Solution

1. Preparation

Gather tools and materials. Ensure the vehicle is parked on a level surface and the engine is cool.
Tools Required:
- OBD-II scanner
- Torque wrench
- Socket set
- Oil catch pan
- Engine oil (manufacturer recommended)

2. Address External Leaks

Inspect and replace any faulty gaskets or seals identified during the visual inspection.
- Sub-steps:
  - Remove components obstructing access to the leaking area (if necessary).
  - Clean the contact surfaces thoroughly.
  - Apply gasket maker (if applicable) and install new gaskets/seals.
  - Torque to manufacturer specifications.

3. Replace PCV Valve

If the PCV system is clogged or malfunctioning, replace the PCV valve.
- Sub-steps:
  - Locate the PCV valve (usually on the valve cover).
  - Disconnect the hose connected to the valve.
  - Remove the old PCV valve and install the new one.
  - Reconnect the hose ensuring a tight fit.

4. Engine Oil Change

If oil contamination is suspected, drain and replace the engine oil and filter.
- Sub-steps:
  - Place an oil catch pan under the oil pan and remove the drain plug.
  - Allow the old oil to completely drain.
  - Replace the oil filter using an oil filter wrench.
  - Reinstall the drain plug and torque to manufacturer specifications.
  - Fill the engine with new oil through the oil filler cap.

5. Monitor Oil Consumption

After repairs, monitor the oil level over the next few hundred miles.
- Sub-steps:
  - Check the oil level weekly for the first month.
  - Keep a record of oil levels to identify any patterns or changes.
