Thought I would bring something to your attention.
Take a look at this video (There is a part 2 link at the end of the first video, the 2nd video shows what this build up does!):

This one shows what comes out of the catch can after about 3,000 miles:

Here is another quick video (Apparently after 130 miles?)

There is anecdotal evidence that the oil from the PCV system is sticking and "caking" onto the intake valves of this motor. Over time, and as miles start to pile up, that build up on the backs of the valves will cause problems for you. Your idling will begin to deteriorate when the engine is cold.
Using detergents or additives has been causing premature failure of the turbo.
This problem is prevalent on most if not all types of GDI (Direct injection) engines. Some manufacturers add catch cans, others like Ford don't. Fords response apparently is to replace the heads and injectors when these symptoms arise. Well, thats great when you have a warranty, but it takes alot of miles for the build up to cause problems.
Low mileage engines do not experience these problems. It is only after the motor gets 50,000+ miles where the "caking" may begin to cause the symptoms.
Full synthetic oils seem to be helping with this, but it does not stop it completely.
You may want to install some sort of catch can to eliminate this potential issue.
I did some research on catch cans, and the Rx can with the dual check valve seperator seems to be a pretty good set up.
I have a 2013 Explorer with the Ecoboost V6, and I have one of these cans on order. I'll let you know how it goes for the install. There is an explorer specific model not listed on their website.
Certainly not a mandatory thing to do, but it seems to me that spending a few bucks now, will keep this crap out of your engine in the first place, thereby, hopefully eliminating this carbon build up due to burning evaporated oil. These valve systems do not like to burn this oil!
Anyway, I thought this might be helpful!!
