TnP, why do you keep spreading false information? I thought you were better than that. Ford did NOT put port and direct injection on the Gen 2 Ecoboost due to carbon issues. They did it to meet emissions. more power, and fuel economy. I posted multiple links stating this so why do you continue to post false information even after knowing the truth?
Also, just because someone is gullible enough to get sold on a catch can and you post their link, does not mean there is an issue. I was a very active member on that same F150 forum for years up until 2015. There were many members who were sold on these catch cans(even the 5.0L guys with port injection) as "cheap insurance" even though they had no carbon buildup issues and many other members were going hundreds of thousands of miles without them and zero issues due to carbon.
What these guys failed to figure out is that port injected has carbon build up on the intake valves too. This is why some black smoke comes out of the tail pipe when you floor it after driving conservatively for a while. So just because they see some carbon on the valves does not mean it is not normal or is harming the engine. It is when the carbon buildup is causing power loss, compression loss, or other mechanical issues when it is a problem. If the amount of carbon on the valves is not causing any of these issues even at 150k or 200k like many have done, then you are not having carbon buildup issues.
So until you can post where the carbon buildup was causing any of these issues on a regular basis, then I would stop trying to scare people with non issues.
