So, dropped the upper oil pan and removed oil slinger guard. Nothing i can see from underneath. Pulled spark plugs and they look great. After seeing some serious metal pieces in the oil pan, I would of thought it would have been reflected in that cylinder's spark plug. There is most likely a spun bearing. I was just thinking total destruction.
My money is still on oil gallery gasket caused dropped of oil pressure. It is a 2010 @38K miles. Interesting though, my 350z nismo at 39K miles just started symptoms of the oil gallery gasket problem. I was lucky enough to notice it and get it fixed. This is due to the 350's having oil pressure gauges.
