Solution

1. Preparation

Gather tools and materials:
- Oil catch pan
- Socket set
- Torque wrench
- Replacement gaskets or seals (if needed)
- New oil and oil filter (if changing)
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Remove Old Oil and Filter

Place an oil catch pan under the oil pan.
Remove the oil drain plug using the appropriate socket and allow the old oil to drain completely.
Remove the old oil filter using an oil filter wrench. Lubricate the rubber O-ring of the new filter with new oil before installation.

3. Inspect and Replace Seals/Gaskets

If oil is leaking from the valve cover gasket, loosen the bolts securing the valve cover and remove it carefully.
Inspect the old gasket for wear or damage and clean the mating surfaces thoroughly.
Install a new valve cover gasket and reassemble the valve cover, tightening the bolts to the manufacturer's specifications using a torque wrench.
If the oil pan gasket is leaking, follow a similar procedure to remove the oil pan, replace the gasket, and reassemble.

4. Refill Oil

Replace the oil drain plug and tighten it securely.
Install the new oil filter.
Refill the engine with the recommended type and amount of new oil.
