Snapped off an exhaust bolt
 

I was removing the nuts from two bolts where the exhaust pipe bolts onto
the exhaust header. I had used some WD40 on them and got one off with
no issues. I was loosening the other nut when I applied a little too
much pressure (but it wasn't a lot) when the bolt snapped on me. I was
going to replace the bolt and nut but realized that the bolts seem to
built into manifold itself. What's the best course of action to take
care of this problem? It is an 88 Wrangler.

blue wrench AKA oxy-acel torch
Do you have enough meat on the bolt to grab with Vise-Grip pliers?
I am not sure if a MAPP torch will get things hot enough or not.

Re: Snapped off an exhaust bolt
 

Get the torch out and heat that sucker up red hot. Be VERY careful with the
torch. You don't want a red hot bolt falling on you. It never fails to fall
into your shirt and to a place that's very hard to remove. Add this to you
squirming around below your jeep which is probably on jack stands. Bad
combinaton.

If you've got enough meat to grab, try vice grips. Otherwise, get some left
hand (reverse) drill bits and start drilling in reverse. Torch it as needed
to keep it red hot or real hot. If it doesn't back out by the time you are
halfway through the bolt, try an EZ-out.

Use a center punch to start your drilling so you don't drill booger up the
threads. If there is some sticking bolt sticking out, but not enough to
grab, try to grind it as flat as you can, this will make drilling much
easier. Use a bit just a little bit smaller than the bolt and once you drill
all the way through you should be able to collapse it.

Let us know what you try and what works for you.

Re: Snapped off an exhaust bolt
 

Next time use a GOOD lubricant like Kroil or BP blaster. WD-40 is a
water displacing solvent that has little effect of tough rust.

For this time, I'd hit it with the Kroil or PB, let it sit for at least
10 minutes, heat it up some, more PB, let the pentrant soak in. Grab
with vice grips. Drilling out is a very last resort. The bolts have been
temp cycled so many times they are hard as files. (and just as brittle,
that's why it snapped). Grind the head as flat as possible, center
punch, drill with a LEFT HANDED drill (if possible other wise a right
handed one), lots of pressure, very slow speed (250 rpm is about right).
You may need a couple of different sizes, drill until you hit the wall
on one side, pick out the pieces. Miserable job when working upside down.
