Unplugging the EGR
But the CAT is the one in the DP right??? I initially thought the CAT was right in front of the DPF but was told that is the NOx filter. Now THAT has flanges on both ends and it looks just like a CAT. Now I'm getting confused again and I have that deer in the headlights look.

Yep 2 flanges. You got life good. But let me burn up mine for a bit first.
I'll be blowing past you in December, but probably at the wee hours. I want to get out of your fair city in a reasonable amount of time this trip. This is another 3000 mile test run with the PMT for Bud too.
Well, all I can say is that there are a lot of mis-informed people around pertaining to what is what in our emissions system. I'm gonna try to find a diagram that shows everybody what is what....
Off to try and install a freezeplug in my EGR tube....

I just did that last night on that other truck. It's a Dorman 555-020 plug. . .I think. . . Memory is failing. . .
I bought a simple 1 1/8" freeze plug from NAPA. Installed in on the left side as you look at it. It was a tight fit but a few taps with a hammer and it went right in the tube and it all buttoned back together nice and easy.
I also decided to dump the PCV hose while I had the hood open. I unhooked the hose from the metal tube coming out of the head. I ran a hose to that metal tube and just ran it down so it will drip on the ground for now. I left the hose attached to the intake hose but couldn't find anything large enough to plug the tube. I ended up using one of my spare 1/2" drive socket extensions. The smaller side went in the hose easily and then I had to force the wider end into the hose. Once I got that in far enough I put a bigger hoseclamp on it. I doubt I'll notice any kind of difference from this but it makes me feel better that I have now done it...
Oh, and yes.

Thanks for all your testing so that I didn't have to do it.

Dodgezilla, you can get a 1/2" male pvc pipe plug and it will fit in the intake side real nice.
Back to running clean and mean!


Coincidentally I was at work today doing much the same thing. Except I didn't go to the trouble of getting a freeze plug. Just cut a circle out of sheet metal and formed it to fit at the passenger side of the round tube. Opened up the egr valve where I blocked it before and did find a bit of crusty soot mixed with condensation, but it was not goo at all. Maybe it is because I drive it like I stole it who knows. But decided to do a little blocker in the tube to prevent any more anyway. It has been 10k miles since I did the block to begin with so it wasn't too bad.

Maybe your climate is dryer than ours. Mine ran up and down the east coast and in allot of Rain. Dodgezilla will tell you about rain in Baltimore. The humidity is horendous here. If that's the case, these things have to be designed to meet everyone's conditions.
I hate engineers. . . Too bad I am one. I'm a better mechanic though
Been running for a few days without the EGR. I noticed today while the truck was idling that it rattled pretty loud there for about 30 seconds. Once I got back on the road, it was fine. Even the next time I was sitting at idle it was fine. Anyone else experience this at all? Mileage is still way up.

Actually that's the engine purring because you made it feel goooood

Yes the check engine light will come on.

Oh and Polaraco, Yes i do live where it is dry. Usually around 8 % humidity. Still had some condensation roll out when I opened it up, but not too much on the soot side. May be because it is an 07 and has the AV flash. Might not be making as much soot as some others.
Sounds like your intake butterfly may have tried closing on you. The engine does rattle a bit more once you unplug the EGR but it's not like a really bad timing rattle or anything. Now, when it is cold out you will get some timing rattle because unplugging that EGR will bump your timing up some. Once the truck warms up it goes away though.
After 2500 miles my tube didn't have any slime pouring out of it or anything like that. It was just soot in there but it was wet from moisture and quite nasty.

Well believe me, compared to the 99 I had, the rattle is quiet. However, it has happened a couple times. For now, the truck is running great and I don't plan on plugging it back in for now.
