Guys, I am not sure what you are talking about. There is no PCV on a 2.5 engine. None. On the front of the valve cover (driver's side) is a small brass fitting with a narrow hole. This orifice acts as the PCV valve. It plugs into the vacuum system leading to the intake manifold. It is in the second photo by Andywear. All of the filters and PCV valves in the other photos were "add ons" by previous owners (or current owners.) This orifice works the same way the PCV valve works on other vehicles. It is narrow because that is all that is needed to this particular job. Good luck with it. Take care.
