i have a 2002 7.3 and it seems that the problem is getting worse. my turbo makes a loud howling noise. it doesnt do it all the time only happens after i have been driving on the highway for a while or if i slowed down and quickly sped back up. i have taken to the dealer in the past and they have no clue what it could be. i do have the banks turbo upgrade on there but i dont think that its causing the problem. does anyone have any ideas what i could be?
