Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is on a level surface and the engine is cool.
Disconnect the negative terminal of the battery for safety.

2. Inspect and Repair External Leaks

Sub-steps:
1. Use a wrench to remove any covers obstructing access to the oil pan and gaskets.
2. Clean the area around the oil pan and inspect for cracks or damaged gaskets.
3. Replace any leaking gaskets or seals with new ones.
4. Reinstall any covers and reconnect the battery.

3. Address Internal Oil Consumption Issues

Sub-steps:
1. If compression or leak-down tests indicate issues, disassemble the engine as needed to access piston rings or valve seals.
2. Replace worn piston rings and valve seals using a ring compressor and proper torque specifications when reassembling.
3. Ensure all surfaces are clean and use appropriate lubricants on new seals and rings during installation.

4. PCV System Repair

Sub-steps:
1. Locate the PCV valve and remove it from the engine.
2. Inspect the valve for blockages; clean or replace as necessary.
3. Check hoses for cracks or blockages and replace as needed.
4. Reinstall the PCV valve and hoses securely.
