Squealing 6.7 Powerstrokes. It is a very common issue that the 2011-2016 6.7 Powerstroke will break the rear studs off of the exhaust manifold. This pickup had 3 of the 4 rear studs broken. The fix from Ford is a set of longer studs and spacers on the rear ports to allow for more thermal expansion of the stud before it breaks. This customer is now squeal free and ready to go.
