Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench
Ensure the vehicle is parked on a level surface.
Disconnect the battery to avoid electrical shorts.

2. Oil Change (if oil condition is poor)

Sub-steps:
1. Place a drain pan under the oil pan.
2. Remove the oil drain plug and allow the old oil to fully drain.
3. Replace the oil filter using an oil filter wrench.
4. Install a new oil filter, ensuring it is properly tightened.
5. Replace the drain plug and torque it to the manufacturer’s specification.
6. Refill the engine with the appropriate type and amount of oil.

3. Valve Adjustment (if applicable)

Sub-steps:
1. Remove the valve cover to access the valvetrain components.
2. Check the clearance of the rocker arms or lifters.
3. Adjust the valve clearance according to manufacturer specifications.
4. Reinstall the valve cover with a new gasket to prevent leaks.

4. Timing Chain/Belt Inspection (if needed)

Sub-steps:
1. Remove any necessary components to access the timing chain or belt.
2. Inspect the timing chain or belt for wear, tension, and alignment.
3. Replace the timing chain or belt if it shows signs of wear or damage.
4. Reassemble the components, ensuring all bolts are torqued to specifications.
