Do the valves get belt on a 1996 ford escort if the timing belt slips?

Yes, sometimes. How often? Don't know. I know of the belt braking on a 1997 4 cylinder. Replaced the belt and the car ran fine for another 6 months, then it broke a valve or piston ring (removed pieces via the spark plug hole). The mechanics charged over $400 to replace the belt. I don't know if they ran a compression test afterwards or not, but they should have. However, the belt is grooved and it would be hard for it to slip. I suppose it could jump a notch, but that's a guess for sure.
