Diagnostic Steps

Solution

1. Preparation

Tools Required: OBD-II scanner (if engine light is on), flashlight, UV light, oil pressure gauge, oil catch pan.
Safety Warnings: Ensure the engine is cool before starting. Wear gloves to protect your hands from oil.

2. Visual Inspection

Lift the vehicle using a jack and secure it with jack stands.
Place an oil catch pan under the oil pan area.
Check for any oil spots under the engine and along the sides of the oil pan.

3. Inspect Engine Bay

Open the hood and use a flashlight to look for oil leaks on the engine block, oil filter, and valve cover.
Wipe down any suspected areas with a clean rag to identify if new oil appears.

4. Check Oil Filter and Drain Plug

Using an appropriate wrench, check that the oil filter is tightened to the manufacturer’s specifications (typically hand-tight with an additional 3/4 turn).
Inspect the drain plug for tightness; torque it to the specified value (usually around 25 ft-lb, check your owner's manual).

5. Perform a Pressure Test

Connect an oil pressure gauge to the oil pressure sending unit.
Start the engine and observe the pressure reading; it should fall within the manufacturer's specified range.

6. Use UV Dye

If leaks are still not identified, add a small amount of UV dye to the engine oil.
Run the engine for a short period, then use a UV light to scan for fluorescent traces of oil.
