- Use a jack to support the engine slightly, then replace any damaged mounts.
Inspect the Timing Chain/Belt:
- If noise persists, check the timing chain/belt for wear or misalignment.
- Remove any necessary covers according to the service manual.
- Replace if worn or if there is excessive slack.

3. Address Exhaust Issues

Inspect Exhaust System:
- Check for any loose connections, rust, or holes in the exhaust system.
