Excuse me for a newbie question... I bought a 2002 Ford Focus ZTW with Zetec a month and a half ago. Today when I opened the air filter housing (to do MAF sensor cleaning) and noticed there wasn't anything where the Chilton book says a PCV filter goes. (a little plastic piece seems to have come off from there, also..?) Shouldn't a PCV filter be placed there to keep dirt from entering the hose? If I need to get one, can anybody tell me what the OEM part is and where would be a good place to get one from? I appreciate your help in advance!
