Since this is a rather bizarre occurrence, I'm just trying to think outside the box...perhaps I was in the wrong box to begin with, though. But I have witnessed the crank pulley riding on the front motor mount with these engines.
How about: Gyroscopic precession acting upon the rotating fan when making a hard right turn, combined with a worn water pump bearing causing it to bind? Or perhaps acting upon the rotating assembly in the alternator causing it to bind?
Perhaps the fan belt is the wrong width and it is riding too deep or too shallow?
