Has anyone pulled their charge pipes or intercoolers on their EcoBoost? If so, did you notice a film of oil on the inside of the charge pipe or oil in the compressor outlets of your turbochargers? Some report their outlets to be completely dry, but I see just as many reports of oil seepage on the charge pipe clamps or oil inside their intercoolers. The PCV and cleanside ports on the valvecover wouldn't cause this oil buildup, there's not enough oil leaving the cleanside port even under boost, and the PCV contents get sent directly to the intake manifold for combustion.
