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. JeffD
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.
Sorry to revive an old thread, but is it advisable to take this cover off to clean the PCV? What is behind it?
