here's how I worked a broken CAB bolt out:
1) soaked with PB Blaster.
2) used a dremel with small cut-off wheel to grind a flat slot in end of broken bolt.
3) heated broken bolt with torch (an effort to 'scare' it out and to temper it)
4) soaked with more PB Blaster.
5) then I took an inpact driver with a flat blade in the slot made in in step 2, and pounded that fucker out.

PB Blaster is incredible stuff. Truly, truly amazing. Doesn't work so well unless it can get in there in the threads, but I have not broken a bolt since I started using it liberally and soaking for a day or two before going to work. Impact wrenches help a lot too to save bolts. Leaning on something with a breaker bar is way more inclined to snap a bolt.
Left hand drills are the way to go. Just be very careful you don't break one of them, or you have the same problem you have with the easy outs - hardened steel that is a lot less inclined to be drilled out.
Just keep stepping up the left hand drill size until you either come close to the bolt tap size or the threaded part backs out.
If you have access to a welder, another option is to weld a rod in there, weld a nut on the rod, and try again.

there's "Easyout" (EZ out) and there's a lot of the same products called differnt names.
steps:
-NO OIL, NO DREMEL, NO HEAT. PB Blaster Before drilling okay.
-drill with a small drill bit right through the center 2-3~4cm so that the smallest or second smallest EASYOUT bit can be used
-Tap it in with a hammer...like a man.
-Twist bolt out using adjustable wrench or vice grip. should work 1st try...i've gotten exhaust manifold-block bolts out this way. rusted brake bolts u name it this is THE way.No more e30s for me.

Dude you have got it right but I would not use cresent wrenches, The hardened steel will crack off the edges of the square drive end off the ez out. Use either a tap wrench or a 12 point socket that fits the end, or there is lesiley (sp) tools new tap sockets.Originally posted by FusionIf a car is the epitome of freedom, than an electric car is house arrest with your wife titty fucking your next door neighbor.
