I have never had gas in the oil. Also, your statement that all or most will be affected by a timing chain stretch and/or cam phaser issue is misleading and reckless.

Your hatred for the EB motors is well known. It has also been determined that consistently shorter oil change intervals does prolong the timing chain and cam phasers.

 

But but.... the Internet forums say everyone is having a problem... The Ecoboost has been out for 6-7 years now, but it's only been a problem for 2-3 years. What changed? People started racking up 100±k miles?

 

I've seen enough high mileage EcoBoost trucks with nary an issue to believe that. Also the millions of other 3.5L and 3.7L non-turbo engines that use the exact same timing set and phasers. Not saying it can't or won't happen to my truck, but to say it's almost a sure thing just seems silly to me without more condemning evidence.

 

Don't forget the high pressure fuel pump driven off of one of the cams. That's an extra load that p.i. engines don't have.

 

You folks realize that the problem is significant enough to where Ford issued a TSB for this, right? Ford also redesigned the cam phasers for mid 2016 release.

 

Ford EcoBoost Engines Reach the 5-Million Mark ? News ? Car and Driver | Car and Driver Blog

This is an old article and as of this printing, over 5 million ecoboost engines of all sizes have been sold. As of Nov. 2015, Ford has sold it's 1 millionth ecoboost F-150 with sales percentages reaching 63% of all F-150 manufactured. That's 63 out of every 100 trucks have an ecoboost. And as Tom has mentioned till he's blue in the face, the N/A 3.5L and 3.7L siblings share the same timing equipment with no remarkable issues. These engines combined have made their way into the Taurus family, Mustangs, F-150 and Transit vans. Millions of these engines on the road.

Someone tell me why my 70K mile ecoboost is just as quiet at cold start as it is at night when I shut down. Am I the lucky one in a million? I have three other neighbors with aging ecoboost trucks like mine with out issue, are they just lucky too?

 

All depends on how clean the oil passages are leading to the cam phasers.

 

This is the thing that the EcoBoost loyalists don't want to understand.

The EcoBoost family of engines, not just the 3.5, but the entire family of engines has had rampant problems, hence the multiple TSBs and even revisions to existing TSBs that are still coming from Ford on them to this day.

Part of it is poor engineering, part of it is lack of sufficient real world testing, and part of it is just the laws of science. A more complicated, sophisticated engine is naturally going to have more problems, because there are simply more points where problems can occur.

My brother has a '13 EcoBoost with half the mileage than my Coyote has, and twice in the past month his truck has been in the shop and/or stranded him for two separate issues.

The dealership where I bought my truck sells a TON of slightly used F-150s, and they tell me that they commonly have issues with the EcoBoost models and have had problems diagnosing the issues sometimes before trying to sell them.

But back to the cam phasers.. for the 5.4 some guys install a kit that effectively locks the phasers and prevents a lot of the problems. At first I wondered if something like this would help the EcoBust...but honestly I think it's a different source of the problem for the new engines and this patch wouldn't apply.

 

It wouldn't matter to some people if only 3 EcoBoost trucks had issues. They're new, different(in the truck world at least) and utilize more technology. So obviously they're junk and also pure evil.

I think the fact that with a good boost launch they'll outrun any of the V8 trucks helps fuel the hate.

 

It is by no means anything to do with "who is faster". Nobody argues that. However, the serious design flaws in the 3.5 ecoboost are undeniable. This will go down as probably a worse engine than the 6.0 PSD.

 

The 3.5 has a long ways to go before it can even be put in the same class of bad as the 5.4 3v(entire timing system and spark plug issues)or GM's 5.3(complete engine replacement due to oil loss through AFM system, porous head castings putting coolant in oil and early gen piston slap issues).

SOME 3.5's have serious timing component issues compared to MOST 5.4 3v's. Early models had condensation issues that caused misfires. That has now been dealt with.

The 5.0 has had issues with timing components as well and even has a tsb out for it. There was also an issue with a knock due to cylinders being oblong.

Sounds like they're all junk! Better have a horse or donkey as a back up just to be safe!

 

What I've highlighted is what becomes insulting. In my case it isn't matter of loyalty. I didn't choose the engine, I chose the truck which happened to be the best deal on the lot and it happened to have the engine. I had spec'd out a 5.0L truck and I'm actually very happy that I didn't go with that one in light of the chronic issues that have come from that engine.

Given the price of the 2015+ F-150's why are they still selling like hotcakes if the EB engines are so plagued with issues? By now, Ford is selling new ecoboost trucks to the same people several times over. Are they gluttons for punishment?

IDK guys but I think the internet has a way of blowing something way out of control.

"My brother's cousin's sister's husband's nephew bought an ecoboost truck and it failed".

 

It's gonna be pretty hard to take you seriously. Fairly certain you suffer from lack of perspective. The EcoBoost engine has been out since the 2011 MY, it's now five years later. Take a gander at the 6.0L forum circa 2008 when that engine had been out for that long:

6.0L Power Stroke Diesel - Page 1551 - Ford Truck Enthusiasts Forums

Now go along any internet forum of your choice, FTE and others, and count how many EcoBoost-related problems you can find in the first couple pages. Note the severity of the problems...is the issue a minor misfire that can be taken care of with new plugs? Or is it a $4,000+ head gasket job due to a known weak design?

Compare all of these things with what you see on just one page of the 6.0L forum. If you come back here and say with a straight face that the EcoBoost is anywhere in the same realm, I doubt you'll be taken seriously on here again.

 

How likely is a dealership to change out phasers based on the tick only ? I don't have any check engine codes or the cold startup rattle, just the tick that sounds like every video online of cam phasers ticking. I'm still under power train warranty. It's in the shop now for tomorrow.

 

" 63% of all F-150s sold have a V6."

Lol.

That's because there's ONE V8 option, and multiple V6s. So, from the math we know that the V8 is still the best selling single engine option, and that is why GM has wisely stuck their R&D money into that tried and true platform with great success, outselling Ford monthly now.
