If your timing belt tension is lost, it can lead to the timing belt slipping or breaking, which may cause the engine's pistons to collide with the valves. Symptoms of bent valves include a significant drop in engine performance, unusual noises from the engine (like tapping or grinding), and difficulty starting the engine. Additionally, a compression test may reveal low or inconsistent cylinder pressure, indicating that the valves are not sealing properly. Visual inspection during a tear-down can confirm bent valves.
