I need to get my honda on the road. I broke 2 head bolts. Machine shop will charge me about $140 to get them out. And they specialize in that sort of thing. Ok, today I was cleaning my block and I noticed that NOT 2 'bolt thread things' are in the block but "3". I think that mechanics from the previous owner broke one. I dropped a screwdriver into all the holes to tell which ones broke and noticed one on the upper left. I put my original bolts in just to chase the thread clean it up and yep the one on the upper left does not go in. My plan. To get broken bolts out my self. Get a drill and some tap bits and just handle it. I'll figure out how its done proper and all. And then to reuse my bolts again only being super duper carefull. I'll buy 2 bolts $20 bucks from honda rent a drill and get some tap things and just take care of it. Its possible that bolts first time broke because thread is not clean inside the block.
