Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, oil catch pan, shop rags.
Park the vehicle on a level surface and allow the engine to cool.
Disconnect the battery to ensure safety while working.

2. Locate the Leak Source

Sub-steps:
1. Clean the engine area with a degreaser to remove existing oil for better visibility.
2. Start the engine and let it idle while observing for leaks.
3. Identify the exact source of the leak (e.g., oil filter, drain plug, valve cover).

3. Replace Faulty Components

Sub-steps:
1. If the oil filter is leaking, remove the old filter using an oil filter wrench.
2. Clean the mounting surface on the engine.
3. Install a new oil filter and tighten it to the manufacturer's specifications (typically hand-tight plus 3/4 turn).
4. If the valve cover gasket is leaking, remove the valve cover by loosening bolts using a socket set.
5. Replace the old gasket with a new one, ensuring proper alignment.
6. Reinstall the valve cover and torque bolts to the specified value (usually around 8-10 ft-lbs).

4. Refill Oil and Check for Leaks

Sub-steps:
1. Drain any old oil if necessary using an oil catch pan.
2. Refill with the correct type and amount of oil as specified in the owner’s manual.
3. Start the engine and allow it to run for a few minutes, then inspect for leaks again.
