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.

I'm trying to update an old 51 pickup that hasn't run in years. What's the most affordable way to put a newer engine in it? I was thinking something like a small block, but I'm out of my depth.
The end goal is a dessert runner, mild offroad capability.
While driving my 2014 Silverado, I never have a problem if I accelerate quickly. However, there has been skipping/sputtering when I coast or slowly accelerate. This is not a clicking, loud knocking sound like I see most describe on here... Anyone have any idea what it could be? Thanks in advance! If needed I can try and video the sound later on today.
On Sunday March 8th I was driving my Sierra home from my parents-in law. I pulled out from a stop sign and was just getting up to speed when there was a loud bang followed by loss of power, Loud ticking noise, vibrations and a sulfur smell coming from the exhaust. I knew this was lifters instantly as it Happened to me in August of 2018, a short 11,000 miles ago. So, I took it in to my dealer who ran diagnostics and gave me the news That I would need lifters replaced yet again. Unfortunately, my power train warranty ran out December of 2019, so they told me I would owe a balance of $2900+ tax. Of course I was very upset with this news as I would have imagined the dealer would talk to GM and get this issue sorted out.. I mean it was only a few months over a year and less than 11,000 miles since they replacedall of the lifters and the cam shaft. I contacted GM myself and over the course of the last week have been working with the dealer and trying to talk to someone at GM who could help. Finally I reached a “senior analyst” who is apparently the top tier of customer assistance and she told me there was absolutely nothing they can do and I am responsible for the entire bill. I insisted that GM must know about the issues this engine has By now and should acknowledge and help their clients, but she offered no help.
How can I trust this engine again? I have read many posts people have put on this forum alone with this issue of failing lifters. How can anyone be expected to pay this much for an issue that is derived likely from GMs design of the afm system? Especially after we pay $50,000+ for the truck to begin with! I do not pretend to be an Mechanical or financial expert, but I feel I have been severely wronged in this situation. I have no choice but to eat this cost and sell the truck before the lifters have a chance to fail again.
I would suggest anyone doing research considering buying one of these trucks (I believe Sierra and Silverado 14-18 at least) that has the active fuel management system to rethink it. I would also go out on a limb and suggest my friends with 14-15 year Silverado and Sierras (with expired powertrain warranty’s) to consider selling them before the lifters fail on yours and you are stuck with a $3000-$5000 bill. Good luck all.
