Ford 6.0L Power Stroke Diesel :: 2004 - Turbo Not Boosting Properly
Jun 28, 2015
I have an '04 6.0 and it doesn something strange. When for example I am going up a decent grade hill and passing, if I have to let off the throttle and then re apply, the turbo won't build boost, it sits at a couple pounds for a few seconds. Then after a few seconds it will build boost quickly again and work generally as normal. If it doesn't respond and I really need to get it to build boost NOW, if I push the accelerator to the floor, the delay shortens and it will often kick down a gear and then build boost. So if I gently accelerate, very slow to recover, if I hammer it, much quicker but regardless, when it's happening it's almost always the same situation, fully warmed up truck, warm/cold/freezing day and it happens when I back off and re apply. Thinking maybe a worn unison ring but not sure..

My 2012 f250 is been acting weird, usually the truck is boosting while on gear when I'm at a stop (around 0.40) I think that's normal on a 6.7 because it's always done it, but since yesterday I noticed it sounds different and it's not on boost anymore it just vacuums while on gear at a stop (around -0.25) I'm thinking it's the wastegate solenoid but I'm not 100% sure, and the truck doesn't boost as fast as before but it drives fine and I'm actually getting better gas mileage since it doesn't boost as before, what it could be? It's tuned and deleted....

Are they known to cause any noise? VGT Solenoid.
I have recently developed a slight whistle/squeal when boosting and when letting off on the pedal. I initially thought I had a CAC boot starting to split out, but since it's making the noise when I let off as well I doubt that the problem.
It isn't constant, and only does it for a second or two when it happens. It's not extremely loud, just loud enough to make you wonder what the heck it is...

I have a 2004 Excursion with the 6.0. Lately it seems like the motor just doesn't have the boost it should. Funny thing is that the boost reading through the edge cts seems to be right. Under full acceleration it will pull 27 psi boost and 3900+ ICP pressure. No codes are being thrown. It just doesn't "feel" right (seat of the pants) and it also sounds louder but I don't known this for sure.
Where does the CTS get its boost reading from? The truck has new boots on the hot side from riffraff. Anything I can check?

Ok so I just replaced the oil cooler, added 2 coolant filters, changed the oil/filter, and both fuel filters, and installed the updated turbo drain tube. I get it all back together, it takes a minute before it will fire but I figured that was normal for not having any oil in the sump under the cooler and changing both fuel filters. Everything seems fine, checking for leaks and I notice that I don't hear the whistle of the turbo so I go look at my edge CT and have zero boost and it stays at zero even if I rev it a bit. Obviously I didn't redline it or run it for very long maybe a total of 10 minutes over several times.
I will note that I did find a plug for the driver side injectors wasn't plugged in the first time I started it, but I shut it down pretty quick and plugged it in. So then after I noticed the turbo not spooling I used the chip to pull the codes and had a whole bunch related to the unplugged harness and one for turbo underboost. Figured it was because the harness was unplugged so I just cleared the codes and tried again, now I'm not getting any codes but I'm also not getting any turbo boost the only code that it is throwing is the P1000 "on-board diagnostic systems readiness test not complete" do I need to go drive it for the learning sequence because I had the batteries disconnected for a couple days?

The 2004 and 2005 turbo is interchangeable and can you replace the bearing in it.

It started after a blue spring upgrade. my turbo would not spool until we revved the engine hard then it kicked in and it's kinda worked since then.. it feels like the truck is struggling on acceleration and the boost builds fast up to 30lbs, the EBP seems to be stuck at 21.48psi until your in 3rd then it jumps and I have power again, also the turbo dumps (farts) if I let off even a little until the EBP jumps then no issues. I replaced the sensor and it's stuck at 21.48 all the time.
Now, I unplug it and it jumps between 26 and 28psi, plug in the old sensor while it's out laying on the motor (not installed) and right back to 21.48. I don't know where to go with this and it's my only truck so I need it running. also it was blowing the intercooler boot off at the turbo during a normal acceleration and the turbo spool has a howl to it when EBP is stuck...

My friend is working on a 2004 6.0 F-250 and it has used 75% of the coolant in the overflow bottle in 5 days. Can't smell coolant either. The inside of the tailpipe is wet soot black and there are wet spots on the tube coming from the intercooler to the turbo at the turbo and the intercooler. He's thinking EGR cooler.

Ok so I just put an egr delete and a new oil cooler in the truck. Everything went pretty well but when I was going for a test drive I'm not building any boost. I can here the turbo whistle like always but there no power and none of my gauges register boost. Also, the transmission is shifting funny I don't know how else to explain it but just not right. Now I don't see/smell any exhaust leaks and can't hear anything too wierd in that department. I checked the intake and the intercooler tubes I think their called and all good there. However, I did break my map sensor post off my intake during the install . So my map tube was just open to the atmosphere I didn't plug it or anything. Could that be the cause of my woes? Is there any thing I can do to alleviate the issues I'm having with the map? Can I just plug it until I fix it? And is there anything else to check on my turbo?

