I’ve seen a lot older posts about a similar issue. I’m posting about mine just to see what everyone else may have found. But when accelerating, a loud squeak/squeal occurs and then stops when letting off acceleration. Have seen a lot of possible Exhaust Manifold posts and answers but just curious
YouTube it, I can say pretty confidently that it’s your exhaust manifolds, Mine went out around 90k. Ford used 6 studs and the block has room for 10. BDD uses all. Think about new turbos too at the same time, same amount of labor. Good,luck.
OP if your exhaust manifold studs are broken it's probably the one at the farthest back according to YouTube vids. Mine is squealing too (2016, 74k miles). I took a look at mine and found the passenger side broken off and the driver side very rusted. Passenger side back position broken off Driver side back position very rusted
