Solution

1. Preparation

Gather tools and materials: oil catch pan, socket set, wrench set, new oil filter, new oil, and rags.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Drain the Oil

Place the oil catch pan underneath the oil pan.
Remove the oil drain plug using the appropriate socket.
Allow the oil to fully drain into the pan, then replace the drain plug and torque to manufacturer specifications (typically 25-30 ft-lbs).

3. Remove and Replace the Oil Filter

Locate the oil filter and use an oil filter wrench to remove it.
Apply a small amount of new oil to the rubber gasket of the new filter.
Install the new oil filter, tightening it by hand until snug.

4. Inspect and Replace Gaskets/Seals

If leaks are found at the valve cover, remove the valve cover by unscrewing the retaining bolts.
Replace the valve cover gasket with a new one, ensuring a proper fit and sealing.
Reinstall the valve cover and torque to manufacturer specifications.

5. Refill Engine Oil

Pour the recommended type and amount of new oil into the engine through the oil filler cap.
Start the engine and let it run for a few minutes, allowing the new oil to circulate.

6. Final Inspection

After the engine has run, check for any leaks around the oil filter and drain plug.
Use a clean rag to wipe any spilled oil from the engine bay.
