I have been spraying my midpipe to exhaust manifold nuts with pblaster now since fall off and on. I could not get these nuts off! Went and bought a air compresser, got one nut with its stud off. could not get any more off. Applied heat to other drivers side bolt, got nut off but damaged threads doing so. Passenger side no joy nothing but broken tools. Am I totally screwed or are there any options? I'm thinking of abandoning this project for the summer.
