Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and allow the engine to cool down.
Disconnect the negative terminal of the battery for safety.

2. Inspect and Clean

Tools Required: Clean rags, cleaning solvent
Clean any visible oil from the engine components to identify the source of the leak.
Use a flashlight to inspect the area thoroughly.

3. Replace Gaskets or Seals

Remove the components covering the valve cover or oil pan (if necessary).
Carefully scrape off the old gasket material from the mating surfaces.
Install new gaskets or seals, ensuring they are positioned correctly.
Reassemble components and torque bolts to manufacturer specifications.

4. Fix Leaks

Tools Required: Wrench set, oil filter wrench
If the oil filter is leaking, replace it with a new one.
