Default Re: Over Torqued head bolts =( please help ASAP


I got a 5/16 heli coil, and the drill bit for it cracked the drill hole wall going into the piston...

When I look at crank cases they are 35 bucks without any insides. Is there something that can tell me how to take apart this engine crank case correctly and put it into the other?
