OK, I have 3 broken exhaust studs on my 2.7 six. All but these three came out easily but these 3 were never going to move! I spray (for several days) with PB blaster, used a torch and nothing worked. Finally I bent one on purpose because I was at my wit's end and eventually broke it. I went ahead and cut the other two off in preparation for drilling. I have drilled out the originally broken one and tried using an "ease-out" but no luck (of course). I'm at the point where I can actually tap the hole for the original thread size. What size tap do I need to buy?

OK, here's what I've done so far:
-drilled out (but not completely) one stud. I say not completely becuase I haven't been able to see the original threads when looking inside the hole and a stock stud is slightly too big to fit into this new hole. Also, the EZ-out that I've been trying to use won't budge anything. By reading that one might think I just haven't drilled a hole large enough to see the stock threads yet, but it sure seems like if I go any bigger I'll have to use a larger stud. I thought at this point I could just try tapping the hole since I'm already at a point that is close to the stock stud size.. Hell I might have already drilled away the stock threads but I don't think so. The inside of the hole just looks like smooth metal, and I've kept a close eye on it and went slowly. Doug C |
