I know of 2000 Focus 2.0 liter w/110k that the timing belt broke on and is for sale for cheap. I don't mind doing a belt and other minor things but are these truly non-interference engines? I'm not into rebuilding or swapping the engine/drive train. But a belt and tension, I'll get my hands dirty on if there is a high likelihood the belt is the primary problem. Can I crank the engine and tell by the sounds if there is more extensive damage? Check plugs? Other clues to look for ? Love to hear from others who have experience in this situation.
