Solution

1. Preparation

Gather tools and materials: socket set, flashlight, rags, oil leak detection dye (optional), and UV light (if using dye).
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Clean the Engine

Use a degreaser and rags to clean the engine surfaces, particularly around suspected leak areas.
Allow the engine to dry completely to make it easier to spot fresh leaks.

3. Inspect Components

Oil Filter:
- Check for tightness; if loose, tighten it to the manufacturer's specifications.
- Inspect for any cracks or defects.
Oil Pan:
- Inspect the oil pan and gasket for cracks or signs of oil seeping.
- If damaged, prepare for a gasket replacement.

4. Check Gaskets and Seals

Inspect the valve cover gaskets and other seals:
- Look for signs of cracking, hardening, or oil leaks.
- If found, replace the gaskets/seals as needed.

5. Pressure Test (if necessary)

If leaks are still undetected, use an oil leak detection dye:
- Add the dye to the engine oil.
- Run the engine for a short period, then inspect with a UV light to identify the leak source.
