Access to the PVC hose behind intake..
(DUH... I mean PCV... )
How do you guys check this?? I see where it winds it's way to back, but it's lost after that.. I can't even get my hand back there to feel around..
I had a single P0171 code pop up on me on Friday... Of course I searched and found the most likely cause was a vac leak.. This usually would also produce the P0172 code as well from my readings, but I did only have the single code..
Anyway, I checked the PVC in the valve cover and it was fine as it clicked away as you shake it... The rubber elbow was nice and tight too. It has a metal tube to go on it's way to the back of the intake and that's where I can't get to it.... I suspect that there is another rubber elblow connecting it to the intake?
I have since determined that it's not the problem (PCV hose vac leak).. It seems to have been my fuel filter... I cleared the code with my code reader and have only put on 30 miles of mixed driving and no CEL yet..
I know it's still not gone thru it's full drive cycle yet, as the code reader tells me it's not ready for Emissions test yet..
So, back to the actual question! How in the heck do you get back there!

I understand yuh Mitch, -The Positive Ventshaft Crankelation (PVC) assembly - Ours connects directly behind the plenum base Mitch, or throttle body elbow. Yea, you can feel it up or move it around by hand while she's running. If it's getting thin back there, it will break off, then you'll hear it real good lol.
You can use a pry-bar type screw driver to work it off the stem. It connects right here -
Hose looks like this -
They go bad right here -

Thanks Jbrew! I guess I was thinking of "Pollution Control Valve" for that thing... 
So, either term works I guess!
I just hope I don't have to get to that thing anytime soon!
Thanks again.

Yea, you CAN slide it off after removing just your air intake. Squirt a little WD40 at the end of a long screw driver, then nudge it off. Then the entire system can be removed without taking anything else apart.Sometimes they do cook to the connection tho. If it don't want to budge, that's a sign that it's getting bad or will be , -by the time you finally get it off there lol.
