Wife wants to look at a 2017 Lincoln Navigator with the 3.5 ecoboost in it. 110k miles. What is the life of the turbos on these? 150k? 200k? I know next to nothing about these engines.

They'll get you all the way to the tow truck. Pretty much like everything else these days.
They have some issues but I think it's more timing chains than turbos. |

I love by 3.5, tons of power.
I have friends with 300k+ on their trucks. |

Check if cam phasers are updated. Although, if they aren't they would have shown by now.

Don't know why their called "ECO" boost or "ECO" anything. My '17 onefiddy 3.5 EB got 16.8 MPG lifetime and 80% of that was highway. Thing did haul ass though.

My ecoboost, i think it was 2015? Early on anyway got to like 290k before I switched trucks.
It was just developing some rattle from the chain. Gave it to one of the companies kids and he had the chain fixed and I think is still driving it. |

Modern turbos aren’t the turbos of yesteryear that were more susceptible to failure. Water cooling alleviated a lot of the issues that were first seen with turbos as well as better production tolerances of engine parts.
A 2017 would be before the dual port injection on those engines I believe. While I have not heard of carbon build up issues it could be a possibility. As mentioned in other posts the biggest issue those engines face are cam phaser and timing chain tensioner issues. Why ford can’t produce these parts that don’t break I have no idea. If it’s well maintained they are solid engines and you shouldn’t have to much of an issue. I would change the oil long before the recommended mileage. They go through spark plugs pretty quickly. The power the offer is incredible and makes for an enjoyable drive. |

I’m my last F150 the turbos were good at 275K, but there were other issues that were starting to crop up.
I’ve heard of folks with turbo issues at 150K. My son’s F150 has almost 130K and turbos still fine. |

There is EB 1 and EB 2. 2017 was cut off year. That Lincoln, IIRC, has the newer version. Cam phasers are the only real issue. Took until 21 and three versions to get the cam phasers right. Otherwise they make gobs of power and get decent mileage. My 2018 Expedition is 4x4 with 3.73 gears. I get 19-20 with cruise set on 80.

Thing did haul ass though. It's Eco or Boost - one or the other. I can baby mine and keep the boost low to non-existent and it will do great on MPGs. The second boost comes into play, nope. I couldn't care less about gas mileage, but I did want to see if the 17 city and 22 highway they claim is even remotely realistic. So, I drove like my father in law for a couple weeks and I averaged over 19 MPG combined. OP - if the cam phasers have been replaced, it's probably OK. If they haven't and aren't making the telltale rattle, it's probably OK. The stretched timing chain issue was on the previous version of the engine. My '18 F150 EcoBeast has 103K on the clock. Had the cam phasers replaced around 40K and the water pump at 99K. Other than that, it's been great. Knock on wood. I had a '14 Explorer Sport and it had the stretched timing chain issue. All of this was repaired under warranty, thankfully. |

I owned a 2012 First gen eco for close to 8 years. I traded it with 90k on it.
Overall I didn't hate the truck but I didn't love it. It was somewhat snappy when you really got into it but would hard shift in the upper gears if you didn't let off the throttle. I think my truck left the ECO portion of the motor at the factory. I got 15 around town and 12 on the interstate. I ended up trading it in for a 23 Trail boss with a 3.0l Duramax. Pros: Fairly reliable. It never left me stranded and I only did a few small repairs and basic maintenance. Comfortable seats and interior, lots of room. Good looking truck. Cons: Poor fuel mileage. Constantly threw wheel weights. Dealerships and tire shops could never get them to stay on the wheels. Cold start rattle - fixed under warranty (thank god) Shudder issue under full throttle - fixed by drilling a hole in the intercooler Popping noise in the front end that we could never find Didn't handle the best in the snow/Ice |

The jiffy fittings on the turbos will leak way before the turbos themselves fail.

Personally I think a big factor is oil change intervals and full synthetic oil. My 12 f150 has 180k+ and only things I've done so far besides maintenance is water pump and coolant line for one turbo.

Is the 3.5 the one with both port injection and DI, or DI only? Not hating or pooping in a thread, but thinking out loud re the spirit of the OP's inquiry.

21 3.5 EB F150, 106,000 miles. Only owned it about 6,000 miles, but it's nice and quiet. Think they redesigned the phasers for this gen. Gets 11mpg with the 12' enclosed trailer that lives behind it, but I only drive about 62mph.
Yes, mine has dual injection. Not sure how/when they operate, if it's load or boost or drive mode dependent. |

Turbo failures aren't very common.
Cam phaser failure seem about as common as GM trucks with dead lights. |

Oil lines started to leak on my 2015 f150 at 160k miles.
Wasn’t anything to do with the turbos. Just the oil lines corroded out from the salt and shit on the roads. Truck is a reserve in my fleet still. 190k miles and it’s fine. Needed a new set of cats on it because they were throwing a code. |

I'd be less worried about the turbos and more worried about the leaky plastic oil pan and the cam phasers/timing set.
I just dumped my 2018 EB because the cam phasers died for a third time even though both times they were done they were the "updated" design |
