Customer Question

I have a 2003 i35 with 64k miles. It needed a water pump and I had it replaced. Once the repair done I drove the car no more than 10 miles and back home. The next day the car would not start. I had it towed back to my mechanic and two days later he tell me the valves and overhead cam are bent! What could have gone wrong?

The water pump on your car is driven by the timing belt. With that said if the timing belt breaks or slips the engine will go out of time. This will result in it not starting and bending valves.
More then likely when the water pump was installed the timing belt was not adjusted properly. When you went to crank it the belt slipped.
I have seen this happen quite often, and just as you describe.
