I have a 3/8 bolt broken off inside the hole about a 1/3". This is the bolt that holds the alternator to the head. I suspect it's bottomed out. I've tried a left hand drill bit and a Craftsman Drill-Out and I am not removing any metal. I'd sure like to not have to pull the head to remove it.
I'm no drill bit guru but the bits seem to be sharp.
Any suggestions or help anyone can offer? Is it more than drill straight in to get the hole started or what?
