I noticed that I couldn't thread the bolts by hand so I used a wrench to put the first one in and about 2/3 of the way in the head snapped off. I wasn't even applying much torque... The bolts are as old as the car so I suspect that's why it was so weak.
The service manual says that those bolts get tightened to less than 10 foot pounds. I'm assuming there's something special about the threads on the engine-side that prevents them from falling out due to vibration. Could this be why they're hard to tighten?
That being said, I have to remove the broken bolt so I went and purchased two types of extractors. I got the traditional reverse-thread drill bit and a set of "Grab-IT" bits. Any idea which one will work better?
