Solution

1. Preparation

Gather tools and materials: rags, oil catch pan, socket set, torque wrench, new gaskets or seals, and a replacement oil filter if needed.
Ensure the engine is cool and the vehicle is parked on a level surface.

2. Clean Up Oil Residue

Use rags to clean any visible oil spills in the engine bay. This will help in identifying new leaks post-repair.
Place the oil catch pan under the vehicle to catch any dripping oil.

3. Replace Worn Gaskets or Seals

3.1 Remove the affected components: If the oil leak is from a gasket or seal (like the valve cover gasket or oil pan gasket), remove the necessary components to access them.
3.2 Clean the surface: Use a scraper or gasket remover to clean the mating surfaces of any old gasket material.
3.3 Install new gasket: Place the new gasket in position, ensuring it is seated correctly.
3.4 Reassemble components: Reattach the components, following manufacturer torque specifications to avoid leaks.

4. Replace Oil Filter (if necessary)

4.1 Drain the oil: Use the oil catch pan to drain any remaining oil from the engine.
4.2 Remove the old oil filter: Use an oil filter wrench to loosen and remove the existing filter.
4.3 Install the new oil filter: Apply a small amount of new oil to the gasket of the new filter, then hand-tighten it in place.
4.4 Refill engine oil: Pour the correct type and amount of engine oil into the engine.

5. Final Inspection

Start the engine and let it run for a few minutes, checking for leaks around the newly installed components.
Monitor the oil level again and ensure it is within the recommended range.
