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.
