I've driven plenty of cars with timing belts. Even when it breaks it's ordinarily not too big a deal, not much worse than running out of gas. In other words, you stop and you aren't going again until it's replaced.

Whole different story with an interference engine. I know that one poster said breaking your timing belt with an interference engine doesn't necessarily destroy the engine, but that's what I've always heard. I'd be interested in knowing more about that.

In addition, why would you make a car where the engine is destroyed, or even might be destroyed, if the timing belt were to break. In other words, what are the benefits to an interference engine that would outweigh that huge disadvantage?

I can't afford to replace it which is why I never have but I really hope my 08 holds up as well!

Anybody know what's in my car? I have no idea! lol
By then Toyota had switched to chains on their 4 cylinders.

My mom had a '85 Civic. Belt broke twice, wiped the valves both times.

My '84 and '91 Civics had belts. No problems.

The first engine to use a toothed rubber timing belt was the 230 cu. in. Pontiac Overhead Cam Six, which came out in 1966 in two versions. The base model had a single-barrel carb, simple intake and exhaust manifolds, and 8.0:1 compression. The Sprint model had a Quadrajet carb, more elaborate manifolds, and 10.5:1 compression. I had a '67 Sprint Firebird for a few years. No problems with the timing belt.
I saw one of those over the weekend!

My 1997 NSX uses a timing belt. Even that engine expects a TB at 90K miles.
Yep. And all of the owners had to waste $600 to change the timing belt. The J series engines are really nice ... except for the fact that if you don't waste $600 every 7 years it will self destruct.

I know a few people with these cars. Nice cars but they can't "afford" the timing belt change. Great, I'm sure they can afford the new engine because Honda is too cheap to put a proper chain on it.

If $600 is a ridiculous amount of money to you, you should probably not be owning/driving a vehicle, because you obviously cannot afford to buy insurance either.
I can afford the maintenance, but I chose to buy vehicles that are cheap to maintain. There's no reason for me to buy a vehicle that requires me to waste $600 every 7 or 8 years on something that should be lifetime.

If you think it's acceptable , that's fine.

I don't remember what he said but I knew it was too early for that chain to be replaced when it was mentioned. What he actually heard was a noise in the HVAC system but that noise didn't affect the operation of HVAC. I knew he was fishing for additional work that wasn't needed and I've never gone back there again; too bad for that MIDAS shop.

Where did you see it?

It's a '68. I think it's the base model, not the Sprint.

Wow, I do remember that engine. I don't that that many were made. It seemed very European at the time.

I don't think a Hyundai can generate enough torque to spin a belt or chain off a gear/pulley. Belts were for job security at dealerships. $600 is robbery.
Chain can't go bad but belts are rubber which wears/rots.

Think of the numbers of American V8s that have rolled around on the roads for decades and never have worries with timing chains. Many go 500K+ and still have the original timing chain; think big city taxi cab.

I always wanted gears back when in the days when I had my 69 Camaro but never got a round tuit.

Both my cars have chains now. I would avoid belts if possible. And its also better for resale, you can state that its a lower maintenance vehicle because of the chain.

I guess you never heard of the issues Pontiac had with their timing chains in the 60's and early 70's? Mechanics used to love them. 50k miles - another chain! How about AMC and the distributor/cam gear teeth getting chewed up? Had to use a "matched set" to get around that issue.

Well, the car is a '67 (note wing windows). I think that the air cleaner housing is a '68 or maybe from a '67 California car.
