Solution

1. Preparation

Tools Required: Jack and jack stands, oil catch pan, socket set, torque wrench, engine degreaser, clean rags.
Safety Warnings: Ensure the engine is cool before starting work, and disconnect the battery to prevent electrical issues.

2. Locate the Leak Source

Sub-steps:
- Use a flashlight to inspect areas identified in the diagnostic steps.
- Clean any oily surfaces with engine degreaser to help pinpoint the leak.

3. Replace Gaskets or Seals

Sub-steps:
- If the valve cover gasket is leaking, remove the valve cover by loosening bolts (torque specifications: typically around 10 Nm).
- Remove the old gasket and clean the mating surfaces.
- Install the new gasket and reattach the valve cover, tightening to specifications.
- For oil pan leaks, drain the engine oil, remove the oil pan bolts, and replace the gasket, then reassemble the oil pan, ensuring proper torque.

4. Replace Oil Filter (if necessary)

Sub-steps:
- Using an oil filter wrench, remove the old oil filter.
- Apply a small amount of fresh oil to the rubber gasket of the new filter.
- Install the new oil filter by hand until snug, then tighten it according to the manufacturer's specifications.

5. Refill Engine Oil

Sub-steps:
- Replace the drain plug and torque it to specifications (typically around 25 Nm).
- Refill the engine oil using the recommended type and quantity (check owner’s manual for specifics).

6. Test for Leaks

Sub-steps:
- Start the engine and allow it to reach operating temperature.
- Inspect the previously identified leak areas for any signs of new oil leakage.
