As the title states, The top half of the BAC bolt snapped in half. as this is my first RX-7 and I am new to both rotaries and car work. is there anyway to extract that nub and put in one of those double sided bolts to replace it? or would it be more easy to break and drill it out and just tap a new one in?. going crazy here because the car won't stay started and its unfortunately my daily. any help would be much appreciated.

Also before anyone asks...yes thats my real name...

 

is there anything left of the bolt sticking out if you remove the BAC? If so, grab some penetrant and vice grips and work it out've there

 

Yea there is, guess i'll try working it out. i'm honestly terrified i'm gonna snap it again... heres hoping.

 

douse it with penetrant, and if you can, heat the metal around it up with a torch, than clamp onto it and work it back and forth. It probably broke because steel bolt into aluminum=corrosion. Heat and penetrant are your friends
