Copper Manifold Nut (Having issues with removal.)

Any tips guys? I'm trying to stay calm. I have the copper nut that won't come off that is just stripping and the exhaust plug cap seized in the manifold with a broken allen key in it... Seriously, I've got my tail between my legs on this one. I've already ordered new plugs and nuts. Now to get them out/off... I'm so sure who I can take the manifold to, but guessing not much will get done tomorrow. Thinking muffler shop? As to the nut, I've got no tricks up my sleeve.

If you dont have power (air) tools, then you will need a small chisel and hammer along with some patience and perseverance to get them loose. You will likely need to work it around a few turns with them if they are galled/seized. Make sure you apply a penetrant oil to them before and during the removal.

When you put a new one on, use high temp antiisieze on the threads, not sure if it'lll hold up over a long period but next time around if it makes removal even a tiny bit easier can't hurt.

I am putting high temp grease on immediately bought that before hand. Issues with this bolt is the clearing, I will post a picture. I'm going to grab some liquid wrench and a butane torch. I will also see if they have those tools in a wrench form, sockets don't fit in there. Thanks for the recommendation, this will likely work on the stud bolt. The plug will need the torch probably.

Whats worked for me in this situation and i"ve done it a lot. I do repair cars for a living so got decent tools. You will need to get a good quality and narrow bladed screwdriver ideally a Snap-On one as they have a good shape at the tip and are strong. If you can wedge it under the nut, apply a bit of gentle twisting pressure as if removing a screw and while maintaining the pressure try and wind nut off with a quater drive slimline ratchet and socket. I am assuming its the small 10mm nuts that attach the header to the cylinder head,there are 3 nuts,that you are talking about. If its those nuts then any heat treatment will be pointless. Either the thread in the nut has strippd or the stud has stripped. Either way you are trying to get the nut to make a purchase on a bit of thread remaining. Once it bites,you can usually wind all the way off and jobs done. Hope that helps and good luck. Keep calm and think about it,you will do ok.

I got the plug out, I'm going to have t re-tap it. At least it's out... Sears doesn't open until noon, so I have to wait. I'm going to try the nut cracker sockets, if that doesn't work I can try a chisel, and if that doesn't work... The nut is copper so I will cut it with a dremel until it is weak enough to crack. I'm just going to have to take my time so I don't nick the stud.

What do you mean by "just stripping"? Is the nut just rotating on the stud and not screwing off or is the took your using slipping on the nut because its rounded off?
