Solution

1. Preparation

Tools Required: OBD-II scanner, UV dye kit, UV light, basic hand tools (sockets, wrenches), oil catch pan.
Safety Warnings: Ensure the engine is cool before starting work. Wear gloves and safety glasses.

2. Inspect Oil Components

Remove Engine Covers: If necessary, remove any engine covers to access seals and gaskets.

3. Repair or Replace Faulty Components

Tighten or Replace: If the oil filter or drain plug is loose, tighten them. Replace any faulty components (gaskets, seals).
Clean Surfaces: If components are removed, clean the surfaces with a gasket scraper to ensure a proper seal.
Install New Gaskets: Apply RTV sealant if required, and install new gaskets as needed.
Reassemble: Reattach any components or covers removed during inspection.

4. Final Check
