Turbo Troubles

Im having troubles with my 2003 f250 and the turbo was diagnosed by the dealer as blown. I got a 2004 turbo from a friend that was sure it was ok, but it makes the same noise as my old one, once the rpms go up at 2 a grinding comes from the turbo area, once you let off the throttle it goes away. My truck doesnt smoke and has a little lack of power. It seemed like the guy before me tried to do something with the turbo because the pedastal was cut by an acetylene torch. Im going to re-build my old one and put it in but i didnt want to put it in and that fail, is it possible something from my motor is screwing up the turbo or is it most likely both turbos were bad? Or could it be something totally different? Thanks!

It's probably the turbo pedistal thats jacked up. Turbo droan. What did the po do to the turbo pedistal? Rebuilding a turbo, sucessfully, is not for anyone.

Sent from my phone that somebody didn't help me get.

if the exact same noise was occurring prior to the replacement, it's likely not the turbo. did you also replace the vgt solenoid? or was that still from the original turbo?
are you noticing any drivability issues when the problem occurs? you allowed a relearn? are you noticing any exhaust leaks?
try running the vehicle with the vgt disconnected. see if the noise ceases. you can also try running the vehicle while someone throttles in, spooling the turbo, you listen in the engine bay and try and pinpoint the location.

Ok I appreciate everybody's input. I have a little bit of an exhaust leak at the right side manifold. I have no idea what the past po did to the turbo pedestal, he " jerryrigged" a lot of things that I didn't know about until after I bought the truck. The vgt cellinoid is stock as far as I know, I will try unplugging it and running it. Again thanks for everybody's input.

I now have another question, could it be possible that the oil fill tube is clogged that no oil is getting to the turbo which caused the bearing to throw out causing the compressor wheel to hit the housing, does that theory make sense and if it does how do i check if oil is getting there or not?
