I have 97 Ford Explorer sport, I'm working on replacing the EGR valve. The two mounting bolts came off easily but the flange nut connecting the tube to the valve is seized up like its no bodies business. Assuming it's pretty much welded itself into the threads from the heat of the exhaust recirculating, how can I break this nut? I've soaked it in PB blaster, used some stuff called freeze off, neither of them have budged this thing!!
