I have a 1994 Toyota Tercel with 170,000 miles the timing belt broke.

Your car, unfortunately, is listed as an interference engine so valve damage could be an issue but there is hope! If the T/belt broke when the vehicle was idling in gear or something like that damage could have been avoided. If the T/belt broke while cruising at 60mph not so good. Is this some thing that your going to tackle yourself? If so let me know I'll give you some tips on how to tell if damage was done or not. Cheer's, Evan
