posted in the excursion forum should have posted here. Thanks for any input. Hello every one I was wondering if I could get some different ideas. After changing out my tensioner on my 6.0 but not directly about 24 hours later I started getting a surge/power/smoking problem after accelerating. Seems to be no problem at idle. Last night driving from Nj to SC it seemed to do it after I stopped to pee. If I could get it back to 60-65 mph it would run fine but accelerating to there was rough. I change my ebp sensor and thought that solved it but it came back. Unfortunately I couldn't get the sensing line off so that wasn't cleaned. Unplugged the egr and thought that did it but it ended doing it again. When looking at the dashboss it looks like exhaust pressure goes up and boost goes to zero. It happens pretty rapidly. Does anyone have any idea what would cause the guide vanes to close is that a defuel or is that just the result of another sensor. It's a late 04 build with ipc on valve cover and ebp sensor at front of engine. Also it seems to happen at higher speeds. Going up and down hills at 75 or even 70 it seemed to do it often. I ran 60-65 between pee stops for hours without a hiccup

 

Any oil Out the back of the ICP sensor and Connection?

 

That was my next place to look more thoroughly but i didn't see any on my first look. I was just going to buy a new sensor but after paying full price for the EBP sensor i thought twice. Nothing is cheap on these engines. Just looking at tousley and even the pigtail kits are almost $60. Thanks for the suggestion. This forum is invaluable to owning one of these trucks if you dont want to be absolutely broke.

 

Do you think your concern is related to swapping out the tensioner? I know you can pinch the ckp harness with the tensioner by accident. Could your turbocharger be stuck? Or perhaps a fuel injector is failing?

 

checked wire bundle under tensioner and nothing pinched. I was also thinking that possibly the vanes were sticking closed and when power was needed they popped open then shut because of over boost and keeps doing that. im not sure how fast they actuate though if thats possible. it will cruise steady. I watched it go from 2lbs of boost up to about 12 and no problems but if i stop than take off it does it as power starts to build(start off like eggs under pedal) also i dont remember if at high speed it happens after coasting down hill and boost dropped way off or not because i wasnt thinking about that till later after a couple of stops.

 

Yea some Dealers are pricy but white bear Tousley has been pretty descent , I get most of my stuff from Clay over at Riffraff diesel.com , and they are supporters here on FTE. with a set of Gauges you can Monitor the Values of these sensors That's a OBD like scan gauge really effective , don't throw parts at it . that will get Very Expensive If you have Gauges what PID's do you need to Monitor ICP, ICPV , VGT,MAP, EBP also look for splits in the CAC boots this will slow the Boost to Turbo .

 

Have you cleaned the MAP connection to Intake the Little threaded nipple gets clogged while your in there get the IAT2 sensor , use Carb cleaner.

haven't done the map yet either. guess im going to be busy.

 

as you can see it looks like the vanes are going closed to not allow exhaust flow. I just dont know what other sensor to pull up but i did like at icp and i changes but not sure whats coming first or what is is causing the other things to react. but ill be busy cleaning stuff up. Also i read in a very old post about high oil causing missing because it foams. What is high oil in a 6.0. Mines at the max mark. They couldn't have designed an engine that would foam a half quart over?

 

Also wasn't trying to say tousley was expensive but these motors are no matter were you go. Expensive toys for big boys.

 

Plug in MAP EBP VGT and get the Sensors cleaned up you may have sticking Turbo Vanes lets see what the Gauge reads. are you high on the oil Dip stick? , most run a 5-40 synthetic 15 will be heavy, hope you mean this and not Making oil

 

not making oil i just put in 15 qts at change and puts it at max mark or just above

 

15 qts and you not dripping at the Bell Housing? Hmm I always did 13.5qts

 

nope but i guess that another thing i need to look at
