If it is a CRX then I believe it is an interference engine and yes you could have possibly damaged your valves pistons or both with the timing belt failure. The only way to know for sure is to do a compression test on the vehicle assuming it will still turn over after you fix the timing belt

In almost every instance yes, there will be damage to the valves and possibly the piston.

The Simple answer is yes the piston its the valves and possibly damage the pistons

The failure of the 2004 Kia 2.4 liter timing belt can cause severe damage to the piston heads and the valves. The timing belt failure can ruin the engine.

Yes valves can bend if the timing belt breaks.Yes valves can bend if the timing belt breaks.

Almost always you will have bent valves and possible a busted piston. This is an interference engine.

In an engine, the piston's go up and the valve's that are adjacent to that piston go up. When the piston goes down the adjacent valves go down. This is achieved by the timing belt or chain and the engine timing being set correctly. If the belt or chain breaks, the pistons still go up and down, but the valve's stop moving. On a non clearance engine, the piston will go up and hit the valves, resulting in bent valves and a now needed head job. In a clearance engine, the top of the piston has an inset cut into it that is just enough room to avoid hitting the valves.

No, it is interference. Valves can bend if the timing belt breaks.No, it is interference. Valves can bend if the timing belt breaks.

Answer: yes it could have bent some valves or damaged a piston with one or more of the valves( could have punched hole in piston or smashed piston so hard that it damaged a bearing)

yes they could but it depends on the position of the cam. the valves could be stuck in an open postion and then the piston comes up and could strike the valve. this is a bad scenario and i hope it doesnt happen to you

the ZETEC engine used in the 1999 ZX2 is a non-interference engine. This means that the pistons will not contact the valves when the timing belt breaks. Because of this, the valves will not be bad if the timing belt breaks

yes, valves can bend if the timing belt breaks.yes, valves can bend if the timing belt breaks.

By interference, if you are referring to the valves. The 1.8 liter is a non interference engine. If the timing belt brakes, then the valves do not interfere with the piston. They do not try and occupy the same space. The 1.9 liter engine is an interference engine. If the timing belt breaks then the valves will occupy the same space as the piston and they will hit each other.

Also known as a interference engine, A zero tolerance engine is an engine that would damage the valves and likely the pistons without correct timing. This would occur because the valves and piston have the ability to come into contact with each other. With correct timing, this is not an issue because the piston travels away from the valves as they travel into the cylinder. When timing is lost, the piston could travel toward the valves as the valves enter the cylinder, resulting in severe damage to both. This is not an issue in a non interference engine because the piston and valves will not contact each other if timing was lost.

Just a guess, as I don't own one of these; VW engines are minimal or zero-clearance, meaning that the valves will hit the top of the piston if they aren't working correctly. If the timing belt (which it tied in with the valve operation) breaks, some valves may be stuck in the open position, and they could be clobbered by the piston. If the timing belt was recently replaced, they might not have correctly timed the valves.

It can if the pistons hit the valves while they are open. The timing chain ensures that when the piston is at the op of it's storke the valves are closed. When the chain breaks the cam stops turning allowing the valves to open and close so if the piston is still trying to travel up in the cyclinder with the valves open it will hit them and bend or break them. Also trying to start the engine with the timing change broken can have the exact same result.

Luckily in the Geo the valves never travel down far enough for the piston to hit it so even with the timing belt broken its safe you can crank the car over til your blue in the face with out hurting anything.

valve timing not right try again ,alternitivly remove both crank and camshaft pulleys and check that woodruff keys have not sheered.

If the timing belt breaks, the valves get bent immediately.

Replace the timing belt and pray that you dont have bent valves.

The valves can be bent when the timing belt breaks.

First off the 4.7L uses a timing chain, not a belt. Second, it could bend valves if the chain breaks.

It refers to an engine where the area occupied by the valves when they are open is occupied by the piston when the valves are closed. If the timing belt lets go while the engine is running the piston will smash the open valves doing loads of damage.

yes, if the timing belt breaks the pistons can hit the valves causeing the valves to bend, or causeing a hole in the piston(s) eather way the engine would need to be completely rebuilt. the same damage could be caused by trying to start the engine without the timing belt intact,
