Ok guys heres a little history first, my timing belt snaps and i replace the timing belt, pulley, water pump and all belts. Of coarse the timing belt snapping resulted in bent valves. I drive the car with bent valves and it shuts off on me again while driving. So i tow my car to the shop and they tell me my engine is done. My question is, can driving with bent valves cause more damage or possibly destroy the engine??
