So, I was using a torque wrench for the first time. It worked fine on my plugs, but it didn't "click" at the setting of 10 for the head cover bolts and I broke one in there. I tried to stick the head back on and unscrew it but it just won't stick on. I tried to drill it but it's too tough to drill. Do you guys have any suggestions on what to do with it? The cover will stay on with just the other bolt, but I would like to have both bolts on if possible.
