Just an update, turbo was toast. Got the new one on and all is well. New turbo has a different personality than the last but it's making boost and seems to be good to go.

That is true. I always use the wrong terminology for those. That does make sense that perhaps the collar isn't having as much travel as the old thus not using the exhaust as efficiently to drive it. I just wasn't sure of in the build process something gets set as far as tightness and perhaps...

Howdy, I see a lot of AC issues but in searching for my symptoms, I didn't find a thread so I am looking for info. My 2008 6.7 Megacab is only blowing hot air from the vents. The compressor is running all the time if the AC switch is turned on, never cycles the clutch off at all. I am hoping...

Howdy gang, I have some questions about my turbo on my 2008 6.7 cummins. A few weeks back I had my turbo replaced on my after market warranty. The replacement turbo was very noisy in terms of spooling, at about 2lbs you could really here it spool up which I actually loved to hear. Unfortunately...

Howdy, I towed it to the shop after trying and testing the things I could. They threw a scanner on it and it was making boost at high engine speed but when it was above idle to fairly high rpm, it didn't do a thing...vanes are apparently hung up. They will get with the mfg and get me a new turbo...

Myself and a buddy of mine are kinda leaning towards this, he is sharper than I am on the failing turbo issues and he fells pretty strongly the vanes have stuck in a position where its dumping to the exhaust basically, my exhaust noise is much MUCH louder since this issue happened so I am...

It could be, Im not sure if it would be sooty enough with only being a few weeks old but it may be a bad turbo. Hopefully I can learn a little more about it tomorrow with a scan tool that can cycle the vanes and also perform some position readings.

I really think it is the turbo...something along the lines of the vanes being hung up. I am hoping a friend of mine can come thru with a scan tool that is capable of reading the vane positions and cycling them. That would help me pin it down better and give the mechanic a decent starting point...

Yesterday I posted the following under the normal 6.7 drivetrain forum and didn't get any ideas, truck is still down and everything I have come up with has not been the issue it appears. Today on the way home after about 130 miles of driving and thankfully only about 2 miles from home, my...

Today on the way home after about 130 miles of driving and thankfully only about 2 miles from home, my truck lost its mind. I had just topped a hill and it pulled fine, nothing out of normal and as I coasted to a stop sign, I noticed all the sudden it was making much more exhaust noise, surging...

Howdy, anyone still around for our central area lol? I was just checking it out and saw it hasn't had any postings since 2011. Just hoping to find some other local/semi local folks to hang with.

I appreciate the info, I haven't had this truck very long so I am trying to get ahead of maintenance items since they are unknowns and trying to get my learning on to make sure me and the truck have a long happy life together. Im now chasing an odd whine it has. I have an aftermarket warranty on...

I read on here the other day where someone had mentioned they try to keep the exhaust gas temps at 600 degrees or below when towing and today I spent a little more time eyeballing my Edge CTS and I am all over the place temp wise....I was just driving to work and at one point I saw 646 degrees...

OK, that makes me feel better about it lol. I appreciate the info! It is seamless to me other than my CTS will beep and throw up the R and then I see the exhaust temps raising, otherwise I wouldn't have any idea it is going on.

Howdy gang, I did some searching on the forums and didn't see exactly what I am looking for so I wanted to throw this out there and get some feedback. I have an 08 MegaCab and on the weekends I have been doing runs down to the lake to do some work, its a 2.5 hr drive each way and I avg about 70...
