What happens when a timing belt breaks on an interference engine?

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.

Does a interference engine have a timing belt or chain?

Interference engines rely on timing gears, chains, or belts to prevent the piston from striking the valves by ensuring that the valves are closed when the piston is near top dead center.

What would be a common timing belt replacement interval?
