Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal.

2. Inspect and Replace Gaskets

Sub-steps:
1. Identify the source of any external oil leaks.
2. Remove any components obstructing access to the leaky gaskets.
3. Clean the mounting surfaces thoroughly.
4. Replace the gaskets with OEM parts; use a torque wrench to tighten according to the manufacturer's specifications.

3. PCV System Inspection and Repair

Sub-steps:
1. Locate the PCV valve and hoses.
2. Remove the PCV valve and inspect for clogging or damage.
3. Clean or replace the PCV valve if necessary.
4. Check and replace any damaged hoses.

4. Compression Test

Sub-steps:
1. Remove all spark plugs for easier access.
2. Connect the compression gauge to the first cylinder.
3. Crank the engine and record the pressure reading.
4. Repeat for all cylinders and compare readings. Replace worn piston rings if necessary.

5. Turbocharger Inspection (if applicable)

Sub-steps:
1. Inspect the turbocharger for oil leaks.
2. Check the oil feed and return lines for blockages or leaks.
3. Replace the turbocharger if it is found to be faulty.
