Has anyone heard a engine or turbo noise in the engine compartment that sounds like a vacuum leak or maybe a air leak in intercooler tubing. The noise is annoying upon acceleration when the boost is around 5-20 psi it’s been getting louder as time passes . It’s there at all times . The trucks runs great and the fuel mileage is great . Maybe this is normal? Because I never owner a 3.0 l Powerstroke I’ve had diesels with and with out turbos I know know this variable pitch might sound like this . Just looking for some help before I bring it to dealer . Thanks

I bet you have a leak somewhere in the turbo plumbing. Mine is pretty quiet and it has never been "annoying" so perhaps the dealer is your best bet. Some others may have a better grasp. Best of luck on getting it right for you!

I hear my turbo all the time, sounds like a wooshing noise under certain conditions, I hear it more when the air is cool. I think it's just the design of the intake. If you put your head by the intake when the engine is on, you can hear how loud it can be. I don't see any signs of leaks for me, but some of that tubing is pretty hard to check. If you have someone rev it for you with your head under the hood, see if the sounds is coming from the intake on the drivers side, or if there are any leak sounds around the turbo.

Maybe talk to @fharrison about Squeal While Accelerating = could be related to faulty EGR ByPass Valve recall(s). Did your truck always do this since new? Or did it start happening post-recall work?
