Well that didn't work. Didn't make a dent in the broken off part. Think I am going to have to pull the head and take it to a machine shop and see if that can do anything for it.
Question. I just put new head gasket and ne head bolts on. The car has not been fired yet, can I re use the gasket and bolts or is it best to get new ones of both.
Don't pull the head off, if you do your going to have to replace the gasket and the bolts if you used stock torque to yield. Centerpunch that broken bolt and drill through it. Start small and get bigger. Do your best to be dead center in the middle and at the correct angle. Once you get a Decent size hole use an easy-out to extract it. The one time I did what you did, I ended up having to drill the bolt out completely, bought a 8mm x 1.25 helicoil kit from napa to repair the threads. The important thing to know is that aluminum is a pain to tap threads into, so be very careful to not break any tools while working with it. When aluminum gets hot, you break taps easily.
Before I put any engine parts back together I always clean every bolt and chase every thread into my heads. If you don't do that, this is what happens. Good luck my friend.
