What happens when the timing belt cracks at 2.3E

Hello together, have a question: what happens with the 2.3E 5-cylinder when the timing belt is tearing during the ride? Then touch the pistons and valves and there is a lot of mud or you just stay lying down? Would I be very interested, because I don’t know exactly when my used the timing belt was made the last time. Thanks and greeting H.-P.
