- Loose or worn engine mounts: The engine mounts are responsible for holding the engine in place and absorbing vibrations. If they are loose or worn, they can cause the engine to vibrate excessively, which can lead to a rattling noise.
- Bad spark plugs: Worn or dirty spark plugs can cause the engine to misfire, which can also lead to a rattling noise.
- Loose or damaged exhaust system: A loose or damaged exhaust system can also cause a rattling noise.
- Worn or damaged timing chain. The timing chain synchronises the movement of the pistons and the valves, and if it is worn or damaged, it can cause a rattling noise.
To determine the exact cause of the rattling noise in your Honda Accord, it is best to take it to a qualified mechanic for diagnosis and repair.
