Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect Engine Components

Sub-steps:
- Open the hood and visually inspect the valve cover gasket for signs of oil leakage.
- Use a flashlight to illuminate hard-to-see areas.
- Check the oil filter for tightness and inspect for any oil seeping around the edges.

3. Check Oil Drain Plug

Sub-steps:
- Place a drain pan under the oil pan.
- Using a socket wrench, carefully loosen the drain plug and check for oil seeping.
- Re-tighten the drain plug to the manufacturer's torque specification (typically around 30-40 ft-lbs).

4. Inspect Oil Pan

Sub-steps:
- If there are signs of leakage, clean the area around the oil pan with a degreaser.
- Inspect for cracks or damage to the oil pan. If damage is found, oil pan replacement may be necessary.

5. Use UV Dye for Detection

Sub-steps:
- Add UV dye to the engine oil.
- Run the engine for a short period to circulate the dye.
- Use a UV light to inspect for any glowing areas indicating leaks.
