioner, which will keep the correct pressure on. Chain rubs on and wears the guides, while belts don't rub on things. Belts are quieter, chains generally last longer. Belts have less stretch than chains and stay more consistent through their life. On the other hand, if you don't change either when they should be changed, you can see chain progress as it stretches more and more, while the belt will stay the same until the teeth get ripped off.
From the user perspective, there isn't a hell of a lot of difference. Chains may be slightly noisier, but sound deadening and other tricks cut out the noise. Either way, the average person takes their car into the shop to have it done well past the time it should be done, regardless of which they have; assuming it hasn't snapped and the pistons and valves joined in holy matrimony.

i liek timing belts

Christ alive, what is that thing?

>Not using gears

pretty run of the mill Volvo redblock, this one is an LH 2.2 in an 86 245.

kinda dirty in there, huh

It is a stranger set-up than I have usually seen, I must say.

V-belts errywhere

>It is a stranger set-up than I have usually seen, I must say.

the fuck are you talking about? it is literally an identical setup to the fucking example picture on the wikipedia "timing belt" entry you fucking walnut.

errywhere

and they're not described in any service manual because they changed accessory layouts a couple times a year. lose any and finding the right size is just guessing

>valve driven engine
Fuck that

it's simple.

Belts for non-interference engines.
Chains for interference engines.

If you design an interference engine and put a belt on it, you should die.

a custom built gear driven cam nissan L28 stroked to 3.2. obscenely expensive compared to the engine its sat next to in that picture

Don't hate. The pt cruiser turbo is a sleeper.

We won't need to drop the engine. It can be done around that price range too.

>all those cogs

L series nissan

>If you design an interference engine and put a belt on it, you should die.
subaru engines do this... alot

Volvo master race here... Tool me 2 hrs to replace timing belt, water pump, and all tensioners and pulleys in between on my volvo 850. I only have to do this every 70,000 miles so it's not bad at all

chain non-interference here


where is your god

you do realize that non-interference engines are only feasible for forced induction? that's the difference. high compression ratio:interference.

huh, apparently is possible. I still hate your engine bay.

That is a Volvo engine? It looks exactly the same as old Audi and VW four and five cylinder engines like the NF or NG. Did they cooperate?

I came so fukkin HARD to this.

Hunng

>that angle

Muh dick

Can someone tell me what is in between the timing gears and what exactly it does

Locks them together so it doesn't lose time when you do a belt job, or so you can take the pulleys off without the cams spinning

Kinda what I figured, is there a specific name for one of these? I need one for taking apart my 5MGE

Wut. A race Hemi is a non-interference engine and had 12.5:1 In 1964. What's high comp to you friend?

are you me

>tfw I drive a 2.5 TDS Frontera
Feels good, mang. All gears. 20 years and nothing but oil changes.

Having done them before, its about the same as a Neon or doing a timing set on a Cavalier, Escort, Civic, etc. Usually we just pull the engine as its wayyyy easier in the long run to pull the engine and trans. On a Cruiser, id go ahead and replace the radiator while its taken apart as it will be going sooner rather than later if you are due for a timing belt.

mechanic here. You're retarded.
90% of all belt engines are interference.

Fun Fact: The GT86 is the only new Toyota that runs a timing belt. Because Subaru.

Good + Good = great. Enjoy your motor!

You're stupid.

Just because it's the way it's done doesn't mean that it's the correct way to do it, Cletus.
Also you're not a mechanic if you just fix your own shit in the yard next to your trailer.

You can just use vice grips, no reason to buy a special tool

>hurr non-interference engines are the best way of raising compression in order to facilitate higher combustion temps, more complete burning, more power and more efficiency.

Please, user. Just stop now before I fucking humiliate you.

I thought exactly the same. Looks very similar to my ABY.

I never said any of that.

I only said interference fit engines should have a chain instead of a belt.

Uhhh because the b6 audi s4 and rs4 scared them away.

This.

lol your cylinder head may be in my dining room

I've actually seen timing belt tensioners fail, these things are like those gas struts that lose strength over time. Never, ever get lazy and not replace these when changing the timing belt!

nobody said non-interference increases compression you mongoloid.

Sorry, try again. Motorcyclist here and we -know- belt drive is heavier for a given gear ratio than chain.
Regarding OP's question, it's simple. It's a difficult point of maintenance and adds planned obsolescence to a car. That way the manufacturer can either get a huge payday when it comes in for a belt change or get a huge payday when the owner buys a new car after they snap it.

Chains look pretty cool tho

Motorcycle=\= car
On snowmobiles, belt drives are usually lighter, and if day they're closer to the application inside a car engine.

> if day
I meant I'd say

lol

>Having valves at all

Why is there a ring clamp around the oil filter?

For easier removal maybe?

>buy a car with a 350 sbc

at least it was a good excuse to upgrade the exhaust

Problems from the last century?

what is this engine its fuckin adorable

>he says this while posting a picture of an engine that's been out of production for over a decade.

If the camshaft gear gets worn out, does that mean you have to replace the whole camshaft?

>using engines when you could use the force
fucking plebians

>easy to replace
Do you even know what a timing belt is?

>Worlds first flattering photo of a PT Cruiser

God awful. Even the engine bay cries of classless design philosophy.

Y so many chains

>thinks timing belts aren't easy to replace

honda D series here. it could not be easier

>you do realize that non-interference engines are only feasible for forced induction?

300+ hp N/A non-interference engines are literally everywhere.


>select all images with Pickup trucks

To stay on topic. What else besides water pump, tensioner and timing belt should be changed? Cam seals? Is that an important thing to check while in there?

If they are leaking change them, if not leave them be.

>What else besides water pump, tensioner and timing belt should be changed?
in a chrysler ... the brand.

>Just fuck my shit up!

senpai gears will never go wrong

literally will run like clockwork

>chains gliding across plastic on a $60k car

belts are cheaper to make, and easier to replace for your techs.
also they want it to break so they get money from the dealership.
