don't have time to reiterate everything i've done but really quickly:
1. can you get longer drill bits? doesn't matter if you round out the intake mani hole some, it'll still hold fine.
2. wedge a sawzall between the intake manifold and head. the head and intake manifold can be resurfaced back to smooth. the width of the blade (minus width of the gasket) won't be enough to ruin it if you're careful.
3. heat would probably be nice.

Also note, I have been running one of my EA82's with 5 intake bolts, as the 6th one just refused to extract. For that one, I just made sure the 'nub' was gone/filed down and slapped the intake back on. It rattled a little for the first day or so without the 6th bolt but it settled right in quickly and runs perfect now, no vaccum or coolant leaks at all. It's not the ideal solution but that one has held for well over a year now...

i say they're worthless not because they can't remove something - but because they're not very good - anything that a bolt extractor can remove can be removed by various other methods. so it's not worth the risk considering how hard a sheared off bolt extractor is to remove.
high quality left handed drill bits are amazing and worth every penny. but they are hard to get, i've never been able to find them for sale locally. gotta order what you want depending where you live.

Someone here told me to use 3/8 impact on those and they almost never break that way. So far after the usual soaking with PB ect, this hasn't failed me yet. I know it sounds crazy but it works:eek:
Makes sense! I bet a cordless impact driver would work as well. I know for a fact that works on other smaller rusted screws and bolts

You are fighting to turn corrosion all the way up the shank of the bolt.
