You sure the 3.5EB in the Expedition got dual injection in 2017? I thought the F150 got it in 2017 but the Expedition always seems to be a year behind. Our Expeditions often seem to be the stepchild. :)

Yea, probably only the pick-ups got it and probably 2 shorter timing chains also.

From Microsoft Edge;
For the 3.5L EcoBoost V6, the first-generation model (2015–2016) also used only direct injection. The second-generation 3.5L (2017–2018) introduced dual injection to address similar carbon buildup problems, with port injection used primarily at idle and low speeds, and direct injection dominating at higher loads Ford-Trucks.com+1.

Summary:

  • 2.7L EcoBoost: Dual injection started with the 2018 model year.
  • 3.5L EcoBoost: Dual injection started with the 2017 model year.


Thats true for the F-150, the expedition got the second generation 3.5 with the new Gen which is 2018. The expy is a little late to the party.

We have a 2017, definitely no port injection on there.

Four things are inevitable on the later years:
- The turbos will develop coolant leaks
- The header bolts will break
- The valve covers will leak
- The VCT's will rattle on start-up
.... and if your really, really unlucky:
- The lead-frame in the transmission will go out
- The master cylinder will fail
- The water pump will go out

Good news is, if your a good mechanic you can fix all that in your driveway. I have pulled and fixed both my turbos for leaking at 170k miles and put the OEMs right back in because they were fine, so wearing them out is not a concern and the leaking is relatively slight so you can ignore it and just monitor the coolant. The headers are easy but the broke bolts can be a challenge to get out.

Did you mean earlier years?

This is a good list.

2016, 94k miles, obsessive with scheduled maintenance and a “spirited” driver.

No turbo leaks.
Header bolts….a few are broken. Have yet to address…not cheap to fix.
No valve cover leaks.
No VCT rattles.

Lead frame…went out around 90k miles…this wasn’t cheap.
No issues with master cylinder.
No water pump issues.

I think most of mine developed after 120k miles (90% highway). The master cylinder was a safety recall, that I shit you not, went out exactly one week after i got the notice. Luckily on that it was 100% covered except for the tow.

I'm doin the valve covers this week and am going to throw in a new vac pump while I'm in there. This problem is so common there's over 4k covers on back order as of now. Hopefully the temu/ebay covers hold up. The F150 guys endorse them so we'll see.

I have a 2017 and can confirm is does NOT use dual injection. Edge (Copilot probably) is either hallucinating or confusing model year with the year the model actually came out in. I.e. the 2018 model, AKA 4th gen, started selling late in 2017
