2004 6.0 diesel. Truck runs good until it reaches operating temp. When you try to accelerate the boost falls on its face and pure black smoke. Boost is fine under acceleration when not at operating temp though

Mechanic's Assistant: How old is the transmission? Have you checked the fuel filters?

Fuel filters have been changed and trans was replace few years ago.

Mechanic's Assistant: What is the model of your '04 Ford?

F250 4x4

Mechanic's Assistant: Are you fixing your F250 yourself? What have you tried so far?

Its my sons truck, and I'm trouble shooting for him. A shop replaced all the injectors because he was getting white smoke. that solved that issue. He was showing no boost, traced that down to map sensor tube and replace it, now I can monitor boost. Thinking it could be leak on turbo piping or boots or maybe ebp sensor of plugged ebp tube

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Should be it

Hi there, if everything you mentioned above was checked (boots, ebp, etc.) I would be inclined towarda the vgt solenoid. It works with oil pressure and also have seals that might go bad. This is what directly controls the boost on these turbos. I hope this helps!
