Does anyone have knowledge on how to remove the broken studs from the heads? Or does anyone know of a good cheap shop that does this work in the vancouver area B.C. Canada?:doh:I didn't break them off, I heard a leak and it appears they broke on their own.
You could use an easy out. Basically a reverse drill bit with teeth so you can grip the broken bolt and ease it out. Worse case scenario is to drill it out and then use helicoil.
