Well, I've read about it several times, and it finally happened. For the first time, I tried to do things right. I brought a brand new torque wrench home from work in anticipation of changing the oil, and torquing some nuts. When I went to torque the crank case bolt, it spun before the wrench broke at the recommended limit. (14 lbs I think) I had read about heli-coils, and timeserts, but am curious as to how all of the oil will drain out since when you look inside the case at the threads, they actually go up into the case and they have slots cut in them to allow for full oil drainage. Anyone tried anything else...Right now I'm leaning towards trying a little JB Weld. Then drilling and taping a much smaller hole for maybe a 8mm thread. Will try to make JB Weld surfaced flat as possible. Then use nylon washer, or crush washer with bolt to seal. Any thoughts??????
