I guess I've been blessed with 2 unicorns. '13 with 190K - never a problem. '19 with 100K - no problems.
I'm knocking on wood right now!
All of mine have been rattle free except for the ecoboost flex I bought used. The last 3.5L was my 14 with 178K. Just maintenance and the vacuum pump started seeping oil at 130K, but that truck was lots of highway miles.
Main thing is to use a good synthetic oil, don't go over 5000,
And do not lug the engine, the theory for more frequent failure oil pressure doesn't get enough to properly lubricate the vct solenoid. So folks that drive the kids to school, rush hour traffic etc seem to suffer more. Of course there are people that do this and have failure anyway. The updated part fixes this once and for all, so I'm hoping this starts to trickle down.
I've been running the 2.7L in my F150s and they are excellent engines, I have had zero issues and they eat up the highway. Averaging 4000-5000 miles a month, so the 2.7 for the long trips and the Lightning for in city/ short out of town trips.
