Solution

1. Preparation

Gather all necessary tools and parts. Ensure the vehicle is parked on a level surface.
Disconnect the vehicle’s battery to prevent any electrical accidents during the repair.

2. Identify Leak Source

Sub-steps:
- Use a clean cloth to wipe any oil residue from the suspected leak areas.
- If using UV dye, add it to the engine oil and run the engine for a few minutes, then inspect under UV light to pinpoint the leak.

3. Repair Oil Leak

Sub-steps:
- If the leak is from the oil filter, replace it:
  - Use an oil filter wrench to remove the old filter.
  - Apply a thin layer of oil to the gasket of the new filter and install it by hand, tightening it according to manufacturer specifications.
- For leaks at the oil drain plug:
  - Use a socket to remove the drain plug, inspect the washer, and replace if damaged.
  - Reinstall the drain plug and torque to the manufacturer’s specifications (typically around 20-25 ft-lbs).
- For more serious leaks (like from the oil pan or valve cover):
  - Remove the affected components, clean the mating surfaces, and apply new gasket material or replace the gasket as needed.
  - Reassemble and torque bolts to specified values.

4. Refill and Test

Sub-steps:
- Refill the engine with the correct type and amount of oil (consult the owner’s manual).
- Reconnect the battery.
- Start the engine and allow it to run for a few minutes while checking for leaks.
