jesujoma, I just had to remove a broken grade 8 bolt in an aluminum block. I had to do a lot of searching online, and came up with this:

-If possible, try some heat first; this may break the corrosion bond.
- Get some left-handed drill bits, if needed.
- As you mentioned, the correct size E-Z-out.


I had to get a right-angle drill, but you've got enough room for a regular variable speed reversible drill, should you need it (i.e., if you have to drill a somewhat larger hole through that bleeder screw to fit an E-Z-out). Just the vibration and heat from drilling was enough to break loose the bolt from its hold on the threads in my case....and because I was using left-handed bits, when the bit "grabbed" a little, the problem piece started to unthread.

Since the bleed screw is physically all the way in, I don't see where using a regular right-hand bit will hurt, should you have to drill out the center of the bleed screw a little.

By the way, I recommend propane gas. I don't recommend using MAPP gas unless you're comfortable using it; you could (possibly) melt some aluminum. Good luck.

All true. However, you'd be surprised how little corrosion it can take to make one of these little guys almost unmovable.
