LS broken exhaust manifold bolt extraction

A common issue with the LS engine is broken manifold bolts. In this video I use the ProMaxx Mikey II to drill and extract the studs from the cylinder head. Made in the USA the Mikey 200 series includes everything needed to extract a broken stud, with the addition of the ProTap you can also use a precision tap to align and clean the threads. Here is a great write up from ProMaxx on making room to remove the back exhaust stud: https://www.promaxxtool.com/articles/...
