Porpoise Hork, everything you stated has been covered. Plenty of folks have looked at the valves (and had to clean them) on ecoboost engines. Others have looked at the CCV side as well. Just pulling off the quick connect line on my truck shows a totally oil coated hose feeding the turbo inlet.
What ford has in place on this engine does in fact reduce what makes it onto the back of the intake valves - however this is not a passenger car, driven lightly from place to place - this is a vehicle that has a high likelihood of being worked hard. When an engine is worked hard (high rpm/load/heat) it produces exponentially higher oil vapor and crankcase pressures and the OEM measures are not enough.
An additional oil/air separator is only an extra measure and a good thing. The crank case is still venting and that air is still being recycled. Here’s the thing - theres a OEM air/oil separator in place on the pcv side but not so much on the valve cover for the CCV tube that feeds the turbo/intercooler. Imho, cleaning intake valves is cheaper than cleaning intercoolers and replacing turbos. My qc connectors come in tomorrow and I’m looking forward to installing a 2nd catch can to keep the air that goes through my turbo and intercooler as clean as possible.

. People are not kidding about how cramped that area is and having to remove oem pcv line by feel. Getting the factory pcv line out is the only bad part, installing the mount, catch can, and hoses went smoothly.
