Both. When it normally runs valves come very close to pistons. If belt breaks, any open valves will have come in contact with pistons and usually bend or break, but engine will free spin.

My wife's 2001 Hyundai sonata throw a timingbelt last night . did it hurt anything or can I just put a new timingbelt on it ? it's a 4 cyc. DOHC FI if this helps . Thanks for your input ..


it depends on sheer luck
Whether you have bent a piston rod or not.
I don't know how you work out if the piston rods are ok.
You may need a mechanic to assess if any damage has occurred.

Also the bearing may be worn out that the timing belt runs on.

On one of my cars I owned a Magna. I got the timing belt replaced well over the recommended 100,000 Km and all the bearings were worn out and the belt was close to breaking .

2000 hyundai accent timing belt broke. absolutely no noise when belt broke


No, you won't hear it, it will happen same instant as the belt breaking.
Try to find a head from a low mileage unit, if at all possible. Pull your head off first, and check the top of pistons for damage. If the pistons and lower end are alright-spin it around by hand several times and listen for noise- then go for the used head.

Timing marks hyundai excell


What year, and what engine?

If it broke I wouldn't bother replacing it until I confirmed that the valves are NOT bent! Usually when the belt brakes on a Hyundai the piston will hit a valve or two and sometimes the valve will actually poke a hole in the piston.

98 Dodge Caravan 2.4 DOHC, broken timing belt, what is the likelyhood that some valves were bent?


Its very likely that some of the valves are bent, usually on these vehicles when the timing belt fails the pistons contact the valves but does not cause cylinder head damage. I remove all of the valves and roll them on a flat surface to see if they "wobble", some of the bends are very minor and are difficult to see with the naked eye, but can cause serious driveability issues.

Are the V6 engines Free spinning?


Hi Lukegerny,
No,the V6 engine is not free spinning. If the timing chain breaks, leaving the valves open as the piston moves through its travel,there will be damage to the valves.How much damage will depend on speed of engine and length of time it ran. You can perform a leak down test to check the condition of the pistons and valves. It will tell you if the valves are not sealing,without having to take it apart. Thanks,Chuck.

Timing belt snapped


hi from uk the cambelt timing marks for accent 1.3/1.5 petrol are as follows= the cam cog has a hole drilling between the outer toothed and the central securing bolt this hole at TDC number 1 cyl is at top central and lines up with a V cut in the cyl head at rear of cog ? the crank cog at TDC number 1 cyl is a pop mark on both the cog and on thefront face of engine quite noticable ! these line up and are at approx 12 -30 pm when viewed fit new belt from crankcog in anticlockwise ie crank then cam then tensioner HOWEVER! if you are considering just replacing belt and tensioner ? be warned this engine is an interferance engine that is to say if belt fails whilst driving there may/will most probably be damage to the valves (bent) due to contact with pistons so would advise caution and suggest compression test all cyls after fitting new belt and tensioner and before rebuild completely once valves have bent they will not contact pistons again but you will have serious missfire/s and probably back fire up inlet manifold coupled with failing to start if engine is high milage ? consider removal of cyl head and check? de coke and replace damaged or best all valves then engine will have improved performance and more milesin future hope this helps

Will a broken timing belt and water pump require replacement of engine head valves 1 and 3?


If this is 2.0 liter duel over head cam than engine damage most likely will happen if the timing belt brakes sorry about the bad news .

1998 kia sportage. changed timing belt. now no compression.


WOW - DID THE BELT BREAK WHILE IT WAS RUNNING IF SO THE VALVES ARE BEND THATS WHY YOU HAVE NO COMPRESSION.
IF YOU HAD THE BELT REPLACED AND THEY DON'T HAVE THE TIMING MARKS RIGHT YOU CAN STILL BEND THE VALVES.
9 TIMES OUT OF 10 THE DAMAGE IS JUST TO THE VALVES AND NOT THE HEAD OR ENGINE. BUT IF YOU HAVE TO PULL THE HEAD MY ADVISE IS TO HAVE THE HEAD CHECKED FOR CNY CRACKS

Does a Hyundai 2002 1.6L DOHC have a timing belt or chain? If it's a chain, does it need to be replaced?


If you have an Accent which I believe that you do, it has a belt which needs to be changed every 60-80k miles. This vehicle has what is called an interference engine which basically means that if the belt breaks, the engine will continue to turn BUT the camshaft stops. If any of the valves are open the piston will slam into the open valve (interfere) and you will be looking at a new engine. I would recommend changing the water pump at the same time as well as the tensioner. I would also have the pulleys inspected by a professional mechanic and replaced as needed. If you just change the belt and the tensioner or the pulleys are weak then you can have premature breakage.
