To be certain, you should:
* Consult a repair manual: A Haynes or Chilton manual specific to your year and model Celebrity will have a diagram showing the PCV valve's precise location.
* Use an online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, etc.) allow you to select your vehicle's year, make, and model to view a parts diagram. This will show you where the PCV valve is located on the engine.
Looking for a small, usually black, plastic valve with a hose connected to it is a good visual indicator once you're in the general area. Be careful not to confuse it with other vacuum lines or emissions components.
