Hearing rattling or ticking from your Chevrolet Impala’s engine—especially at idle or startup? This often indicates worn timing chain components or reduced oil flow. Extended oil change intervals and frequent short trips accelerate wear. Haynes provides comprehensive repair coverage, including torque settings, component diagrams, and step-by-step photos to help you diagnose accurately and prevent major timing system failures.
