2002 LS1 PCV valve
Just doing some basic maintainance to my TA. Figured I would check the PCV valve. I see it's located to the left of the intake just behind the throttle body. It looks as though it has a rubber cover on it and has what appears to be a ground wire attached to this cover. I have never seen anything like this on any PCV system. How is the valve removed? I shook it and it seems pretty gummed up so I wouldn't mind spraying it down with some intake cleaner or replacing it.

I believe it just pulls out of the rubber boot. They are notorious for cracking where they attach to the intake and causing a vacuum leak.

I pulled a pic up of the replacement assembly I purchased from the dealership -- not cheap. There are threads on here of PCV mods and a repair utilizing a spark plug boot if you ever have other problems.

I was able to get it off no problem once I saw what I was dealing with. Has a crazy ground wire going to it that loops inside the rubber boot cover. I can see what you mean by cracking near the intake. I would hate to break that fitting off the intake because by the looks of it it's molded and part of it. That would suck!

I've also heard the strap is there to transfer heat from the engine block to the valve to keep it from icing up in the cold winter weather...but I'm not sure of its exact purpose(s)
BTW OP, if your PCV boot does crack/fail, may I suggest a PCV upgrade? Might be time to consider an LS6 valley cover and oil catch canLast edited by Cutlass; 09-05-2010 at 06:39 PM.
