Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Address Oil Leaks

Tools Required: Socket set, torque wrench, gasket scraper, oil catch pan.
Sub-steps:
1. Identify the source of any oil leaks found during diagnostics.
2. Remove the affected component (e.g., valve cover, oil pan) as necessary.
3. Clean the mating surfaces thoroughly using a gasket scraper.
4. Replace gaskets or seals that are worn or damaged.
5. Reinstall the component, ensuring to torque bolts to the manufacturer’s specifications.

3. Replace PCV Valve (if faulty)

Tools Required: Pliers, socket set.
Sub-steps:
1. Locate the PCV valve, usually found on the valve cover.
2. Disconnect the PCV hose from the valve.
3. Remove the old PCV valve and replace it with a new one.
4. Reattach the PCV hose securely.

4. Address Engine Wear

Tools Required: Compression tester, possibly new piston rings (if needed).
Sub-steps:
1. If compression test results are low, consider an engine rebuild or ring replacement.
2. Remove the cylinder head and inspect for wear; replace piston rings if necessary.
3. Ensure all components are cleaned and reassembled correctly.
