My car is creeping up on 100k quickly and I wanting to replaced the PCV valve since it hasn't probably ever been changed but I don't know where it is at. So I'm needing a good break down of where it is and how hard it will to be replace and maybe a link to where I can buy the PCV valve itself. My car is a 2010 Focus SE with the 2.0 Duratec engine. It anyone needs more info just let me know. Thanks.
