What happens if timing belt snaps while driving?

If a timing belt breaks while driving in an interference engine, the camshaft stops turning leaving some of the engine valves in the open position. This may result in a heavy damage to the engine with broken or bent valves, damaged pistons and, possibly, destroyed cylinder head and block.

Can a broken timing belt ruin an engine?

Can a broken timing chain lock up an engine?

A timing chain is supposed to last the life of a vehicle, within reason. But if it breaks, the pistons will come up at the wrong time and crush a bunch of the valves, leaving the crankshaft unable to turn. That would lock up the engine, just as if you had run out of oil and melted the crankshaft to the bearings.

What can cause a timing belt to break?

With the heat and friction inside the engine, the rubber material will become worn with age and miles. Rubber teeth may wear down and no longer be able to grip the gears. This often results in a slip of the timing belt and potential damage to the engine. The timing belt may also begin to crack under stress.
