Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, oil catch pan, clean rags, and new gaskets/filters if necessary.
Ensure the vehicle is parked on a level surface and the engine is cool to prevent burns.

2. Identify and Fix Oil Leaks

Locate Leak Source: Use a flashlight to examine the engine bay and undercarriage for oil stains.
Tighten Loose Components: If any bolts or fittings are loose, tighten them to specified torque values.
Replace Faulty Gaskets:
- Remove the old valve cover gasket or oil pan gasket using a socket set.
- Clean the mating surfaces with a clean rag and gasket scraper.
- Install the new gasket, ensuring proper alignment.
Replace Oil Filter (if leaking):
- Place the oil catch pan under the oil filter.
- Remove the old filter using an oil filter wrench.
- Lubricate the O-ring of the new filter with a small amount of oil, then install it hand-tight.

3. Refill Engine Oil

Check Oil Level: If oil was lost during inspection, refill using the manufacturer-recommended oil type and viscosity.
Check for Leaks Again: Start the engine and let it run for a few minutes while checking for any new leaks.
