When you shake the valve does it rattle?

Jsun3701 · Dec 4, 2006

It fits really loosely I havent taken it out yet. Does it just pull straight out?

No it doesn't, at least it did not on my 02'. I had to pull the cam cover off to take it out. It had a metal clip that holds it to the cover from the inside. I put a plastic plug in it's place, a breather filter on the fill cap and another filter on the driver side cam cover. ... I don't have the oil fill cap breather in place in the photo but I have the one on the drivers side cam cover installed (next to the clutch cable and brake reservoir).

do NOT get an autozone PCV... they're terrible and allow a ton of blowby

Kilgore Trout · Dec 4, 2006

Do NOT install breathers or modify the PCV system airflow in any way.. It is ok to filter it but do not block it or modify the flow.

Why? I don't understand what you mean, you said do not install breathers but it's ok to filter it? Please set me straight... As for EPA standards.... I don't care

Kilgore Trout · Dec 4, 2006

Do the research, there is a ton of information on this on the internet. And no it does not have to do with EPA.

There is nothing wrong with using breathers, but you have to do it correctly. You have to use them on both sides, not just one, or it will allow unmetered air into the system.

That is indeed one of the many schools of thought on the issue... I do not agree however.

Thanks again for the knowledge you have added to this thread.

I don't mind if you dissagree but atleast back it up with something useful.

if the car has funky idle, it MAY be the PCV, but have you replaced the IAC yet? If not, try cleaning the IAC and see if the problem goes away. If it does, you know it's the problem, and you can buy a new one (because cleaning it is only a temporary fix).

I doubt his idle has anything to do with the PCV other than it may have gummed up the IAC.

Things to check first for wandering idle:
IAC, TPS voltage, vacuum leaks.

Jstreet...do you have a link that shows all the vac locations in our cars? That would be helpful for me too....

this is the only one I have. It if for a 98, so I haven't found it very useful. They are pretty easy to find to the old. 5.0's

Ram5773 · Dec 4, 2006

Has any one else encountered having to remove the valve cover to remove the PCV on a 02 like RoxStang did? Did I misunderstand on how to replace it, I thought the PCV was unscrewed or pulled out
