Ouch. I was just thinking (reading the first post) that it was timing chain. If nothing internal is messed up and no valves are bent, they should be able to bring her to top dead center, put on the new chain and you should be good to go. But they may pull the motor all together and put in a new one just because it'd be a pain to pull the motor apart to check the internals.
