Instead of me screwing up Trav's thread on reviewing the '22 Expedition...
...I'm starting this thread about EB's and the backside of intake valves coking as a result of direct injection.
In the Expedition thread above, Travis responded to several questions I asked regarding this issue and my '19 Explorer Sport w/3.5L EB, w/53k miles. I had installed a JLT/OSC Oil Separator on it at 8k mikes. I also do my own oil changes on it from 2.5k-4K miles using Mobil1 and Motorcraft FL500S Filters.
Repost of #12 with Travis's response:
Q: Do you have any concerns about Ford continuing to put this 3.5L EB in vehicles?
A: No
Q: Does this have EB still have direct inject?
A: Yes
Q: Has Ford solved the valve coking issues on the EB?
A: Yes
Q: Does this EB also have the internal water pump?
A: No
Q: Any other observations would be appreciated.
A: The valve coking can be alleviated with 3 things on most new EB engines. First, do 3,000 mile oil changes with a decent oil (I've been running Costco synthetic, but will probably switch to synthetic diesel oil once I run out my current supply). Second, run an oil seperator. Third, on the EB engines that have 2 fuel systems - get a custom tune that utilizes the port injectors much more. They will help clean the valves.
I have a couple more questions for Travis, and anyone else, so please jump in:
Q: Totally understand your point about optimizing and utilizing the Port Injection with a tune. What tune(s) do you recommend?
(It's my wife's DD. At this point, not sure if I want to keep it for the long haul, or bail. It's really been an excellent SUV with no major issues.)
Q: Is this something I can do myself?
Q: Will a tune void the extended warranty I have with Allstate?

Full Size Fun | 2022 Expedition XLT Review The 2022 Ford is all about maximization. You can maximize your capability, comfort, capacity, etc. Few new vehicles allow owners to haul more people and stuff, in more comfort, to more places than the Expedition. Ford recently loaned us fairly rare...
