I was gonna put this in exhaust, but I'm sure the general section would be faster. ANYWAY, I was removing my exhaust manifolds... There are two nuts I can't get (the passenger's side ones closest to the firewall). I stripped the second one to the farthest back... I don't know what to do. It's really frustrating and I'm all beat up and bloody fighting with it. I'd also like tips on how to remove the very last stud if you've got em.


I'm going to search the forum

 

get out the dremel and cut it. if it is hard to reach dremel makes an extension that is flexable.

 

wow that's a great idea
but I don't have a dremel and I don't know anyone offhand who has one.
should I try some visegrips or will that make it worse?

 

when I pulled mine to install headers, I had some stripped bolts on the manifolds, visegrips work, but make sure you are using good ones, I.e., sharp teeth in the jaw

 

Using six-point sockets can make a world of difference. With the metric ones available can also use a slightly undersize socket for less slipping.

Yes and Yes to RBob's inputs.
Can also consider using some PB blaster if they are rusty. When nuts/studs get to that point, any little bit helps.

 

dont have a dremel everyone should have one.

 

I've soaked the whole manifold in PB blaster
and I don't have a 6 point that will fit in there

I got the rearmost bolt out today
I had to cut the stud down with nothing but a hacksaw blade (no handle or anything, just the blade!)
Then i put a shallow socket over it and it broke free and turned.


The other one (the to the right of it) I ended up rounding off EVEN MORE with a pair of vise grips.
it's a complete circle now; No corners at all.
I started to drill at it from underneath it, perpendicular to the stud.
It got dark so I came inside.



Anyway, I started it up with one header on, and one manifold on.
I noticed the header got warm after maybe 5 seconds of runtime...
considerably warmer than the manifold.
This should be fun

 

If you can reach it, try using a center punch around the rounded nut/head, in reverse rotation. Sometimes the the bolt/nuts rust solid to the manifold. A big cold chisel will also work to break it free. Run another bolt in the manifold finger tight, just to hold it up, while striking with a hammer. If the head breaks off, then you can try visegrips to get the rest out. Good luck.

 

An air gun and cutoff wheel work well, I had to do that to one of my manifold bolts. It's my favorite tool for removing stubborn fasteners...

 

I got it by drilling the nut in a few places, and then using visegrips to rip that f**ker off. I'll take pics to show you just how rounded it was maybe

 

Someone isn't paying attention.

Vise-Grips just don't work very well for actually gripping anything. They're great as welding clamps and general pliers, but the jaws are far too soft to hold anything for turning.

If you have room for Peterson Vise-Grips, you have room for ChanNelLock 410G pliers. They will turn anything a Vise-Grip will turn, and far more. The jaws are as hard as a wild boar's ****, and will automatically tighten on the item in them by leverage design (NOT like those P.O.S. RoboGrip pliers!).

"Regular" ChanNelLock pliers aren't the same. They must be 410 (or their larger version, 414). Knipex is a German company that makes a similar design in some smaller varieties, and they're almost as good.
