I wonder how hard it would be to add Dual Port Injection to the Ranger to fix the carbon buildup issue. Sigh another thing to do to make it run "adequately".

Big difference between the Gen 1 and Gen 2 EcoBoost engines. 
The walnut blasting looks like a good thing to add to your maintenance if you're planning to keep it a long time. I had a thread on the walnut blasting which wasn't all that expensive for the DYI kit.

might be cheaper to just buy a whole new engine and at least in my mind carbon build up not a worry until it becomes one, one the other hand that poorly designed HVAC is .

THERE IS NO CARBON BUILDUP PROBLEM ON THE RANGER THAT I'VE HEARD ABOUT

Wait for the 2024.

The 2024 next generation 2.3 in the Mustang is getting the direct and port injection to resolve the carbon buildup issues. Hoping that next generation 2.3 makes it into the 2024 Ranger and Bronco platform.

How does 2-port injection work? Fuel gets injected in two places all the time, before and after the valve?

They use a combination of direct injection and port injection and the ratio of each source varies depending on operating conditions. I'd have to see the PCM calibration to quote the blend ratios for various operating conditions. From what I've read, they use the port injection to supplement the direct injection during cold starts for emissions benefits and also use it for power enrichment when you need sudden acceleration.

He talks about timing jobs. This is the timing chain replacement? Does the 2.3 have this issue?
A belt should be replaced but a chain?
Cheers ?

A Toyota innovation according to this article

Very informative.
My favorite line of this article, " Dowding and his Ford engineering colleague Stephen Russ stress that carbon deposits on tailpipes and intake valves have never been an issue in their DI engines.
Never been an issue...

Well I keep in touch with some gearheads I'd occasionally wrench with yrs back and from di engines they have torn down they do see carbon buildup on the intakes, some heavy but hadn't seem to impact engine operation when car was still running. There are of course reports of engines running poorly due to impingement of the intakes (audis, bmw) but it is my understanding that most of that occurred in the early days of gdi and improvements in design that reduce soot and blowby have lessened the risk. I'm not concerned about it, put a catch can on 2 yrs back but wouldn't today, took a trip recently of around 450 miles and the catch can was full at the end mostly water vapor and I don't know whether or not it disabled the pcv flow, I checked the oil level and noticed it was higher than normal so I assumed that it blocked the pcv operation , I've not had gas dilution issues.
