Where is PCV valve on 2000 Focus DOHC ?

Auto parts dealer sold me one with airfilter but I don't see it on the car. Where is it?

Thanks.

your pcv is actually a hose that runs from you valve cover crank case to the intake box. I think the filter you are talking about (looks like an air filter about the size of a golf ball or so) replaces the hose. you take off the hose and put the filter on the valve cover where the hose used to connect to. but honestly it does note improve performance and from what i have heard is not good for the engine. plus you wont pass smog

I know that the PCV on the Zetec in the Escort is behind the exhaust manifold; supposidly a bitch to take off, and I'd imagine that it'd be in the same place on the Focus' motor. Try a Haynes book from your library for instructions.
