It depends on the design of the engine. Some engines are called "interference engines," which means that the way the combustion chambers are designed in that particular engine, if the valves happen to be open when the piston reaches that top of it's stroke, they would collide resulting in severe engine damage. The reason such engines are designed that way is to get the most performance out of the engine because the design makes it possible to have a smaller combustion chamber, thus higher compression. A "non-interference engine" has more space in the combustion chamber and the valves are recessed so that even if the valve happens to be open when the piston reaches the top of it's stroke, the two will not collide. If an engine is running in time, valves and pistons will never collide no matter what type of engine you have and as long as the timing belt does not break. However, when the timing belt breaks, there is nothing to keep the camshaft and the crankshaft running in time with each other. To find out if your engine would have been damaged by a broken timing belt, ask a technician if your's is an interference engine or a non-interference engine. Sometimes even the parts dealers know this information on some engines.
What else can I help you with?
What damage to engine when a timing belt fails?
On an interference engine the pistons can hit the valves. That will cause severe internal engine damage.
Is the 2001 Dodge Neon an interference engine?
Yes, internal engine damage can occur if the timing belt breaks.
Will a failed timing belt in a 1990 Eclipse that lost power and rolled to a stop cause serious engine damage to the point of needing to replace the engine?
The 1.8L is not an interference engine, so you should not have internal damage. The 2.0L is an interference engine. Internal engine damage is likely.
What happens to an engine when the timing belt snaps?
On an interference engine the pistons will hit the valves and cause severe internal engine damage.
What are symptoms of a bad timing belt in a Chrysler PT Cruiser?
No start, internal engine damage.
Does a car stop when timing belt breaks?
Yes, when the belt breaks the engine will not run. In addition you will have internal engine damage if the engine was an interference engine.
Will the valves bend if the timing chain was set wrong?
If the engine is an interference engine, yes, you can have internal engine damage if the belt is installed incorrectly.
1991 mercury capri timing belt broke does this ruin engine?
If the timing belt breaks on any engine the damage to the engine is usually very bad.
what happens if your timing belts is broken?
Car wont run & on interference engines there will be serious internal engine damage.
What happens to a car when the timing belt fails?
It depends if the engine is an interference engine. On an interference engine the positions will hit the valves and severe internal engine damage results.
What will happen to your 300zx if the timing belt breaks?
On older 300ZX's equipped with a timing belt it will cause internal engine damage if the belt breaks as they are interference engines.
If timing belt snaps on 2.5 transit diesel does this damage the valves?
If the timing belt snaps on a 2.5 Transit diesel, a secondary issue may be valve damage. When the timing of the engine is off, it throws the internal components out of whack.
