I still have not seen anyone argue that anything but water is coming from the air intake. This is a straw man argument and I can't help but feel as though you are using it to keep promoting the rx system that you designed. No proponent of the weep hole has argued that your system is a bad idea, just that there are 2 phenomenons going on here. A significant amount of theory and data support each one. We get it. This thread is about the weep hole.

So look at Ford's patents on a PCV system that works under boost and educate us as to why that does not apply to the Ecoboost. I've posted the US patent # (US20100300413 A1) as well as a link.

Ford has patents on this stuff and they were introduced in the Ecoboost family of engines. Matter of fact Ford has plenty of patents on the EB engines.

You conveniently duck the issue and claim these systems are not properly functioning. Common sense states the system would not work like you say (not evacuate under boost) or, like your PCV 101 (yes I did watch it) video states, we'd be blowing seals left and right.

That's nice. I can claim whatever I want too, this is the Internet. I can even post pics of race cars and such too. I also know a hard sell when I see it.

Sure, under short trips in the cold this will accumulate. Since the EB has been around since 2009 why are we just hearing about it this year? Hint - the US and Canada has had a winter shattering many records for cold and snow throughout both countries.

You also ignore the evidence from those that have had the latest PCM Updates installed (for the condensation and fuel issues) that have had the issue disappear.

You also ignore the fact that the car/SUV applications do not experience the condensation issues, despite having the same PCV system. They also accumulate the gunk too. That's because those intercoolers are not as efficient due to the much tighter engine bay. If the source of the issues was the gunk it would be present there too.

A true fix is not a catch can. It's another band aid. If Ford truly has a defective system, have you shared your theories with them? Have you discussed them with the NHTSA (who is investigating this issue)? Have you spoke with Consumer Reports who would love the scoop on the defective Ecoboosts? Surely you want to get to the bottom of this for all Ecoboost owners, even the ones who don't buy a catch can?

Can you even comprehend that the answer to these issues is not a catch can? Can you comprehend that the gunk in the intake and the condensation from the air are not the same thing? And that many owners do not experience their engines making oil?

You just want to say "catch can fixes it all" and pimp that the PCV system is the cause of all the issues. Yet when asked why you post "PCV 101" videos and go on and on about how the system is defective. Then when challenged with facts try to discredit those that disagree saying "I am an Expert". Classic Pitch Man sales 101.

Your continuance of putting down peoples intelligence and name calling is getting a bit old. Grow up and have an adult conversation.

Whatever.

Does a catch can capture junk? Yup.
Is it needed? Nope.
Will your engine run for many miles trouble free without it? Yup.
Does it hurt? Nothing but your wallet.
Will it solve the issue of intake water condensation? Nope.
Will it fix the issue of water condensation causing misses and power loss? Time will tell.

I think you summed up why the catch can does little for the real problem (slugs of water ingested and forcing engine into limp mode). You proved, through your own use of a catch can, that it doesn't pull water out of the system during the times that cause the stumble/limp. Long drives. Those are the times that produce the real moisture problem with the EB.
I think we all agree a catch can reduces crap from being ingested and causing buildup. But it doesn't help much with the water forming in the CAC, which is what really causes driving problems.

Tuner Boost

Not true...all of these using this have posted it eliminated the water in the CAC.....and you DON"T need my system, you can modify a few other cans to do the PCV mod and have similar results. If the proof of these photos and testimonials of those doing this are not enough, you will never agree.

Every one of these people have stated it stopped the water accumulation in the CAC, stopped the oil level raising due to fuel and water ingestion in the crankcase, and stopped the shudder issue.

itguy08

I've been thinking.... And this is a serious request for Tuner or any other lurking auto engineer.

Why don't you contact the mods and see if you can do a writeup with an in-depth walkthrough of the Ecoboost's PCV system from the air in the intake all the way through. You could have it posted as a sticky or a how-to article. That way we all can see what is going on in the system and how it all works together. And it would all be in 1 place for us to reference.

I know you have posted it in various threads but a condensed version would be great for us all. And I'd say don't have it open for comments or discussions.

brucesears

Nobody is disputing that, we just don't want to add even more that comes from the condensation in the crankcase. Besides all the unburned fuel and crap that goes along with it.

natural gasser

along with increased water from the ethanol.

itguy08

Tuner Boost sure seems to say so:

The majority of the water in the CAC is from it condensing.
