    If the timing belt broke, and you have no compression, it means the pistons smashed into the valves... you might have to rebuild the head and replace the bent/broken valves.

    Yeah did the belt brake?
    If the belt broke you have some bent valves.

    Did you use the cam locking tool???
    If the belt didnt brake and you DID NOT use the tool the timing may be off.

    yes - get a compression gage and an extension (needed to reach into the sparkplug holes), and turn over the engine. you won't hurt it worse than it is. iirc, compression should be in the 165 to 195 psi range on each cylinder.

    if the timing belt broke, chances are you have several bent exhaust valves, and the possibility of few bent intake valves. hopefully, there is no piston damage.

    If the timing belt while the engine was running, OR if you attempted to start the engine with a broken belt, then you absolutely, for certain, have at least a few bent valves in the heads. The good (for you) thing is that the valves are so soft that they probably didn't damage the pistons. I'll say with 99% certainty that you have bent valves.
