About those "catch cans"
#41
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.

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

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

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.

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:

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?
