Solution

1. Preparation

Tools Required: OBD-II scanner, mechanic's stethoscope, socket set, torque wrench, feeler gauge.
Safety Warnings: Disconnect the battery before starting work on electrical components.

2. Change Engine Oil and Filter

Drain the oil:
- Place a drain pan under the oil pan.
- Remove the oil drain plug using a socket set, allowing the old oil to fully drain.
Replace the oil filter:
- Use an oil filter wrench to remove the old filter.
- Apply a thin layer of new oil on the rubber gasket of the new filter.
- Install the new filter by hand until snug, then tighten an additional 3/4 turn.
Refill with oil:
- Replace the drain plug and torque to manufacturer specifications.
- Add new oil through the oil filler cap, using the appropriate type and amount specified in the owner's manual.

3. Adjust Valve Clearance (if applicable)

Remove the valve cover:
- Disconnect any components obstructing access to the valve cover.
- Remove the bolts securing the valve cover and gently lift it off.
Measure and adjust clearance:
- Use a feeler gauge to measure the clearance between the rocker arm and valve stem.
- Adjust by loosening the rocker arm lock nut and turning the adjustment screw to achieve the specified clearance.
Reinstall the valve cover:
- Clean the mating surfaces and apply a new gasket if necessary.
- Reinstall the valve cover and torque the bolts to the manufacturer's specifications.