Weird thing happened today. Was out running errands, and upon pulling out into traffic I felt the truck lag a little. I figured it was the typical trans hiccup we all experience from time to time. As I continue driving, I notice I don't have any turbo boost.
I'm cruising around 55-60 and when I slowly give it gas......No boost. I stomp it and the turbo gauge slowly climbs to about 12 psi. At this point I waiting for the truck to throw a warning message and none came.
As I'm reaching my destination, the speed limit is 30 so I'm just putting along and any acceleration I did, the boost needle wouldn't move. I arrive at the store, and when I got back in 5 minutes later and drove off, My boost was back. Truck operated normal for the 25 minute trip home. I thought a similar thread was started but I couldn't find it.

My truck is all stock and I am running in performance tune? And my friend the former owner said I need to let her loose about 75 percent of the time I am driving it because it's my DD and I do not tow anything on a regular basis. I do not want to stretch my bolts by unnecessary pushing, I don't know if I'm even pushing it hard but I normally get the turbo up to about 30 psi is that to much?

Still working on this E450. Now, I'm trying to get the turbo back on and I don't know how the heck to get the oil tube in.
There's so little room that I can't lift the turbo up. Just getting it in and out is a chore. I was able to pull the oil tube out with some difficulty when I was removing the turbo, but if it put it in first, the turbo won't go over it to get back in. If I leave it disconnected to get the turbo in, I have no way to reach under it to get the oil tube back in.
I only messed with it for a little while - it's physically difficult bending over inside the van to wrestle with it - and will go back at it first thing in the morning. I know there's gotta be a way, I've just never done this before.
Do I stick the tube in the turbo first, in the engine, or neither until I got the turbo in place?

In my 2011 F-250, 6.7, auto....it seems that at certain times went the tranny shifts from 2nd to 3rd and I pause with acceleration, for some reason the tranny seems to go into a slip mode and then slams into 3rd. Now I read about 8 months ago that there was a computer upgrade via Ford. Which they did when I was having some work done on the truck at the dealership.

Cold start the injectors definitely are not "clicking" the way they should be. Bought a scan gauge II and checked the FICM voltage and it never drops below 48V. EOT/ECT never really get past 8/9* ....
Issue is when I first start driving you can feel a definite miss, but as soon as the truck warms up it runs excellent, no issues starting hot. I did put 15w40 in it but upon some research I drained it and put in 5w40 syn and it definitely solved some of the issue but it's still there.
One other note the battery's are a little weak in the truck so tomorrow I will have new ones-putting this in as a side note in case it may cause an issue

2005 F250 SD, Crew Cab, Diesel 6.0L...
Hauling my jeep (close to 16,000 pounds all in F250+trailer+jeep) on a highway going a little over 70mph up a hill when I seemed to have lost some power and the check engine light came on. The turbo PSI was well over 20PSI (according to the gauge in the dash). I have a Scan Boss but I have not been monitoring turbo boost PSI.
I was only 10 miles from the final destination so I continued without stopping. It seemed that the turbo was limited for the rest of the trip. Later in the evening, no more check engine light but I haven't really driven the truck since then.
What do you think the problem was? What should the course of action be?

Having this problem, what to do to correct it? There is no hole in the boot and this just started about a year ago. Does not do it all the time.

I have an F450 with a 6.0 turbo diesel with 267000 miles std trans. 4wd and just bought it a few weeks ago. When the engine is cold, the truck runs fine but after driving for 15 minutes, I loose power in 3rd, 4th, and 5th gear. The gauge for the turbo drops from 20 down to 5 and the truck starts blowing black smoke. This starts at 1500 rpms and stops when I am past 2200 rpms.
Before 1600 rpms and after 2200 rpms, the truck has lots of power but withing those ranges, the truck has almost no power at all. When I first got the truck, the problem didn't start until I was up to 1800 rpms. No codes showing up either. I had the truck serviced by a diesel mechanic and the filters replaced using Ford parts. Problem persists and only exists when the engine is warm.

I just recently repaired issues with my 6.0 and now new issues has begun. The turbo keeps blowing the pipes out of the rubber hoses. Not sure what is happening or why so a little insight would be useful.
Oh yeah out of all the work completed in my previous post..don't bother replacing the solenoid section of the injectors. I replaced two the bad ones, rebuilt the other 6 with new everything including a cleaning and now I am getting codes for 3 that are going bad. Oh well I tried right...

Would there be much oil in the down pipe if the oil deal was leaking on the turbo? I broke it loose to look at it and not much there, one small area that looked like it has had on it..

On Friday my turn shaft broke, 70 mph on the highway. As soon as it broke burned oil like a freight train, I know seal in the turbo. Bought brand new Garrett turbo installed last night. Let idle for 5 minuets and went and drove it and it burns oil once I get on it. Drove it for about 3 miles comes and goes? I did break a piece of the turbo vane off 1/4 inch by 1/4. The truck runs fine no knocks or misses. Could this just be oil left over or is there something else I should be looking for?
