Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off and cool.
Disconnect the battery to ensure safety during repairs.

2. Inspect Engine Oil

Remove the engine oil dipstick and check the level; top off or change oil if necessary.
If oil is dirty, perform an oil change.
- Sub-steps:
  - Drain the old oil using a socket set to remove the oil drain plug.
  - Replace the oil filter using an oil filter wrench.
  - Refill with the manufacturer-recommended oil type and quantity.

3. Check Engine Mounts

Visually inspect engine mounts for cracks or wear.
Replace any damaged mounts:
- Sub-steps:
  - Support the engine with a jack and a block of wood.
  - Remove the bolts securing the mount using a socket set.
  - Replace the mount with a new one and torque bolts to manufacturer specifications.

4. Inspect Timing Belt/Chain

If the noise is suspected to originate from the timing belt/chain:
- Sub-steps:
  - Remove any covers obstructing access to the timing components.
  - Check for wear, slack, or alignment issues.
  - Replace the timing belt/chain if necessary, following the service manual for proper installation and torque specifications.

5. Reassemble and Reconnect

Reinstall any components or covers removed during the inspection.
Reconnect the battery and ensure all tools are removed from the engine bay.
