    When I did the PCV valve on my wife's car it looked like nothing more than a metal housing with a ball bearing rattling around inside. That left me wondering, why not just clean and reinstall the original valve? Is there a reason why that wouldn't be nearly as good? I realize it's a $10 part but I have to ask the question before I go buy another for my own car.

    The Gen2 Prius PCV is a pain to get at. If I were going to make that effort, I would use a new PCV.

    I recall paying ~$6 when I bought the PCV valve a few years ago for my 2004.

    You could immerse the valve in gasoline or similar solvent to clean it, but why bother.
