So I'm in the process of turbocharging my car, and in removing the 5 nuts I had holding my exhaust manifold on, I managed to strip 4 of them. ****. Weird, considering I've done this job oh so many times before. I have a feeling I overtorqued them last time I put the mani back on. But what's done is done, time to look for a solution.

So, solution advice? Worst comes to worst, I'll take the head off and extract the studs with the nuts still on them, but I REALLY don't want to do that. I've heard something about an extractor kit that didn't involve drilling or something? That would be nice. Fortunately (REALLY FORTUNATELY) the 4 nuts I stripped also happen to be the 4 that are the most accessible.

Soo.... Any solutions?

The more you turn, the more it tries to grab.

 

Only tool that has ever consistently removed fucked up hardware for me. Nothing else is even worth a second glance. If this doesn't work, you're going to need a welder to repair your mistake.

 

Get a stud extractor kit. It works awesome. Soak the studs in some sort of moovit, liquid wrench, etc.

 

Thanks, that's exactly what I was looking for.

 

Hammer the socket onto the bolt if possible. That works for me.

Cool trick my dad taught us: Use a breaker bar and a wrench. The closed side of the wrench goes over the handle and you use your palm like you're breaking boards in karate.
