Timing Belt destroyed engine

[jcwit]

Know all about cogged belts on milling machines, was a tool and Die maker for 25 years. Never had one of them break or shear teeth in my experience either.

Have had many cars with interference engines and timing belts, Escort, Chevette, Metro's, & Honda's, and now a KIA Rio. Always replaced belts at mfg. suggested intervals, usually 60,000 to 100,000 miles. Sometimes I had the tensioner replaced sometimes not, always went by my mechanics suggestions, he's never lead me wrong in 30 plus years of service.

You're saying your belt is not broken or any teeth sheared off? Mayhap you have the one that makes the rule true.

I should add, I also go by the mechanics recommendation as to whether to replace the water pump or not, and he hasn't missed yet.

A milling machine belt probably isn't subject to the heat and frequent RPM change like an automotive engine. Belt stretch may be a possibility, the tensioner is a spring type and not automatically adjustable unless you go in and readjust it. On the few engines i've dealt with that grenaded, the belts were all missing teeth on the belt. On the engines i've replaced timing belts on a maintenance basis, the belt is usually always cracked where the teeth meet the belt. I think it is a combo of a belt that could stand to be a bit wider, a lone broken tooth or teeth and belt stretch.

Just for the sake of adding more carnage pics (can't have enough of those right?).... Here you go:

That is probably one of the worst ones i've seen lol. At least #3 intake valves are still in decent shape lol

[mdocod]

Oh yea, it would definitely qualify for some around the water cooler time at the local garage. I've had several people look at it in amazement. This level of damage is hard to achieve.

A hole through every piston, 8 valves busted clean off, 6 more bent, 2 maybe only slightly bent?

Perhaps for the better because when I pulled the head the damage was severe enough to keep me laughing, which has probably helped keep my spirits up.

Hi everyone,

So i recently bought a 2001 Kia Rio as my first car at 110000km on it. I was not so surprised to see that the timing belt still had not been changed and am in a desperate scurry to change it.

It is now pushing 114,000km and still seems to be running except I when I accelerate past 50km the engine is making a noise and the car almost vibrates.

I am reading that I should replace the belt with a dayco belt and if so what size should I buy for it.

I am a very poor university student who hardly knows anything about cars and I really want to not spend a shit load of money but have my car run well for the next 3 to 4 years.

P.S - how long do Kia's live for mileage wise?


Oh and one more problem I have found is that the dash board flickers. I think a wire is loose.

Overall I have really enjoyed the car for the past couple of months.
If anyone was thinking of buying one, just make sure you get a mech check on the vehicle.

Being as you're a collage student I would think you could express yourself without vulgar language.

With that said, get the belt changed ASAP with either a Gates or a Dayco. Do not wait as if it breaks you've destroyed the engine.

Regarding the engine noise and vib. is your cel on? If so what are the codes? What kind of noise is it making?

[jayyded]

Sorry for my previous language, I am extremely frustrated and worried about my car.

The noise sounds like the engine is working really hard when i drive over 50kms/h. When you are looking into the car, the piece that is vibrating and making the sound is on the left hand side and under a little bit in a circluar encasement. I am pretty sure that is where the belt is.

Where can I buy a Gates or Dayco belt - and do I just say its for a 2001 Kia rio?

I also am curious to how long a Kia rio should last - I felt that I bought mine for a cheap price with low kms and want to keep it for a couple more years.

[jcwit]

Just did a quick search for auto parts, I'm not going to hunt everything down for you. Remember google is your friend, google auto parts.

As far as how long does a KIA last? Depends on how it is taken care of how it it is driven, ect., the same as with any vehicle. There used to be a fellow on another forum that claimed 300,000 miles so who knows. I would say its in the owners hands.

If your car is like mine the "piece" making the noise would be the A/C compresser, thats what is towards the bottom, the one above it is the power steering pump. You sure the water pump isn't doing it? Thats between the engine and the firewall.

Just got one of these in the yard. 2004 rio, 32000 actual miles timing belt failed, am now 1/2 way into it. This engine is a copy of the Mazda engine, that frankly was dependable and very trouble free. I checked the belt and it is hard and inflexible, a sign of HIGH heat which caused the damage and the separation of the teeth. Am starting to think the problem may be the engine compartment holding and containing the heat due to rubber sealing and insulation to limit the noise of the engine. I have seen wire insulation that is hard and brittle on other kias, it was under the plastic covers that hide the wires and have insulation for noise reduction and are used in part to "trim up" the engine interior. In this car there is rubber sealing both fenders and the fire wall, sealing and holding the heat in, engines run hotter than in the past to be more fuel effiecent than in the past. This may well be the problem here because the engine is strong and well designed and the belt appears to be equal to Mazda belts I've seen that easily run over 100,000 miles

Hi all,

I tend to agree with mdocod, in that the timing belt is not the root cause of every catastrophic valve timing failure described in this forum. I have a 2003 Rio which I bought with 65,000km on the clock. At the next scheduled service I had the timing belt replaced. with 125,000km on the clock the engine just stopped and seized while coming to a hault at an intersection while doing less than 20km/hr. Upon removing the head I noticed the following:

1. all exhaust valves broken
2. all inlet valves seemingly OK
3. timing belt in one piece, pliable with no cracking at the base of teeth and all teeth missing around the crank shaft pulley.

If it were the TB that failed first how is it that all of the exhaust valves in all cylinders are distroyed? Wouldn't TB failure result in the valve timing staying fixed in position while the crank turned over, resulting in only some cylinders with exhaust valves open to be crowned by the piston?

Also if were TB failure shouldn't it be a mix of both exhaust and intake valves damaged, since while one cylinder is exhausting another is intaking?

More likely in this case is that the belt has jumped a number of teeth, retarding the valve timing, resulting in the exhaust valves remaining open at TDC. Subsequent load generated by destroying the valves has stripped the TB.

Comments welcome

That happens to be waiting with a timing belt replacement. Do not look at it that manufacturers recommend every 90,000 - 120,000 miles. Timing belt change should be done every 60,000 miles. Breaking the timing belt is associated with the renovation of the engine. I know this from experience, because I once broke a timing belt.

[stackman2005]

i have a 2006 kia rio and it has 179,000 miles on it. we got brand new and the timing belt has never been changed. so how do you explain that. but after reading your post on here im thinking i might have it done. i want to drive this car atleast a couple more years.

[mellowde]

I've an 04 kia rio with the 1.6 l enginge and have 130,000 miles on it with no timing belt issues to date. I change the oil every 3000 miles regularly and do tune ups and injector cleans and the unit runs great. Only problem was a rear wheel bearing that was a bugger to repair properly. But i got past that with a manual.

Timing belt doesn't care how clean your oil is. You're living on borrowed time on the belt.
