How would you attack this snapped off bolt?
So I go to take the intake manifold off and the first bolt I touch snapped off when I sneezed! It most have been rusted nearly completely through. I have already soaked the thing for a few hours with PB Blaster and tried locking vise grips on it. Any other suggestions?

i drilled threw mine since it just comes out the bottom and hooked a bolt to the bottom when i put on my new intake manifold .. i tried other stuff and it didnt wanna come out .. i still have a broken bolt in the back that i discovered taking it off,so i know someone tried to tackle the plenum before me. the bolt didnt even had a head on it

if you have a welder, you could weld a nut onto the top of the broken bolt, then apply a wrench to the nut, combined with penetrating oil and heat.
and/or i'd try a plumber's propane torch, applying heat to the bolt, then try to turn it with the welded nut or vice grips.
also, if you don't have a welder, but do have a die set, you could attempt to cut/fix new threads on the broken bolt, then thread on a couple of nuts and lock them together.
heat's going to be your best friend. it stretches the bolt and breaks the rust lock.

I've actually had really good luck with these things. Might be worth a shot. http://www.craftsman.com/shc/s/p_101...yword=bolt+off
Welding a nut to it would be the easiest if you have a welder. Anybody ever tried that with JB Weld?

well if you didnt destroy all of the threads on it i would have told you to get 2 nuts and screw them on, back the 2 nuts together and back it out.
but the best thing to do now is grind it in to a square and put a socket on it and take it out, or get a socket that smaller then the bolt and hammer it on, or jbweld a nut

Two nuts is a good one too, just crank on the bottom nut and it would lock together with the top one.
