Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical hazards.

2. Identify the Leak Source

Sub-steps:
- Clean the engine area using a degreaser to remove old oil stains.
- Use a UV dye in the engine oil if necessary, and run the engine for 10-15 minutes.
- Inspect for fluorescent dye traces to pinpoint the leak source.

3. Repair the Leak

Sub-steps:
- If the leak is from the oil filter:
  - Remove the old oil filter using an oil filter wrench.
  - Apply a thin layer of engine oil to the rubber gasket of the new oil filter.
  - Install the new oil filter, tightening it to the manufacturer's specifications.
- If the leak is from the drain plug:
  - Use a socket wrench to remove the drain plug and inspect the gasket.
  - Replace the gasket if damaged and re-install the drain plug, tightening to the specified torque (typically around 20 lb-ft).
- If the leak is from gaskets or seals:
  - Drain the engine oil and remove components blocking access to the gasket (e.g., oil pan, valve covers).
  - Clean the mating surfaces thoroughly.
  - Install new gaskets or seals, ensuring proper alignment and fit.
  - Reassemble components and refill with the correct engine oil type.

4. Clean Up

Remove any oil spills from the engine bay and underneath the vehicle.
