Then, when an owner is driving along and suddenly accelerate full throttle, and boost spools up suddenly some of this is pushed into the intake manifold, and further into the combustion chamber where it causes spark blow-out misfire/shudder. If enough is pushed in the piston cannot compress this and hydro lock occurs and the piston will break, rods bend, and exit through the block (the reason for the NTSM investigation).

The argument that this is just from the water in the air entering the CAC has no fact as there are millions of turbos out there with huge intercoolers and not a drop of water in them, and as you can see, there is far more than water in the CAC, it is water, unburnt fuel, oil, sulfuric acid, etc. and that does not come from the air alone.

We sent in a fresh drain from our shop f1450 ecoboost to blackstone last week, so we will post the results when we get them back.

These are the good questions we want to see, and not the hate and disruption from some that dont tear these down constantly and diagnose the issues and rebuild/repair them.

I will sub to this one so long as it does not turn into a pissing match. Now that dyno sheets and other pictures are shown I will be interested in how this would effect the engine.

The TRUE cause of the shudder/misfire is water from the air condensing in the intercooler and pooling.

If you want to skip to the cause, read Pg 13-15 from that PDF.

Our goal is to keep this good Q&A and no drama. I plead for no drama. What I also want those that think this is the same as buying wheel locks or some LED lights for under the running boards, this is not that type of product. We manufacture 27 different products and feature them to buy or now.......this is a serious issue that effects every modern car and light truck made today and addresses far more serious issues 99.9% are not aware of. That is why all the education and industry references. And the EB has a unique issue with the wrong design of PCV system implemented (I am sure it saved $ millions in production costs, but sure is a headache for those having these issues) and don't mistake my sharing this with a sales pitch. If it was, I surely would not be endorsing direct competitors that do all they can to ride my technical sharing with all for their sales. You can see I mentioned all the other companies that have a true solution that works, and it takes alot of self control to mention and endorse some that have treated me like crap.

Keep the questions coming, and be specific and make sure your all clear on any part you may not understand.

Sorry I missed this post...old dog is correct. If it is a MAF (Mass airflow sensor) equipped engine (instead of MAP (manifold absolute pressure) alone speed density system, that air entering a breather is eventually drawn into the intake manifold and into the combustion process and will throw off the short term fuel trims. A MAF system the ECU/PCM uses data from the MAF, MAP, and upstream O2 sensors to determine cylinder fill rate and command the injectors in the correct amount of fuel to deliver. If x amount of incoming air is measured, and the MAp and O2's provide data that does not fit into the acceptable parameters of what the ECU/PCM is expecting, it quickly tries to adapt to try and maintain stoiometric (target A/F ratio) and quickly adds and subtracts fuel......in short, your fuel trims go crazy trying to adapt.

All air entering the crankcase on a MAF type system must be metered.

Just be aware that most of those pictures are from a GM V6 and not the 3.5 Ecoboost.

The dyno run is from an Audi which is known to be a carbon producing machine.

You do have to read carefully do learn which is which though.

I am asking you to PLEASE not turn this into a drama mud sling aagin....your in the other threads posting this and it is absolutely false findings.

If this was true, all turbo engines would cause this. The water is not released in any sort of quantity until it is subject to the intense heat and pressure of the combustion process. If it is as you believe, and the report concluded (given the misinformation provided the HTSB) then there would not be such high amounts of oil, unburnt fuel, sulfuric acid, and the other compounds that make up this gunk accumulating in the CAC, and every other turbo car & truck (10's of millions) would experience the same. And we would see far more accumulating in the wet, humid summer rainy season here in FL (daily rainstorms, 780-90% plus humidity, etc.)

Please don't do this to this thread computer guy.....lets keep it with actual Automotive Engineers. This is not water from the air just entering the CAC:

I am pleading with you to not wreck another thread.

I'm sorry, can't help myself. I hope it's a typo and your not in some underwater base. lol. It's been a long day at work and reading through some of these threads. Had to break the monotony.

It is what FORD DEMONSTRATED to the FEDERAL GOVERNMENT is the cause of the shudder, I'll take their word for it cause I don't think Ford would purposefully cover up something this serious.

Just posting all the facts out there for people to make up their minds. That is all.

phantomblackgto

Funny thing that Ford has since reversed the so called fix that this investigation used to dismiss the case. Driver control was also identified to not be impaired. I bet they would have thought differently if it had been them in the truck when you pulled out to pass on a two lane road and your truck goes into limp mode. Do you really trust in big company/big government to tell you the truth? I know I don't.

Anyway, even if you don't believe in the dirty side issues, pull the clean side off the driver side turbo inlet barb. There will be oil there. And where do you think it goes after entering the turbo inlet? Do you really think this is a proper design?
