To detect a bad timing chain, listen for unusual noises such as rattling or slapping sounds coming from the engine, especially during startup. Check for engine misfires, rough idling, or poor acceleration, which may indicate timing issues. Additionally, inspect for oil leaks near the timing chain cover or check the timing chain tensioner for wear. If you suspect problems, a professional mechanic can perform a more thorough diagnosis, often involving checking the timing alignment.
