They can. The only way to know for certain is to put a new belt on and run a compression test. If one or more cylinders don't build compression after you've properly installed a new timing belt, the piston kissed a valve. BTW, it doesn't take much to bend a valve beyond being usable.

Is a Mazda Protege 1.6L DOHC an interference engine?

As far as I'm aware the engine is identical to that used in the MX5, so I'd assume yes it is an interference engine ^^Actually, the engines have the same displacement but that is the only similarity. The blocks are different, the transmissions are different and the heads are totally different. The mx5 engine is a B6 and the protege 1.6l is a ZM or ZM-DE depending on whether or not it is european. That being said, the protege 1.6l engine is non-interference, meaning that if your timing is off or your timing belt skips or breaks, the valves will not come into contact at any point with the pistons (there are 4 cut-aways in the piston heads to prevent any contact with the valves)

Is a Mazda Protege engine noninterfering?

Depends on the year. The 2.0 DOHC in a 2001-2003 is said to be a valve interference engine, meaning the valves can become struck by the piston and bent if the timing belt breaks or another event that significantly alters the valve timing occurs.

Does a 94 Mazda Protege dx have a timing belt?

Yes. Every modern car has either a timing belt or a timing chain. Yours is a belt. They need to be changed every 96,000 Km. Your car is a non-interference engine, so if the belt breaks your car will not work, you'll have to buy a new belt, and get your timing redone, but your engine will not be toast; it'll work fine once a new timing belt is put on. On other less fortunate cars, they have interference engines. This means that the pistons and the valves occupy the same space at different times. The timing belt is what regulates this timing. If it breaks on that type of engine, the pistons smash into the valves bending them, thus rendering the engine useless. You should probably get it changed by a professional, as if you screw it up you will affect the performance and life of your engine greatly.
