The Ecoboost thread

I have just slightly less than 110K on mine.

I can't afford to replace it, so
I hope it hangs n as long as I

3-4000 mile oil change intervals help, I think.

On the 2020-up 2.7, they changed it so it runs a wet oil pump belt. It's like a Ducati timing belt, except it is soaked in hot engine oil and as it wears down, the rubber floats around in the oil system. There's a class action going on for the 1.0 3-cyl EcoBoost for its wet oil pump belt. The 2.7/5.0 both use the welt belt, only in the F-150 made after 2020 which is still rather new, but is also found in the 3.0 for 2020-up (same engine as the 2.7), so your Bronco and Ranger Raptors have this as well. That's not to mention the faulty C-D-F drum for the 10R60/10R80 from 2017 and beyond. Ford hasn't fixed this problem permanently and gaslights everyone into thinking it is a software issue. THe Mustang 5.0 still runs a direct drive oil pump.

There are also reports of cam phaser failures on the newer 2.7/3.0 as well. Not as prevalent as the 3.5 Gen I and Gen II but still failures.

The original 2.7 from 2015-2019 and 3.0 from 2017-2019 (and out to 2020 for transverse applications) still use the chain for the oil pump.

Yeah I'm aware of the CDF drum. Same deal as the Ducati aluminum dry clutch basket getting groves from steel plates.

I haven't heard of 2.7s needing cam phasers but you sound like you're in the know so I'll take your word for it.

That's even more evidence that an extended warranty might be a good thing.

Unfortunately no. It's been shown that frequent oil changes do nothing for the mechanical/design defect of the cam phasers. Only solution is to get the revised phasers. Local dealer said a new Raptor back in 2021 had gone back 2-3 times for replacement cam phasers under warranty because they could only replace the bad phasers with new defective phasers. I believe the updated/fixed phasers are now available.

It's not common on the 2.7/3.0 but there were reports of them failing.

One of the high volume Ford techs showed a "Revised" CDF drum which was anodized black. I guess that was Ford's solution in the interim as this was a new replacement part from the supply system. Remains to be seen if this fixes the issue.

My understanding was that it's not just anodized but hard anodized.

Standard anodizing does nothing for surface hardness, it just helps with corrosion.  Hard anodize leaves a 60rc or better surface hardness which would certainly keep the splines from getting grooves.

Time will tell

I'm familiar with hard anodizing. AR15 7075 T6 aluminum receivers are typically Type III hard anodized to RC 60-70 and it still wears through with normal use. Mag well, charging handle contact, cam pin wear, etc... SIG Sauer's answer to that was replaceable steel inserts on the high wear areas like the charging handle latch pocket and cam pin pocket on the MCX Spear.

This still feels like a band aid fix on the 10R60/10R80/10L80 transmissions. It took Ford 8 years to come up with this after how many millions of test miles. The real solution is probably a different drum material but the accountants wanted to save x dollars per transmission. But yeah, only time will tell.
