well, the second part only broke due to just a weak screw, the wrec has no stress on it what so ever and the head just snapped off of it, im think after it idealed real low for around thirty seconds it switched and ran backwards about 5 seconds before it quick, and I think that is what stressed the head on the left handed screw to snap off. you can see on the little illistration on how the con-rod looks now after the screw ate into it a little, took a polished it out but you can still see where the mark was it you look real hard.
