So OEM again you attack one of the regular members that offers actual help and advice, but you do not offer any alternative advice. All I get out of your post is "you are stupid but I won't tell you the real answer". Look we already know you are anti torque plate...which makes it apparent your shop (what shop is that again?) does not use them.
Regardless of whether it is a circle or an oval, a distorted bore WILL cause problems with ring seal. I do not see why you keep arguing something that has been accepted in the auto industry for as long as many of us have been alive.
