PCV Valve Location - Help Required

Currently working on a 6.0L V8 (2000 LQ9 I believe) and cannot seem to locate the PCV valve and hose (see image for reference).

 

 I was under the impression that they weren’t integrated into the valve cover until around 2005. The body of this truck is a 2000 Sierra 1500 but the engine was replaced from the 4.8 to the 6.0 at some point so I’m guessing for a lot of the component locations.

 

First time poster, any helps appreciated.

It’s right underneath the plate that holds the cable to the throttle body. You can see it in the picture it’s halfway underneath in the front on the intake manifold. It has a small 2” long hose attached to it, follow the plastic tube that’s attached to it. It goes to the left side valve cover where the Pcv is.

Thanks for your help man, I've attached an edited photo of the engine bay. Is that the particular hose you were talking about? I've watched nearly every video online, and I don't seem to have the matching "thicker hose" that enters the drivers side valve cover.

It’s above the one you highlighted 

Oh I see, the cable directly up from the one highlighted in the rectangle? Has a black 90-degree fixing just under the plate you described?

Yes, that’s the one. You follow it to the valve cover and the pcv should be there. I have 2001 Silverado, it’s the same thing.

You're a legend. Thanks again, will finish that off tomorrow!

What is the plastic bit called that comes out of the top of the engine ???? it broke off of the actual hose that connects to the pcv i dont know what that part is called i have the valve but i cant replace it because the thing under the plate that has 3 bolts broke

      Needing this part.

      Still looks like a rivet to me in the pics, I don't see a nut and none of the pics show the head of the screw. But if you says so.....

      Tire psi

      By jgaudet99 · Posted

      Thanks for all the help so far!   I did try right from 2026 right down to 2021, and only from 2023 down lets me select the option for tire psi change, but I get the vehicle not supported error!   I'll definitely try it under Chevrolet after work today, and I'll get the sensor number from gm for my truck tire sensors. And I'll let you know if it works for me under Chevrolet!   And if that doesn't work, I'm going to guess that what @Atlas said about maybe I have a different body control module could be true!

      2010 Avalanche 5.3 not running correctly after engine swap.

      From where I'm sitting this sounds like a compatibility problem. I'm assuming the 2007 was a 900-series truck, and not an 800-series (they were sold side-by-side in dealerships that model year), since it starts and runs.   This is why I HATE post-2006 vehicles. Everything becomes a huge problem when you try to keep the thing running for longer than the manufacturer has designed it to.    I can't remember when Global-A architecture started - either '10 or '11. For your sake, you had better hope it's '11, or you're going to be spending some BIG money to correct this cluster-eff. That's something you need to find out before doing anything else. You may have several computers bricked ... but the fact that it runs tells me you MIGHT be ok here.     EDIT: Just did a quick refresher. You're screwed. This is Global-A. The 2 systems are NOT compatible in the slightest. Once you get the correct engine in there that IS compatible, you're going to need to see how many computers are locked. Absolute NIGHTMARE to straighten out, too. Your buddy might be better off cutting his losses and finding something else.   Welcome to post-2006 vehicle electronics. This is why I quit the industry, and drive nothing built after 1994. This stuff takes all the fun out of wrenching!

      Tire psi

      True, hard to say what differences there may or may not be between Chev and GM as well as a production year or mid year part change either.    I just found it odd that under the Sierra choice on the Autel that many of the last few years of production year did not include the choice of changing the tire pressure but if that is an Autel thing or a GM thing as to why the choices were not there. Knowing what tpms sensors are on the truck should give some guidance into which choices on the tool even make sense to try as I wouldn't give up just yet with the tool but I guess he will see what if anything he comes up with if he finds out a bit more info and tries a few more things on the Autel.
