It's possible, especially if you cranked the engine over a lot to try and start it. See your mechanic to find out for sure.

You have to remove the head to find out. If it didn't have any rattling noises when it happened and the engine spins freely, you may have a non-interference engine. An engine like this can have the valves open and the piston won't slam into them. If that's the case, just put a new timing belt in. Call a Honda dealer and ask if your Civic has such an engine.

With the CIVIC, the chances are about 50-50. It is classified an interference engine, but I have seen many cases where there was no damage. Merely replaced the belt and idler, along with the water pump, and away they went.
The only real means of telling is to either look down the cylinder spark plug holes at the tops of the pistons for signs of contact, (A bore-scope really helps here) or replace the belt and see if it will run.
Good Luck

I'd go with 50-50. I'd take out the spark plugs and slowly rotate the crank by hand and listen and feel for the pistons trying to strike the valve heads. If you meet and resistance, stop.
Good luck!

50-50 chance. if you did not try to start it after it broke you have a very good chance that they are not hurt at all. if you have been tinkering with it trying to get it started then you may have caused damage to the valves but not always!

Some of these small engines are of the type called -non interference and some are of course the other , interference type. On the non you'll be okay but not so on the other. Good luck! See your mechanic.
