So I'm doing headgaskets, and the only thing left to do is to take the exhaust manifolds out of the car. the passenger side came out fine, but the driver's side is not going well. The nuts that connect the manifold to the downtube are very rusted. I tried mapp gassing it to cherry for 5+ min, and I tried soaking it in pb blaster for days. Eventually, it just rounded when I used real torque.
Because of the 90 deg. cat and the shape of the bracket, I can't get a cut off wheel to the stud or an extractor to the nut/stud. I suppose I could cut the downtube, but not only is that a ton of work with the tools I have, I still want to use the stock downtubes for now.
My next crazy idea is to try high strength locktite on a cheap socket.
Anyone have a better solution?
