Recently I stripped out 2 of the retaining bolts when trying replace the coils on my 2015 SHO.. I talked with a local mechanic and he gave me 2 options, he said he could jb weld or expoxy a stud in the insert and then use a locking nut on top to hold the coil down or option 2 replace the valve covers.. He suggested I just fix the studs and don't start pulling stuff off the engine to potentially create leaks or other problems, I didnt really like that sugesstion so anyone know a shop that is familiar with SHOs or ecoboost in general?
