EBPV Tube cleaning
Does anyone have a chemical that worked especially well for cleaning the EBPV tube? Mines is packed tight and I haven't been able to break it loose. I soaked it overnight in with brake kleen and it's still clogged.

Did you use a wire or something to clean it out? Simply soaking wont do much.

Is it the 90* end? It can be hard to get the wire through that turn. Soot shouldn't be packed so hard that a shot of brake clean wont break it up.

I banged that end on a vice and held the other end loosely and it made the tube vibrate when I banged it. After several taps rust started coming out as dust. I tried all the above methods with no luck but the banging opened it up. Good luck.

First time removing mione, i used brake fluid, let it sit up, then hit with an air gun, shot that crap all over the place.
Second attempt at removing it, i twisted the tube all to heck, now its removed, and has a bolt in where the tube/manifold meets. As for the sensor, got a 1/8npt cap, and capped it off, with it being ziptied off to the side.

I'm shopping for a new tube now. After letting it sock in carb cleaner I notice that I had tiny leaks in one of the bends. I never did get the tube cleared.

How bad can this get?
After I got my truck, a freind at the dealer sugested making sure it had flow, and was not rusted through. So one day, I pulled the sensor, took my small blowgun with wide rubber tip, and slowly applied air to the tube listening for any leaks, all I heard was the air rushing out the exhaust. So I gave it a few quick blasts of 140 psi shop air, used a small drill bit to clean out the sensor and called it a day. Should I have done more?
If I remember right, it is reading around 20 psi at 50-75% "throttle" do these numbers sound right?

I myself am kicking around the idea of this set up. Since at some point I am going to need to change out the hpop Driven Diesel HPOP Access Cover Kit

yea, I was listening for a leak near the front of the engine but did not hear anything obvious (indicates no sign of a leak at the tube, right?)
And as for the psi I am talking about when I had my snap-on verdict hooked up, I took a quick look at "exhaust back pressure" to atleast make sure it was moving, but at the time I did not know what an accurate reading was on these things. I don't even remember if the numbers I posted where right, but at the time I fiqured the lower the number the better (to a point considering turbo resistance and converter) and so long as the psi raised some with increased rpm ( sudden increased exhaust flow) meant that the sensor is atleast reading (even if not accurate).
if anyone knows what the correct readings for this should be I would appreciate it. When the Doc says I get my license back I will do another test drive cycle instead of relying on a memmory from 6+ months ago.
