3. Replace any damaged gaskets or seals as necessary (e.g., valve cover gasket).
4. Refill oil to the proper level if it was low.

3. Check and Replace PCV Valve

Tools Required:
- Pliers
- New PCV valve (if necessary)
Sub-steps:
1. Locate the PCV valve, typically on the valve cover.
2. Remove the old PCV valve using pliers.
3. Install the new PCV valve, ensuring it fits snugly.
