Solution

1. Preparation

Gather Tools: OBD-II scanner, compression tester, leak-down tester, socket set, torque wrench, oil catch pan.
Safety Precautions: Ensure the vehicle is on a level surface, and engage the parking brake.

2. Address Oil Leaks

Locate Leaks: If leaks are found, clean the area and observe where oil is seeping from.
Replace Gaskets and Seals: Replace any worn or damaged gaskets, such as the valve cover gasket, oil pan gasket, or any seals identified.

3. Repair or Replace PCV System

Inspect PCV Valve: Remove the PCV valve and clean or replace it if it is stuck or clogged.
Check Hoses: Inspect the hoses leading to and from the PCV valve for cracks or blockages and replace as necessary.

4. Engine Reconditioning (if needed)

Compression Test Results: If compression is low, consider reconditioning the engine.
- Remove cylinder head if valve seals are faulty.
- Replace valve seals and/or piston rings depending on the condition.
Reassemble: Torque all components according to manufacturer specifications.

5. Oil Change

Drain Old Oil: Use an oil catch pan to drain the old oil completely.
Replace Oil Filter: Install a new oil filter according to specifications.
Add New Oil: Fill the engine with the recommended oil type and quantity.
