Stripped intake bolt stirs big problem..
OK I'm replacing the intake manifold gaskets and ran into two stubborn bolts! Ive snapped three torx bits and stripped the bolt. I then tried to extract it but the stupid extractor snapped!!!! Any ideas on how to get it out????

It sounds like the last time the gaskets were replaced antiseize was not applied to the bolt threads and the bolt has gauled the aluminum. This could lead to a very big problem.
It would be best to use a impact torx. Extractors are brittle and will break. I would try PB blaster on the extractor and let it sit over night and try vice grips or a cold chisel with a hammer to back it out.

Safety glasses are a MUST, if you try this.

well good news! i picked up a set of bits from Irwin tools. They cut into the head and twist them out. I put one that was a little small for the bolt and beat it on with a sledge. Twisted right out!
