I just changed the oil in my 06 uly for the first time since it's purchase a year ago and the drain hole striped . I don't think I stripped it as I was using a torch wrench and could only tighten to ~20 ft lbs before it gave way. My guess is that it had been overtightened by a previous owner. Anybody know what the next step is? Do I have to buy a whole new frame or what?
