If it snapped at idle you could try timing and a new belt, but if you were motoring its likely to have f*cked shit up. Dont do a Chris and start turning it over lol.
Edit: Forgot to put how f*cking gay that is, how can it snap 9 months after it was done!? Did they use asda smart price elastic bands or something!
