(shocked) So I was taking off my valve cover, and one of the rusted bolts on the bottom left side BROKE! I got the top of the nut, but the rest with the threads is stuck in the block's threads. I obviousily can't drive and will prolly have to fix this myself. My question is WTF do I do? I have a bolt remover that I can attach to a drill and try to drill into the broken piece and then reverse it out, but its a tad risky. Any HELP would be mint! I need my car for Tuesday forsure. So I need this done ASAP. Help out a 'screwed' mazdonian. Thanks!!!
