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.
Wondering if anyone has done a pcv delete and run a breather style setup on an l83/l86 engine? Seen it done on older ls stuff and guys talk about a much smoother idle. Recently had a cam swap done and looking to keep intake and valves clean lol.
