Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Safety goggles and gloves are recommended.

2. Identify the Source of the Leak

Tools Required: Flashlight, OBD-II scanner
Inspect the oil filter and oil drain plug for signs of leakage. Tighten if loose.
Check the valve cover gasket for any signs of oil seepage.
Examine the oil pan for cracks or damage.

3. Repair or Replace Affected Components

Tools Required: Socket set, torque wrench, new gaskets or seals
If the oil filter is leaking, remove it using an oil filter wrench and replace it with a new one.
For a leaking oil drain plug, replace the washer or the plug itself if damaged; torque to manufacturer's specification (typically around 25 ft-lbs).
If the valve cover gasket is leaking, remove the valve cover and replace the gasket. Clean the mating surfaces before reinstallation.

4. Refill Engine Oil

Tools Required: Oil funnel, new engine oil (refer to the owner's manual for specifications)
After repairs, refill the engine oil to the appropriate level using the correct type of oil.

5. Final Checks

Start the engine and let it run for a few minutes while monitoring for leaks.
Recheck the oil level and top off if necessary.
