So I'm working on the timing cover and the intake manifold gaskets on my Suburban, and since last week I got into a jam regarding one of the new bolts to the new timing cover breaking off due to being overtightened. I was trying to do the torquing to spec, which is supposed to be 106 in/lbs., but it turns out the torque specs may have been too much. That or the bolts themselves weren't up to par to handle the torque specs. Anyway, 4 of the bolts broke inside the block while I was tightening (and unfortunately I didn't figure that out on the first one I broke ) and I was able to get out 3 of them by kind of unscrewing them out with an awe. The last one was coming out, but then it became difficult as it became flush with the screw hole, and then it became hard to spin it out with the awe, and I believe it's because I can't get a good angle on it with the PS pump bracket in the way. I also did try drilling it out, but all it really does is just scrape away the bolt, and not exactly drill through it. I don't know if my drills aren't fast enough, or if the bits aren't hard enough against the bolt.
With that being said, my next plan was to get some cold chisels and then kind of crack the bolt free. Is this an okay idea, or should I do something else? And if it's possible, I was wondering if anyone could tell me what the material of the timing cover bolts are. I got the Dorman timing cover number 635-505. Maybe I should get harder drill bits too?
