I wish people wouldn't post information without doing their research first.

Your PCV is not dirty. Thats a special type of PCV valve. It's meant to reduce oil consumption.

That's my point so they shouldn't sell a replacement just a cleaning should be suffice IMO

and if you haven't done this I strongly recommend it. I know my truck drives better after replacing it. $4 at Napa and 30 seconds of your time.

What kind of issues do you encounter when the PCV valve is bad? I like to do little fixes like this but I don't know if mine needs to be replaced

Fixed orafice as in it is not supposed to come out???

Increased oil usage for one. Mine is the rattle type. Seems to vary from year to year. Truck just seems run better like I freed something up or it's breathing better.

LOL the old ones rattled the new ones do not. there was a service bulletin about this somewhere

So this is what I am dealing with, it really does look like its not meant to come out, I looked at the PCV valve I was given at the parts store and there is no way that it could fit back where this one belongs, so Im thinking that some of the blocks do have a removable PCV and others don't.

It pulls out. The PCV has to be removable, it gets clogged up and is a part meant to be replaced. I thought the same thing when I saw my PCV.

I have an 04 4.8L, and mine looks exactly the same. I cannot figure out how to get it out either. I read somewhere else that the 2004's and up have a permanent PCV. That doesn't make any sense to me, but looking at it in my engine bay, I can't for the love of christ figure out how to get it out either. I've also noticed that when you are searching for a PCV on parts websites, some will show one available for my yukon and other places will not (autozone shows one available, summit racing does not).

Update: I went ahead and checked a couple of other online retailers for the PCV for an 04, 4.8L:

Napa - N/A
O'Reilly - N/A
Advanced Auto - listed one as available, same thing as autozone, here's what they are recomending:

If THAT is what the PCV looks like for my yukon, I don't see ANY way of getting the old one off and the new one on. I will try to post some close ups after work.

I also read elsewhere that on 04's and up the PCV is permanent, mine definitely needs to be cleaned, just have to figure out how to do it...
