Sheared off bolt

[Jeff H]

I use PB Blaster and a heat gun for stuff that is rusted in place pretty good. It takes time with the heat but keep spraying the PB Blaster while heating and it will eventually expand the metal and the PB Blaster will get into the thread area. It took me an hour to get a turbo to separate but I could see the progress as the combination started to melt the rust and it would run out. Keep tapping the housing with a hammer until it breaks free. Then you probably need to do the same thing with vise grips to get the bolt out of the intake but with aluminum threads it might be easy to strip it. I would probably heat and spray the bolt for a couple of days before trying vice grips to give it a chance to separate.
