I'm getting oil in my airbox too, as well as in the drain tube coming off the separator. It seems like it is more oil than would be normal. And I too have a leaking valve cover gasket. In fact the valve cover is still leaking even though I replaced the gasket, put sealant around the plastic half moon side caps, and torqued to spec. I feel like something isn't right. Is it possible that a leaking exhaust valve stem seal could lead to pressurizing the valve cover and crankcase? And that this would cause both the leaking valve cover gasket and excessive vapor/mist coming out the crankcase vent.
I've done a compression test - all 4 cylinders at 120 psi (at 7,000 feet, would be aprox 20% higher at sea level). And I've done a leak down test - all 4 cylinders at roughly 5%.
