Reliability study shows EcoBoost 3.5L V6 on top

[tsigwing]

Was not expecting so much tea in here.

TGIF I suppose.

I’d wager the Venn diagram of all the trucks with 150k+ miles with reasonable regular interval oil changes(5k or less), a good maintenance schedule (plugs and things of that nature), and not driven/towed like they are stolen daily is a circle.

Lets’ argue wheelbase length after this blows fog horn signaling all 157s

and some would argue that is not reasonable, but excessive

Then we can compile a list of engines that have grenaded on this forum and discuss how they were all 5.0 V8s. ??‍?‍???

There have been a handful of blown up 3.5s on here. There have also been a handful of blown up 5.0s. I can find some examples of each. More likely your motivated bias gives you a keen eye for V8 failure threads. You just happened to gloss over the other failures because you didn’t want to see them

But what can we derive from this? Unless we can verify how many owners of each are here do we have an accurate ownership representation? 99.9% of owners aren’t on a forum. You really believe there haven’t been any 2.7 failures? The things recalled for failing but I can’t find an example here. Doesn’t mean it’s squeaky clean…the PowerBoost being berated doesn’t mean it’s unreliable….it just means high representation on the forum and more posted issues. I wouldn’t call your PowerBoost unreliable based on a forum metric.

Take a look at the forum views on a given day. Any day. BY FAR, this forum is made up of mostly PowerBoost or 5.0 owners. Both will be the most posted about, and have the most issue posted.

The 2.7 section never has the traffic the PowerBoost or 5.0 sections have. As such, no issues exist in the forums sphere for that engine. Nobodies here to post about it when it has one.

I agree that a ratio correction of engine production numbers, would make this compilation of data more meaningful, so it could be apples to apples, rather than raw data but I think requiring accidents and engine replacements to be accounted for, is a bit nit picky.

Accidents should more or less be uniform across the field, though perhaps engine replacements wouldn't be. Even so, likely a small group, relative to the sample size.

The only reason I bought my 2015 F150 was because of the 2.7L. Never had any issues out of it. Great motor, great gas mileage, tons of power.

I have nothing against the motor I've only driven it in rental trucks. I tow cross country and haul 600 to 700 pounds on weekends. 2.7 just doesn't have enough power for me. Honestly at times I miss the 90 Ft lbs of torque from the 3.5. I purchase what works for me.

I do admire your keen eye for motivational biases and for bikini pics featuring trucks in the background.

You have successfully peeled back the curtain regarding the anecdotal nature this forum and most others I suspect. I enjoy learning about my truck and sharing experiences where I can be helpful. The competitive banter is pure fun. These trucks are great vehicles for the most part regardless of powertrain choice. There’s not a bad one in the lineup.

Edit: That was a bad Ted Lasso ripoff on my part. Apologies.

Are saying the 5.0 is not any more or less reliable than the 3.5?

My '09 4.6 2V takes the crown over all these engines. Too bad it can't get out of its own way.

I had some work trucks with the 4.6 back in the day and can confirm, they ran forever!

A lot of good hypothesizing. I follow a few Ford mechanics who make a lot of $$ doing timing jobs and leak repairs on Gen 1 and more recently Gen 2 3.5s. My take is that people like this engine enough to put $7K into a periodic rebuild. And that the rest of the truck is working well enough to get ROI on that investment.

Reliability is such a hard word without context. When used with a mechanical system, It is really mostly pointless. What makes it reliable? Uptime? Cost of repairs? Number of breakdowns per week? Longest running? With cars lets add, is it going to leave me stranded? Its all up for interpretation.

As for truck engines, My 170k 5.4 never once left me stranded. The phasers rattled, mpg were horrible, was gutless with the 3.55's on it. Changing the sparkplugs made you appreciate the lottery.

Far from a good engine, But never once did the engine leave me stranded.

Now the Fuel pump driver...........by the 3rd tow I just kept one in the truck at all times. LOL!!

Doesn’t say anything about being the original engine. Just trucks that are still going after 150k. I know 2 people with new 6.7 in their 200k mile trucks.

And those could easily be 400K mile engines without the emissions stuff! On the other hand I had three 3.5 Ecoboost trucks and then gave the Coyote a try in my last truck and while the performance was good I couldn’t live without that extra 90 lb/ft of torque at a much lower RPM. Now I would take a Coyote swapped Foxbody any day of the week!

My 2023 work truck with the 2.7 overheated and had to have the heads replaced. happened at about 62k miles. I have no clue what happened. I wasn't dogging it or towing when it happened, it just did.

"Poorly cobbled together" thanks. I wrote it.

Lol, thanks for writing the article. The world would be A LOT different if everyone's work was publicly available for criticism.

To be clear, I have bookmarked 25 posts on this forum for future reference, and I have referred to many of them. Six of my twenty-five bookmarks are posts from @HammaMan. I consider him one of the great contributors on this forum. I don't know him other than this forum, and don't agree with everything he posts here including his well-documented, low opinion of Ford's CEO (I do find his posts concerning the CEO amusing). However, his posts are generally informative, well thought out, researched, and considerate (mostly).

I don't block anyone, regardless of how much I may disagree with or dislike them. To be clear, I do like HammaMan. He's just very direct, and a lot of people take that as mean or rude
