Dad's 6.0L Blue Smoke

[Countryboy07]

As the title says, my dad's 6.0L is running rough and blowing blue smoke. The odd thing is that it only does it above 2000 rpms. I am confused on the whole thing, because it doesn't do it all the time. When he is pulling with it, 15,000-20,000 pounds, it doesn't really do it, but when he is just driving back and forth to work, it will. The truck doesn't even have enough power to pass someone if you bring the rpms up above 2000. You can put the throttle to the floor and it just smokes more. If someone can give me some insight as to what to do, I would greatly appreciate it. BTW, it isn't throwing any codes.

03's usually don't throw codes. I Would start with checking boost levels. Then injection pressure.

Check fuel pressure to start. Sounds like an FICM or injector issue though

Finally got a chance to look at my dad's truck today. Checked the turbo for end play and everything felt tight. I put my ID tuned FICM on his truck and started it up. It took me about 5 trys to get his truck started. The first 2 times it started and died right away. The last 2 trys it started, ran for about 20-30 seconds, then died. The 5th time, she started and idled rough for about 1 min then everything smoothed out. I thought cool, and jumped in the drivers seat to drive it down the road real quick. As soon as I put her in gear, she had nothing, I had to put my foot in her a little more just to get her to move, so I stopped in the drive and let her warm up for another couple of minutes. I took off down the road and everything seemed to be fine, I just took it slow. I stopped at the end of the road and I smelled burning oil. I left the intake off when I went for this drive and I believe that the turbo is blowing oil out of the compressor housing and getting on the hot engine. I also looked below the trubo and noticed that the lower portion of the compressor housing is wet with oil. It looks like the drain tube is leaking oil as well. Does anybody have any suggestions as to what to do next? Do I need to order him a new turbo, or is there a rebuild kit available? Any advice is greatly appreciated and sorry for the long post, I just wanted to share what I found.
