Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather necessary tools and materials, including a ratchet set, UV dye, and UV light.

2. Inspect Oil Drain Plug and Oil Filter

Sub-steps:
1. Oil Drain Plug: Using a socket wrench, carefully inspect the oil drain plug for tightness. If loose, tighten it to the manufacturer's torque specification (typically around 20-25 ft-lbs).
2. Oil Filter: Check the oil filter for any signs of leaks. If it appears damaged or improperly seated, replace the oil filter.

3. Inspect Gaskets and Seals

Sub-steps:
1. Remove any necessary engine covers for access.
2. Carefully examine the valve cover gasket and oil pan gasket for cracks or wear.
3. Replace any worn gaskets if necessary, ensuring the surfaces are clean before installation.

4. Use UV Dye for Leaks

Sub-steps:
1. Add the recommended amount of UV dye to the engine oil.
2. Run the engine for approximately 10-15 minutes to allow the dye to circulate.
3. Use a UV light to inspect the engine and surrounding areas for any glowing signs of oil leaks.
