Then I carefully clamp the needle nose locking pliers on the end of the exposed stud and GENTLY rock it back and forth ever so slightly. If you get any movement whatsoever back and forth the rest will come, if you're patient. Repeat the heating and shock cooling process followed by the locking pliers as many times as it takes. With patience and luck the broken stud will progressively unscrew a bit farther with each application of heat and penetrating oil until it will unscrew all the way. <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><o:p> </o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>I did this recently with a BJ8 Manifold where 7 of the 8 studs were frozen and/or broken off.
