Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Gather tools including an OBD-II scanner, socket set, torque wrench, and oil catch pan.

2. Address Oil Leaks

Sub-steps:
1. Remove the engine cover (if applicable) using the socket set.
2. Clean the valve cover and oil pan surfaces with a suitable cleaner to remove old oil and debris.
3. Inspect gaskets for wear; replace any damaged gaskets (e.g., valve cover gasket, oil pan gasket).
4. Reinstall the valve cover and oil pan, ensuring to torque bolts to manufacturer's specifications.

3. Replace PCV Valve

Sub-steps:
1. Locate the PCV valve, typically found on the valve cover or in the intake manifold.
2. Disconnect any hoses attached to the PCV valve.
3. Remove the old PCV valve and replace it with a new one.
4. Reattach the hoses securely to the new PCV valve.

4. Perform Engine Oil Change

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Place an oil catch pan under the oil pan and remove the drain plug using a socket wrench.
3. Allow the old oil to drain completely, then replace the drain plug and torque to specification.
4. Replace the oil filter using an oil filter wrench.
5. Add the recommended type and amount of new engine oil (consult owner's manual for specifications).
