Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, oil catch pan, and rags.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical issues.

2. Address Oil Leaks

Inspect and Replace Gaskets:
- Remove engine covers if necessary to access valve cover gaskets.
- Replace valve cover gaskets if they are leaking.
- Inspect and replace the oil pan gasket if oil is leaking from the pan.
- Torque the new gaskets to manufacturer specifications.

3. Repair or Replace PCV System

Inspect PCV Valve:
- Remove the PCV valve from the valve cover.
- Check for blockages by shaking the valve; it should rattle.
- Replace the PCV valve if it is clogged or not functioning properly.

4. Engine Rebuild (if necessary)

Compression Repair:
- If compression test results indicate cylinder wear, consider a rebuild.
- Remove the cylinder head and inspect piston rings for wear.
- Replace piston rings if necessary and reassemble the engine, ensuring all bolts are torqued to specifications.
