Hey folks..
Sorry if this is not the right place for asking help. Well, I own a 2008 Ford F-250 with the 6.4L. It runs great, but when I tow my Rhino ATV or load anything, the turbo starts making really high pitch whistle. I believe air leak somewhere, but don't have any clue where to start looking. Can anyone give me some help/ ideas to fix this problem?

Thanks in advance.
