After a nice long weekend at Fenwick Island, DE, I had a little time to start on the head work for the Ricer’s bent valve issue. The first item I wanted to get done was to remove all of the intake and exhaust studs from an old LS head I had sitting around. To remove the studs, I just double nutted the stud, put some heat to stud and a little PB Blaster, and they spun out with little issue.
Once that was done, I took a look at the head I got from eBay and noticed that it had an exhaust stud broken off. Not too happy, but it gave me a chance to try a procedure that I read about but never tried. I cleaned the broken stud the best I could with Acetone and found a nut that had an inside diameter roughly the size of the stud. I broke out the welder, and with the nut out of the way, I built up a little tack weld on the stud. I placed the nut over the tack weld; then, I used the welder to weld the tack to the nut and made sure it was a good weld. With my fingers crossed, I used a wrench and turned the nut welded to the stud, and with success, the broken stud spun out with no effort. I always read that the heat from welding also helps to loosen up the broken stud, and with this experience, I cannot disagree.
