But that does not mean the phenomenon does not exist.
There are plenty of reasonably credible stores on 'tube that indicate it's been an issue in Ford EB engines way later than 2010.
If this were only a ghost issue, why are there are now major product offerings specific to this topic?
(note - I'm not convinced this is the way I'd solve the issue, but I am merely pointing out that the aftermarket sees a large enough market to justify specific production placement)

Same Ford tech telling us why using a "catch can" can reduce this issue

And it's not just the 3.5L EB engine .... Here's the 2.0L EB

This phenomenon is not limited to 2010 engines.
These examples are not all high-mileage units; they often are less than 50k miles, some even less than 25k miles.
Is this phenomenon present in all engines? Yes, even MPI gets valve build up. But not nearly as bad, and not nearly as soon as an EB.
Not all EB engines have the same magnitude of exposure; I would also admit that.
But for you to imply that because I don't own one, I cannot understand the issue nor comment on it, is silly.
One does not need to be present at, or affected by, a phenomenon to understand it and believe it credible.
The inference I take from your comment is that one must own such a vehicle to be considered "credible"?
I live in Indiana; always have and likely always will. Therefore, I don't live in Houston.
I do, however, understand there's reason to believe a storm front passed through Houston a while back.
Same goes for the central strip of Florida; I hear there was an environmental tussle as well.
By your logic, I should not have any ability to comment on those events simply because I did not experience them directly.
By your logic, I should not trust anyone's assessment if they did not suffer from those events directly.
I find your logic flawed.
I agree. There is enough information out there to know the problem exists, as laid out here. A person doesn't have to own one to learn or know about it. Talking to people with first hand experience, or service writers who deal with it is another great place to learn about it. I have a Ford service writer friend in PA who shed some interesting light on it. Time will tell how the newer engines will do.
