Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface.
Disconnect the battery to prevent any electrical issues.

2. Replace PCV Valve

Remove the old PCV valve:
- Locate the PCV valve on the engine.
- Disconnect the hoses attached to the PCV valve.
- Twist and pull the valve out of its socket.
Install the new PCV valve:
- Insert the new valve into the socket until it clicks in place.
- Reattach the hoses securely.

3. Address Oil Leaks

Identify and repair leaks:
- Use a degreaser to clean the engine area before inspection.
- Replace any damaged gaskets or seals found during the visual inspection.
- Tighten any loose bolts or fittings that may be leaking oil.

4. Perform Engine Rebuild (if necessary)

If compression tests indicate severe wear:
- Remove the engine from the vehicle.
- Disassemble the engine, inspecting all components for wear.
- Replace piston rings, gaskets, and any worn parts as necessary.
- Reassemble and reinstall the engine, ensuring all bolts are torqued to specification.
