PCV valve ?

[AVL Jeeper]

Hi! Just registered here, I guess this is where the action is now. I kind of miss the old board layout. Anyway,

I think I may need a new PCV valve. The plunger is loose in the housing. I can see it fall up and down if I flip the valve assembly up and down. I was under the impression that the spring in there is supposed to keep the valve closed untill the manifold vaccum opens it up. Is that true?

My truck is not idling very smoothly, so that is what led me to remove the PCV valve in the first place.

If I need a new valve, can I get one @ NAPA or Advance Auto? If not I will contact AB linn or Memphis Equip.

THanks for the help,
