Right side of the plenum, on the back, i forget what size wrench, but takes about 5 min. to replace, you do have a 3.5 correct? Pull off the hose,unscrew pcv, then install new pcv, connect hose then your done

I assume you know where it is. As you stand in front of the car it is just to the right of the throttle body at the back of the engine. You'll need to pull off the hose that is connected to it. Careful as it might split if it is brittle, forcing you to replace it.

I use this setup to get the valve out. It keeps me from having to remove anything else. I use a deepwell socket in the photo - I think std length may or may not reach the hex on the valve. I show two types of ratcheting hex bit wrenches - either will do

How do you know?

What are the signs that the PCV needs to be replaced?

There's not really signs it bad, but a worn out one will allow much more oil into the plenum than a normal PCV will. Let's say this, my car had 88K miles on it (3.2L), threw a rod and got a used motor. The newer motor plenum was in bad shape, mine was fine, OK swap plenum's. I stood my old one up on throttle body and the next day the amount of oil that drained out was a big surprised. PCV valve still had some 'rattle' to it, a new one was much louder rattle wise, hence less clogged. So every 2 years or so???

Late!

yea you can't really diag a PCV... basically remove it and shake it, if it sounds broken it's fine. If it sounds fine, it's broken lol.

Considering how simple it is to replace, and how cheap it is I make it part of regular maintenance. Once every 30k kms. It's a commonly over looked piece of maintenance tho, considering it's failure could mean total engine failure.

The 408 in my ram I went with the old school valve cover breather with a hose that feeds into the header. Now way hot oily air is being recirc'd into my engine.

Can you replace the PCV valve with an aftermarket one? or is it another part that you need to get from the dealer for proper fit and operation?Thanks.

In this instance, you DO want to go aftermarket for the PCV. OEM model seems to have some issues - there's a few threads here in the forums on the topic.

Wow

I drove one Intrepid 107K miles without ever changing the PCV, and one of my current ones has 168K miles on it without ever having changed the PCV. The other two both have 120K miles on them, again without changing the PCV. I'll take care of that when I get back from vacation.

I know, I know,...old thread...BUT, I think I am passing more than a little oil and came across this thread. I plan to change the PCV now as soon as I can get the time. I wanted to know a few things. First, if I have been passing oil, is all of that crap all the way to the exhaust tips going to cause me any issues? I mean there is really no way to clean it all out right? Second, other than the above pictured tools by SC.INTREPID, are there any other recommended ways to go about this to make it as easy as possible? And third, other than working on this while the engine is cold, to make it less likely I am gonna touch something hot, do I need to worry about any fluid spillage or anything or does this thing come right out and go right in, no problem? Thanks to all that can help me out here. J

Only other way would pull the wipers, cowl and brace. It's a tight fit.

Right out and right in. Be careful not to over tighten.

As others have said, better check your hoses too (cracks, clogging, embrittled, softened, etc.) - including the crankcase vent hose on the passenger side - it is part of the PCV system.
