That happened to me. If your timing belt is loose it won't be as bad as you think. Just some bent valves. Probably won't even have to get a new engine. Just rebuild the head or a new one. It is easier to get a new head. If you look around they are not to bad for $$$ and cheaper then getting it rebuilt.
I know how parents goes, I have 2 dead cars getting fixed in their driveway right now.
