Yes most of the time if your timing chain breaks the valves are junked especially motors with dual overhead cams with 24 valves like the 3.1

SOURCE: if the timing belt breaks does this shear or bend the valves on a

All Daewoo Engines are interference fit Engines. Which means that if the timing belt rips while the engine is running the pistons will hit and bend the valves and you will have to get new valves and possibly a new cylinder head. Worst case scenario you will also have to get a new engine block if for some reason chunks or pieces of valve, piston or cylinder head damaged the cylinder bore and cracked the block while things were moving around. Daewoo Timing belts are recommended to be replaced at 60,000 miles but it is best to replace them before 60k as some people have had their timing belts break on them as soon as 61,000 miles.

Does the 1999 chevrolet cavalier have a timing belt or a timing chain and if it breaks do the valves hit the pistons.


The 99 cavalier 2.2 and 2.4 both use a timing chain and yes, if the chain breaks it can damage valves. If the engine still cranks over you can remove the upper coil module cover, remove a spark plug, roll the engine over and see if compression builds. If the engine does not crank over, the broken chain will prevent the engine from turning.

What does the car do when the timing belt goes out


The 2001 Cavalier does not have a timing belt....it has a chain. That being said, the tensioner for the timing chain is a common failure item. If the tensioner fails while the car is at speed, the timing chain will jump across the crankshaft teeth, putting the crankshaft and camshaft out of synchronization. This will cause the car to immediately shutdown, the pistons in the engine will come up and hit and bend the valves, resulting in internal damage to the engine.

If the chain broke while the engine was running, and I presume it did, it is possible that you may have damaged the valves. When the chain breaks the cam shaft stops moving and the valves stay in their last position. The pistons continue to move until the engine comes to a stop. An open valve can be hit by a piston, sometimes breaking the valve or just bending the shaft. Also you have to be sure the new chain has the cam shaft and crank shaft properly timed. As I understand that that engine does not have timing marks on the chain sprockets. To test for damaged valves, remove the spark plugs and test the compression in each cylinder by cranking the engine while holding the compression gage in the spark plug hole. All the cylinder should have the same pressure within about 15 psi. A cylinder with damaged valves will not have any compression pressure. If you are unsure about the valve timing check into how that engine is timed. I don't have that information but if is out of time it has a very major effect on the engine performance and idle. I hope this gives you a place to start looking for the cause of the mis. Good luck.

Thanks for using FixYa.

Yes its a big fault if the timing belt breaks whilst the engine is running you could need a few new valves and possibly a new piston or two as well

If it broke while being started you more than likely have very little piston or valve damage even if it is an interference engine which I am not sure of. I have no idea what they mean by belt rollers when talking about the cam chain. It is a chain not a belt. You should be able to remove all spark plugs then spin the engine over with the starter an check the compression. If the compression is good then you more than likely have no serious damage. At that point all you can do is replace the cam chain and see what you then have. Once you get this fixed, sell the car.

2oo2 cavalier timing chain broke need to know how to fix it??


With a new motor most likley. When a timing chains break pistons tend to collide with valves which can punch holes in the pistons or bend/ break valves. Usually at this point it is more economical to replace the engine than to actually fix it.

What did you check as far as timing chain etc goes? Did you confirm all sprockets are aligned properly & crank, cams etc turning as they should?
