You guys just *have* to see this. He estimates 100,000 miles. The *crank* broke, and there's burned oil everywhere.
2019 Ford F-150 3.5L Ecoboost MAJOR ENGINE FAILURE! Full Teardown W/
- Thread starter bobdoo
- Start date
It did look like a Purolator… Or Motorcraft? Seems like the little EBs are tuned to the gills, putting out a LOT of power for their displacement-not sure that’s a recipe for durability!
One youtube video hardly makes it a rule. There are plenty of high mile Ecoboosts out there. Go over to goodcarbadcar.com and see how many F150s and sold and get back to me.
Oh good, we are way overdue for another Ford bashing thread. 
They should have used something GTL based.

Oh good, we are way overdue for another Ford bashing thread.
In my case it's not a Ford bashing thread, it just gives reinforces my (perhaps ignorant) opinion that turbos are less reliable than a gold old fashion pushrod v8.
Ram is putting an even smaller turbo (3.0) in their new trucks with a lot more power and torque (540 hp and 521 lb/ft of torque). These kinds of videos don't bode well.
We’ve blown up the 3.5 EB F-150s we bought… If they’re so great, why doesn’t Ford put them in the F-250, -350, & -450s?? The YT engine looks pretty neglected-it takes a LOT of abuse to stick all the compression rings like that. Ford isn’t the only one-GM has been stuffing tiny turbo GDI 3 & 4 cylinders in a lot of little SUVs too. Not sure they will fare any better…
Does "we" indicate fleet or corporate use? (Not personal, I hope.)
What approximate percentage of the EBs fail, and at what typical mileage?
Do you know the failure mode? (E.g. head gaskets, timing chains, dropped valves, etc.)
Are there unusual usage patterns that might lead to the failures?
Just idle curiousity on my part.
Also wondering how Ford's 2.7EB and Chevy's 2.7T are holding up in truck service.
Please..................
Just a WAG, but probably whatever bulk oil when they had the oil changed, and probably followed the OLM + some.
Yes! Thank you for the correction.
No way; they leave a lot on the table, as do the 2.7s (which BTW can easily be tuned on E85 to eclipse even the stock 3.5HO)… but let me tell you this: mixing E30 into a 3.5 and having the right tune can easily make well over 500rwhp. I’ve been running that tune for most of the 55k miles I’ve owned my ‘19 STX. Other than about a 2mpg hit (winter is worse, for obvious reasons) there has been no problem whatsoever.
But, as with any complicated engine that has as many electrical/electronic gadgets & adjustments inside the sump like the 3.5 has, neglect will cause expensive failures.
Maybe someday once the kids are out of college, if ICEs aren’t banned by then, I will tear down my 3.5 and build it to challenge the current 1/4 mi F150 record, which is somewhere in the mid-11s IIRC. The Lord knows I’ve paid my penance being away from racing for too long. It will need more than 800rwhp but that’s easily achievable, since the swan song Ford GT tops 800HP on “factory” parts. I’ll be calling Harry Hruska for the turbos and tuning.
Didn’t watch the video. Any engine can come apart if abused by way of repeated full throttle-top of the RPM range blast driving conditions (cold or hot), neglected preventative maintenance, use of bottom shelf products, and ignoring warning lights etc. How was it driven daily? Nobody here knows. This ain’t a Ford thing….
My 2.7 is still low mileage (ford) at ~65k, but it’s one of the best parts of the truck. Only flaw surrounding it is the o-ring seals for turbo cooling lines on the back of the block. The engine so far has been superb for DD, towing, and some spirited use. Note - I run one grade thicker on the oil. Oh, being such a small displacement it can also be idled for a long time while being very thrifty on fuel. Stays in a high gear and loafs around favoring low rpm torque. Mine’s still young, I realize, and is not yet much of a testament to longevity.
Fordtechmakuloco on Youtube works on a lot of these engines. He has replaced more than a few of them.
Regardless of what engine he is disassembling, I just enjoy his videos.
