Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to avoid electrical issues.

2. Address Visible Leaks

Tools Required: Socket set, torque wrench, gasket scraper.
Sub-steps:
- Inspect and tighten any loose bolts on the valve cover.
- Replace any damaged gaskets or seals identified during inspection.
- Clean the area around the leaks and observe for additional oil seepage post-repair.

3. Replace the PCV System

Tools Required: Pliers, socket set.
Sub-steps:
- Locate the PCV valve on the valve cover.
- Disconnect the vacuum hose connected to the PCV valve.
- Remove the old PCV valve and replace it with a new one.
- Reattach the vacuum hose ensuring a snug fit.

4. Perform an Engine Flush (if applicable)

Tools Required: Engine flush additive, oil change equipment.
Sub-steps:
- Add engine flush additive to the oil and run the engine for the recommended time.
- Change the oil and filter afterward, using the manufacturer-recommended oil type.

5. Compression Test (if excessive consumption persists)

Tools Required: Compression tester.
Sub-steps:
- Remove spark plugs from each cylinder.
- Insert the compression tester into the spark plug hole and crank the engine.
- Record the compression readings to determine if any cylinders are significantly lower than others.
