2.3L ('83-'97) Reman. Cylinder Head Saga

If you have to ask if you should replace your PCV valve, you need to replace your PCV valve. They cost like 3 bucks, come on!

I didn't realize they were that cheap! It sounded like a $50 part, I always though it was a more fancy than just a piece of plastic. $1.85 with tax...

Some are a bit fancy with heater lines running around it, but for the most part they are cheap and simple. Just a tube with a weight and spring inside but a pretty critical little part.
