Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety.

Tools Required:

Socket set
Torque wrench
Oil catch pan
UV leak detection kit (if needed)

2. Locate and Repair Oil Leak

Inspect Gaskets and Seals:
- Look closely at the valve cover gasket and oil pan gasket.
- If leaking, remove the old gasket and clean the surface.
- Install a new gasket and torque to manufacturer specifications (usually around 8-12 Nm for most gaskets).
Check Oil Filter:
- Tighten the oil filter using an oil filter wrench if it is loose.
- If damaged, remove the old filter, apply a thin coat of oil to the rubber gasket of the new filter, and install it.

3. Clean Engine Components

Clean any areas affected by oil buildup using a degreaser and cloth.
Ensure all surfaces are dry before starting the engine.

4. Replace Engine Oil (if necessary)

If the oil level is low or the oil is contaminated, drain the old oil using an oil catch pan.
Replace with the correct grade of engine oil as specified in the owner's manual.
Replace the oil filter again if it was previously leaking.

5. Reconnect Battery

Reconnect the battery terminals securely after completing the repairs.
