what happens if the timed belt will cut of

WELL THERE IS ALWAYS A POSIBILITY OF VALVE BEING DAMAGE THAT IS NOT ALWAYS THE CASE FOR A JOB LIKE THIS PARTS AND LABOR WOULD BE 225.00 PLUS TAX!! IF ANY QUESTION CALL ME 305-899-0502 MIKE

never heard of a timing belt install costing as much as an engine. IF THE TIMING BELT IS BROKE and it is a single cam you probably dont have any valve damage, if you are very mechanical you can fix this your self you just have to have your crank at top dead center as well as your cam tdc on #1 cylander
