Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Addressing Oil Leaks

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Clean the engine area to identify the source of any leaks.
3. Tighten any loose components (e.g., oil pan bolts, valve cover bolts).
4. Replace any damaged seals or gaskets.

3. PCV System Inspection and Replacement

Sub-steps:
1. Locate the PCV valve on the engine.
2. Remove the PCV valve by twisting and pulling it out.
3. Inspect the valve for clogs; replace if necessary.
4. Reinstall the new or cleaned PCV valve securely.

4. Compression Test

Sub-steps:
1. Remove all spark plugs using a spark plug socket.
2. Insert the compression tester into each cylinder.
3. Crank the engine for a few seconds and record the pressure readings.
4. Compare readings against manufacturer specifications; replace or repair as needed.

5. Replace Spark Plugs (if necessary)

Sub-steps:
1. Clean the spark plug holes before removal to prevent debris from entering the engine.
2. Install new spark plugs with the correct gap setting (usually specified in the owner’s manual).
3. Torque the spark plugs to the manufacturer’s specifications (typically around 13 lb-ft).
