The 5.0 does have the same issue, as do all direct injected engines venting their crankcase gasses through the intake manifold. But with the 5.0, you can use a top end engine cleaner on it to clean it up that you cannot use on the ecoboost engine because the top end engine cleaner will overheat and destroy the turbo seals leading to turbo failures. So the ecoboost must be prepped in order to give long life without issues.
The first thing to do when you bring any air to air inter cooled turbo home is drill a 1/16" weep hole in the bottom of the intercooler to prevent misfires. In the ecoboost's case on the F150, then you want to pop the plugs out and gap them to 0.30-0.33 so life is easier on the coil packs and emissions system.
Finally, bypass the engine evaporative emissions system that carbons up the backside of the intake valves with the biggest catch-can with check valves you can get your mits on. This is superior to the stock system since it puts engine vaccuum on the crankcase and forciby draws crankcase vapor into the catch can. In my case I then added a drain to the catch can so I can open a ball valve and drop the contents into an oil pan, glass jar, or whatever. I also relocated the horns so it would all fit behind the grill with my stealthy 30" behind-the-grill-lightbar.
Do all these things and you're ready to live out life as a rolling F150 commercial towing 10,000 pounds down the highway at 70 mph.
