    ya they break all the time. Sometimes without even touching the bolts. I see them in work all the time, where manifolds will start leaking cuz a bolt snapped.
    blown transmissions are about as useful as 97% of the guys on this forum

    Are they breaking on modded engines, stock or both? I'm guessing it's just the heat that finally gets em?

    I see the studs broken on 6.0Ls all the time. Seems the back bolt on both sides is the first to go. My truck has the driver's side rear bolt broken off, doesn't leak so I haven't messed with it. I'll fix it when I do LTs.
