Timing chain or belt
If timing chain broke on 2007 93 2.0tu Saab
but wasn't driving is motor shot
Even trying to start the engine with the timing chain broke, will as a minimum, bend valve stems, (if you are lucky), but in all likelihood, piston crowns will be wrecked, cylinder head sicker than a sick thing and generally speaking the answer to your question is a definite "yes". Expensive...ouch !
