How do you drill out and re tap a screw that is broke off? the screw is very very tightly in the manifold. I have never drilled and re tapped before so can anyone tell me step by step what to get and how to do it? Oh and the bolt I am trying to do this with was a 15 mm socket size if that helps to determine the proper re tapping size.</p></blockquote><p></p>
