Screeching Noise From Broken Exhaust Stud, 2011-2016 F150 and 2015-2017 Expedition

- Some 2011-2015 Ford F150s and 2015-2017 Ford Expeditions equipped with a 3.5L Ecoboost may develop a screeching noise upon heavy acceleration. This noise may be due to a broken exhaust stud on the rear of either the right or left, or both, exhaust manifolds. In this video I discus this issue. I describe how this noise is created by exhaust back pressure escaping through the multi-layered metal gasket that goes between the exhaust manifold and the head. The broken stud at the back of the manifold allows for this back pressure to escape through the gasket. I also, describe how this issue can be easily checked. I then go into a few methods for repairing this issue.
Note: This is not a "how to" video. This video is simply informational at best. Please refer to a reputable repair manual suited for the vehicle you are working on for repair information. Furthermore, this video does not go into how to safely lift and support a vehicle for inspection. This information must also be obtained from a reputable repair manual.
Of course, stud extraction will have to be performed to get the broken stud out. Usually the stud is broken in a way that you will be able to grab onto it with a stud remover to remove it. However, in some cases the stud will have to be extracted in another way.
Warning!! Be sure your vehicle is totally cool before inspecting or working around the exhaust system. Exhaust systems get extremely hot!

Thanks I’ve been pulling my hair out trying to figure my squeal out.
This freaking guy- best way “ take the cab off”” sure sounds pretty straight forward …. Good night
Question for you on this- how imperative is this repair? I’m going to take it in as soon as possible, but I do have a little trip this weekend that I need my truck for. The shop more than likely won’t have a time slot available for another week or so anyways.
very helpful.
Thank you
Would this cause the traction control light to come on with lack of performance I suspect my turbo but this is the exact noise I have
Its the rattle im hearing in the video also from exhaust bolt?
I’m not sure what you’re asking. Can you clarify? Sorry for the inconvenience.
I have a dumb question, say I was feeling really cheap, couldn't I just change the broken bolt and the gasket and reuse the exhaust manifold?
Oh, that's not a dumb question at all! Yes you could if the manifold isn't warped too much. But, it's such a nasty job. Do you really want to have to do it again? Sad to admit. I'm cheap at times myself and don't perform the correct of most robust repair. But, that's on my own vehicles. If it's a customer, they are getting it done right.
@@BarboursAutoHelp Thanks for the speedy reply. I appreciate it! My truck only makes the sound very intermittently and I'm the type of guy who works on my truck for fun lol. I was going to spend the $200 on a little mig welder so I can weld and nut to help extract broken manifold bolts instead of buying new exhaust manifolds. If I have to do the job again no biggie.
Is this common on the generation b4 this? 2006
No
