Agreed. That is a bummer about your buddies motor. I think we all have had similar, but not nearly as bad as this, situations. This is the very reason I do my own work. If I do pay someone to do work for me I try to educate myself as much as possible. I wasn’t arguing about your buddies case. I agree timeslips tell the tale although you add a ton variables in there. A big one is torque converters.
