TURBO SOUNDS LIKE JAKE BRAKE

I bought "forina" a 2005 6.0 crew cab with 26000 miles and now she has 80,000. From the time I got her whenever you get into the throttle and then let off it sputters like a jake brake on a big truck. It sounds like some kind of blow by that can only escape when you let off the throttle. Ford dealer told me i need a new turbo but then said they couldn't replace it under warranty because the computer didn't say it was bad. Of course now the warranty is expired and the local dealer has no clue what is wrong. I've been told that it sounds like the waste gate isnt opening properly, and I've been told that's not possible because I dont have a waste gate. Please help

Turbo Fart? Does it do it just for a second or two after you let off on the throttle? If so, that is normal.

yeah its only a couple of seconds. kinda like chu chu chu chu. the other thing that it does is when you get into the throttle and then let off... when you try to accelerate again it wont boost. it will make a muffled bogged down sound and wont get up and go until you let completely off the throttle for a second and then try again.

The chu chu chu chu chu is normal. The other problem I am not so sure about.

I would clean the turbo and if the problem persists it could be your VGT solenoid.

Would a BOV stop the "FART"? I have heard it not good on a
turbo.

generally, diesels shouldn't need a BOV, since they don't have a throttle plate
