03 question HELP!!!

[moosehead06]

Have an 2003 with a 7.3 no mods... in park it seems to run fine until half to full throttle then it starts cutting out and smokeing blue...... while driving it seems to run ok till it starts getting spooled up and pretty much falls on its face any help would be great thanks

[optimus]

its probably the oil seals in the turbo i have worked on several with the same problem the turbo shaft itself may not have any play in it but the seals can still be bad. i have mine rebuilt at a local turbo shop here it costs $400 to rebuild them not bad considering the cost of a new one

but it could also be the injector orings but i'm leaning more towards the turbo.
