See picture.

Any ideas on how I can get this out? I do not have a welder, so that option is not in play. I am spraying DB blaster, have tried heating and locking 2 nuts together, still nothing.

If I cannot get it off, I will probably just go to a salvage yard and spend the $50 on one.

Thank you in advance

 

pull the manifold, drill the stud out, use a long bolt in its place

or, buy headers.

 

Thanks Bill. That was what I was going to do tomorrow. Just thought I would ask to see if anyone had any tricks before I started drilling.

Appreciate the advice. Have a good night

 

I don't know if you've done anything with it, but if not, since it's been soaking take a hammer and hit it a bunch of times, it will help loosen it up. Grab it tight with a big pair of vise grips and try turning it back and forth a little bit till it starts moving. If that doesn't work heat it with a propane torch and when you have it good and hot melt some wax against it, it will wick into the threads and will likely help loosen them, then try the same deal with the hammer and vise grips.

If you can't put a torque on the bolt without putting a bending force on it, try clamping the vise grips as close to the flange as possible, that will give you less chances to get it out if you break it there, but against the flange you will be less likely to bend it and break it.

If "I do not have a welder" is that you were trying to weld a nut to it and that doubling the nuts didn't hold them tight enough, you can try putting a nut on the threads, then start whacking the end of the stud with a hammer to deform it so the nut can't be backed off, but typically that will just break the threads off.

If you end up having to drill it get yourself a flat surface first (file it flat with the flange, or if you have room drill from the manifold end that should already be flat). Get a good center punch (possibly start with a ***** punch) and try to center punch it as close to centered as possible, then drill it with a small drill bit and go up in size from there slowly (this will have the advantage of that the smaller bits will go through the center of the stud that is not as hard easier, so if you step up in small steps it will tend to better center the bit as you drill since the bit will try to stay in the softer steel). If you're very careful you'll be able to drill the stud out leaving only the threads which you can pick out with a pick. If you have left hand drill bits use them, as you drill out the center of the bolt it will heat up and you will relieve the pressure on the threads at the same time, and the left hand turning bit may back it out while you're trying to drill it out.

you could try an ez out of sorts but I've never seen one work on this kind of thing. Typically they break off in the bolt resulting in a super hard piece of steel that you can't drill through easily and you have to shatter out or use carbide to cut out.

 

Thank crossfire. I was able to get it out last night. I kept spraying it with DB and then hitting it with a hammer.

Took vice grips and was able to remove it. Calling Summit Racing today and try and find the correct bolt to put in there to replace. Advance, Auto Zone and any hardware store I have looked at either do not have one long enough or have one that I would trust that will be able to take the type of heat it will experience
