My subjective take is that yes, the Box engine has design flaws and yes, they are more than one might find in a chevy small block or Lexus V8.
The larger issue is the cost of the flaw. I think that gets to the heart of the issue. If one could find a rebuild for three grand or so, this may be less alarming.
If it were me, I would run Red Line Oil and change it out at no more than 7500 miles or 6 months.
