Could the apparent lack of oiling problems in the 3.0L engines also but due to them being used in vehicles not likely to see high lateral G-forces (Taurus), or being mounted longitudinally (Escape)? It seems that the majority of engine failures from oil starvation which have been chronicled on these forums happened during or shortly after high-G right hand turns (though my own engine failure had nothing to do with that).
That high-G rught hand turn would pull the oil away from the pick-up, and the high RPMs and low oil drainback volume in the heads would further reduce the available oil in the pan.
Several elements here, but they add up to one disaster.
