Longevity of the 2.7 Ecoboost?
 

Bought a 2017 with only 14500 miles on it. My buddy posted on FB that he has the same truck with just over 100K on it. He's on his second turbo...the first went out at 60 K. Is this a common problem? Didn't find anything with my searches. Seems like a solid motor to me. .??

I've only got 15000 on my '15, so I'm no expert on the longevity.... but I've seen several threads in the past with guys over 100k & the motor was still going strong. But there are also guys with '17s (sorry) who have had to have their engine worked on multiple times...KillinTime is going thru this now

I bought a 2017 with 23000 miles on it. She now has 47000 very trouble free miles. The truck is awesome!
:clap:

Just picked up a 2016 with 86,000 miles. Seems to run strong.

6/60 Powertrain warranty. Turbos are allegedly good for 150k. In the big scheme of engine repairs, I thing a turbo swap is relatively inexpensive.

Seems everything has a Turbo now in North America!
Turbo has been a staple on pickups for decades in europe

Nothing like hurtling through space on a 3 ton Barcalounger with twin turbskies.

Picked up a 2017 with the 2.7L Eco with 71,000 miles. I am worried about the carbon build issues I've seen on YouTube. Anyone had to clean the intake valves of carbon buildup?

Also curious, if a turbo goes out, does it have to be replaced? I'm not a speed demon. I drive like a grandpa, lol.

Thanks

2018+ have port injection with DI, virtually eliminates the carbon build up issue. Since you have a 2017, you are susceptible to carbon build up issues.

Make sure you use a motor oil with Ford’s specification. Carbon on intake valves come from oil vapor vented out the crankcase. Gasoline wets the intake with port injection. Detergents in the gasoline keep things clean. You do not have port injection so the choice of oil is especially important. High priced oil is no assurance of suitability for application.

Yes. The turbochargers are used continuously no matter you don’t run up high boost.

these EB engines would be complete and total dogs without boost, definitely would require replacement.


as for turbo failures - it just seems to be hit or miss across the board. We've run all kinds of brand name class 8 trucks with different brands of turbos, you'll have twin trucks with identical maintenance procedures and one might lose a turbo under 100k miles and the other might go 300k+ before it has an issue.

My 2017 has 170K miles on it. It has been a great engine up until recently. I had a PO1016 and PO0304 code show up and after a LOT of troubleshooting came down to a loss of compression pressure in the #4 cylinder. Valves are good and holding pressure without leaks. It seems to be a ring issue on that cylinder. It holds pressure if I pre-lube the cylinder with oil. I'm not sure what I'm going to do to correct this yet. I hate to think that 170K is the top on this engine. It's been such a great truck up until now. Has anyone else run into this?

Turbos have never had a problem. As I mentioned, the intakes carbon up. Seafoam doesn't clean them out. I saw a great video on doing a walnut shell blasting to clean them out.

Bought an 18’ STX with the 2.7 in 21’ with 19k miles. Now have 47k, and it’s been mostly problem free.

It’s a fantastic powertrain, but I still think it’s yet to be seen with the 2.7, as far as 10-15 year longevity is concerned. What worries me is the dizzying amount of sensors that are on this motor. Everywhere I look, it’s wires and plugs connected to the intake-tract, wires and plugs connected to the manifold, wires connected to the turbo, wires connected to the manifold , ughhhhh. Freaking wires/plugs everywhere. I understand their necessity—to an extent—but in my mind, it’s just one more thing to go wrong.

Mine also seems to slowly consume coolant, but that seems to be a theme with turbocharged engines—in my experience anyway. It just goes…..somewhere🤔

What is also interesting, is the fact that you definitely feel more power when you use 93 octane, with stock ECU. It’s noticeable, and using 87!makes it feel like a turd in hot weather

I had a CEL for something O2 sensor related, but it went away. Idk

coolant definitely has places to leak where it can be burned off before it hits the ground, sometimes gotta do some detective work from top and bottom to look for a trail.

the stock ECU is impressive anymore - the use of wideband O2 sensors and good knock detection lets it make a lot of changes even on stock programming.

ecoboost trucks in general seem to throw catalyst efficiency below threshold codes for no good reason. A friend has the 2.7 and kept throwing it, an updated sensor cured that. My 3.5 will throw it left and right for days or weeks on the driver side bank, then won't throw it again for 6-8 months (replaced the sensor and no change, gas milage hasn't changed, power is good, logging temps and sensor response everything seems fine).

Is 465,000 miles enough to ease your mind? https://www.f150forum.com/f118/465-0...-2-7-a-389552/

that’s impressive…….that being said, I wanna see one with that kind of mileage, but 20 years old. (Yea, I realize we’ll have to wait until 2035 before the oldest 2.7 is 20)

any modern motor that is brand new could prob go 1,000,000 miles in a few years, with only needing maintenance/oil changes. All ancillary parts attached to the motor are all new, and won’t lead to a cascading-type motor failure because it’s new. I love seeing these high-mileage cases, but I’m less impressed if the vehicle is less-than 5 years old.

Well, the truck that is used for doing deliveries has the easiest life of all pickup motors.

It spends 95% of it's miles in high gear / low rpm's. It probably has made less revolutions than a city truck at 25,000 miles.

It spends 95% of it's time at full operating temperature with the cold start ratio being very low.

IMO the verdict is still out on the 2.7 because there ae people on here who have had very expensive repairs done to them.

Remember, it's not a cast iron 390 cu in FE motor - it's a 166 ci 6-banger :)

465,000 miles divided by 25,000 is 18.6. So the city truck has to run 18.6 times faster than possible 1500 RPM to have tuned the same revolutions. Average 27,900 RPM.

Math Is Hard!
