Nice write-up.
How bad was your PCV valve? Did you look inside it to see if it was covered in crud or anything?

I was getting a P1283 code. Could also feel a loss of power around the 3000 RPM range.Good to know! stumble upon this randomly, wasn't searching for it or anything but def good info I can use in the future. Question though, what made you change your PCV valve?
I recently replaced mine too without removing the intake plenum.Thread resurrect, but just wanted to add that I was able to finally tackle my PCV replacement on 2006 4.0 Frontier. I have tried to get to it before, but never had the proper tool because it was in such a tough angle to get to. 170,000 miles with it never being changed, I figured it was time. I also replaced the hose because it was becoming brittle.
I was able to easily get the old one out and put a new one in with 23mm 1/2" socket, 3/8" flex head ratchet, 3/8" to 1/2" adapter. Didn't need to remove anything else, not even intake manifold cover.
Just sharing how I got mine off, in case anyone encounters the issue of removing it.
Sorry for the delay. No trick, the hardest part was getting the old hose and clamp off of the PCV. Just grab an adjustable set of pliers or needle nose, take the clamp off, pull the hose off. Then with the 3/8 flex head ratchet and 3/8 to 1/2 adapter and socket, start loosening it. This is the ratchet I usedThat is encouraging news. Can you please elaborate on it? was there any special trick you used?
Ditto here. Didn't have to remove the manifold cover - just used a 23mm 1/2" socket, 3/8" standard ratchet, and a 3/8" to 1/2" adapter. Probably took 5 minutes start to finish.
