Solution

1. Preparation

Gather Tools: OBD-II scanner, socket set, mechanic's stethoscope, torque wrench.
Safety Precautions: Disconnect the battery before starting any work on the engine.

2. Change Engine Oil

Sub-steps:
1. Drain the old engine oil by removing the oil drain plug using a socket wrench.
2. Replace the oil filter using an oil filter wrench.

Sub-steps:
1. Remove the engine cover to access the valve assembly.
2. Use a feeler gauge to measure the clearance and adjust as necessary by loosening the rocker arm bolts and repositioning them.
3. Re-torque the bolts to the manufacturer's specifications (usually around 16-22 ft-lbs).
4. Reinstall the engine cover.

4. Inspect and Replace Timing Components (if necessary)

Sub-steps:
1. Remove any components obstructing access to the timing chain/belt.
2. Inspect for wear or damage; replace if necessary.
3. Align the timing marks and replace with a new timing chain/belt, ensuring proper tension.
4. Reassemble all components in reverse order.

5. Check Accessory Belts
