Hey, the engine was running fine before i bent the valves on accident, by changing the timing belt. The car was stumbling and running bad, with no power at all when driving but there was no ticking. So i took of the head, had a machining shop change the valves and machine the head, do a vaccum test, put everything back fire the car and there is some ticking, that is pretty loud. Do you guys know what it could be?
