I put enough into the previous post, but here's something I'd like to see that would help with this discussion:

Everybody: Scope your intake valves on your non dual-injection Ecoboosts and GDI non-Ecoboosts, take pictures, and report back with:

1. A picture of "typical" intake valve
2. Region your vehicle lives in
3. Year
4. Model
5. Odometer
6. When you installed a catch can, if ever, or never
7. Typical use of your vehicle (police, taxi, landscaping, soccer-momming, racing, highway burbling, towing, etc.)

With this info, we could finally have some evidence as to the scope of the problem and either (1) boost the entire catch can industry and retrain Ford motor company as a whole and conclusively make our vehicles last longer or (2) topple the catch-can industry and have Ford pat their engineers on the back and conclusively save some money on useless add-ons or (3) land somewhere in between. Either way, a gathering of evidence like I propose here will save electrons and manpower in the long run as the debate will be lessened quite a bit.

There are countless Ecoboosts out there doing police, taxi, landscaping, soccer-momming, racing, highway burbling, towing, etc. , with little in the way of facts published regarding this potential phenomenon. We can fix that.

GO!

 

DAMN, when will I learn?

The only cleaning procedure is to either remove the intake and clean the back of the valves manually or remove the head(s)

The problem firsts surfaced when attempts were done to perform a normal injector service and the resultant carbon .breakup tore the turbo fan up. The main reason for the buildup other than boosted crankcase pressure is that the valves are not cooled as with port injection. When the crud hits it sticks to the backside of the valves. This was solved partially with DUAL INJECTOR STRATEGY. FORD isn't going to admit it as the warranty claims would go through the roof. And this occurs across all manufacturers, not just FORD.

There are other factors involved but it makes little sense to try and discuss them here. Most people trade before the symptoms show..

The question is, how are EXTENDED WARRANTY COMPANIES going to address it when the time comes?

 

The time is already here. They've been stamping these things out for almost a decade.

 

Extended Warranty Companies are gonna say, “No broken parts here.
Valve cokeing is a design or maintenance issue. Not our problem.”

 

There are lots of Ford F150 sites out there. There are millions of ecoboost's out there, many thousands with some pretty big numbers on their odometers. You'd think, if this crud buildup on the back of intake valves was a thing, somebody would have posted a thread about their problem. One thread. Maybe a picture of one actual F150 ecoboost valve with buildup on it. One.

 

meh for the cost of a cheap one I dont see a reason not to do it if you wanna, emptying it i suppose is the only downside.

 

I doubt a catch can would actually cause any problems. But a non-mod friendly dealer could use it as an excuse to deny certain warranty repairs.

 

I’m with Mr Jones on this one. These have been out long enough that the forums would be flooded with threads full of coked up valves by now. Instead of that, I see sunroof issues, freezing lock issues, APIM issues, etc.....but no valve issues. Nor do I see turbo issues. I only see posts where folks claim there “could” be issues.....but no actual issues.

 

Truth

And it wouldn't surprise me.

All true. If this valve coking was even a very slight problem there would be a new thread about it every single day. I'm on and read a couple of different forums as well and valve coking in the ecoboost engines is just simply not a problem.

Did I mention I have one for sale, cheap... works great! No one should be without one. Hurry before your engine cokes up and quits running!!!

 

That's what I was getting at with:

It would sure be neat to put this subject to rest one way or another. It seems like a topic of conversation way more often than it should be.

 

I don't think there is anything to put to bed, though I do understand what you are saying.
I think the naysayers would argue the sample size was too small compared to the number of vehicles produced.

There will always be random people that say it can happen and that their dad's mother's friend's grandson saw pictures of it on the internet.
But, of the F150 forums I visit regularly, it isn't an issue. And believe me, everything gets discussed....IWE problems, mpg threads, what tire fits, locks, roofs, CAI kits, what color should I get, is this a good price, etc.

Yet, in all those discussions, nobody has shown up with actual valve coke issues. Lots have said it can happen and that we'll all die a fiery death if we don't get a catch can.
I think the truly incredible brilliance of marketing catch cans for the F150 seems to be that what they claim to prevent isn't occurring. So all their customers are going to be very satisfied and think the magic catch can kept their valves from coking.
My hat is off to them,

 

I tend to agree!

Still, if we get some real pictures and information from some volunteers here then we can do good for all mankind at least until this thread's popularity wanes and it drifts into the depths of "Beyond Page 1" .

 

 

Kultulz, we know there is vapor. The presence of the vapor isn’t being questioned. The real question is whether or not it is an issue.
It doesn’t seem to be an issue.

 

Why would it not be an issue? Why did FORD go to dualing injectors?

The fumes are going to do more than just coking intake valves.

Now let me gets this right. I am going out and buy a 40 to 50 thousand dollar truck ... ... and not worry about correct maintenance as I am well off enough to trade up whenever it runs out of drive-train warranty?
