Typically, when a belt fails due to old age or wear, the engine cranks at about twice its normal speed and sounds very 'light.' This is because there is no compression. The cam is driven by the crankshaft via the timing belt which is, of course, broken. Belt does not drive the cam, cam does not open/close the valves, and so compression is effectively zero.

You said that you tried to start the car today and "nothing happened." Did the starter motor engage? If the starter is not engaging, then you have a seizure somewhere. Given that the belt is missing teeth at the crank pulley which turns freely, whereas the camshaft does not, I think it is safe to assume that the cam is seized - IF the starter is not enaging. Otherwise, you just need to install a new belt. If you're at 220k and the belt has been replaced at 50k mile intervals in the past, then you are 20k miles past the change interval for this belt.

Clearances in the B230F/B230FT are such that the valves and pistons could never possibly come into contact with each other. So barring a seized cam, a new belt should get you back on the road again.

If the cam is the problem,
