100% sure. The oil could be from blow by and accumulated in the turbo exit. common with direct injection, not just ecoboost engines.

"Turbochargers operate at high speed – up to 170,000 rpm – and under intense temperatures of up to 950 degrees Celsius (1,740 degrees Fahrenheit). Some previous-generation turbos were reputed to suffer from oil coking, in which they would bake their lubricating oil. Because oil coking can lead to premature turbocharger bearing failures, Ford’s advanced engine engineers specified the use of new, water-cooled turbochargers to combat this problem."
