This bolt is really quite stuck. Knowing how much force it took to shear the bolt even after liberal use of PB blaster, I will not attempt an ez-out. They break-off too easily and then I can't drill it.

I read about the wax trick and think I will try it too. My concern with the wax or penetrating oil is the lenght of the bolt; there's at least an inch of bolt before we even get to the threads. This will make heating less effective as well.

In either way, I will be heating very soon to try and loosen it. May try cycling heat and dry-ice cooling but I worry about the allum cover's proximity...

last resort before I drill is to weld a nut to the stud. Some folks say the concentrated heat from welding can loosen the bolt, and I'll have the nut to turn the fastener; but arc-welding on the engine is a difficult affair with the ECM etc...

I hate when this happends...

Thanks.
