If the bolt is stubborn and a typical screw driver won't work you can try an impact screw driver (unsure of actual name) to loosen the bolt first.

This has also never worked for me either :( The slit ends up just stripping itself. I definitely wouldn't risk cutting into the housing to attempt this method.

If the bolt was stuck enough to shear and snap a screw extractor, this probably won't work either

Its around 35$ at a machine shop and they will hook it up to an electrolysis machine and melt the bolt out. Then you can tap the hole yourself. If you only tried one machine shop then call around some more and figure out who has the machine to do it. That is your only hope. Please do not try to dremel it out.

The machine shop I went to won't attempt it, I would pay them to do it, but they want to disassemble the motor and get that iron on the drill press cause they said the motor wont fit on the table. On top of that, everyone around here works on cylinder motors and they won't attempt to take apart this motor since they aren't familiar with it. As far as a electrolysis machine, they didnt mention anything about it....means they probably don't have it

Are you saying there is only one machine shop in your area? Call everyone in the phone book before giving up. There is no way you need to take apart your motor to remove a bolt. Rotary engine or not does not matter a bolt is a bolt. Its stuck in cast iron and the bolt is steel. Same thing with my turbo manifold and I had 3 of them melted out.

bolts out, had to use a million drill bit, but its finally out and could probably use a re-tap but its holding the manifold in tight. Put the motor together except for a few hoses and should be ready to drop back in the engine bay

Thanks for all the help

Run a tap through it before you install. It only takes a few seconds.

LOL me too +2 dang ez out broke off after I spent a few hours drilling a hole in the stud.
