I had to replace the crankcase cover after I cracked it by apparently overtightening the oil drain bolt. The bolt was very hard to tighten all the way through, so it was difficult to tell when it was seated. The replacement cover and bolt had the same problem. I wonder if there is some machining defect with the crankcase cover threads. In any case, I tightened the new bolt to the new cover reasonably well, but I left some thread showing, since I really didn't want it to crack again. So far, I haven't seen any leaks.
