I've heard that other manufacturers have made the return ports smaller than they used to and perhaps this is the case here as well? But with this engine you are reving much higher. I really don't know, I'm just wondering if anyone else has some real thoughts about whats truely going on here. I'm an electronics tech for my profession and typically when something fails it was caused by something else, not the part that blew up. Cause and effect, they don't usually happen in the same spot. Just my thoughts.
I'll add perhaps the oil is cooking at high revs/temps and burning or flashing: re flashpoints
