It is largely dependent upon the relative humidity AND ethanol content. Drier climates will gather less gunk that is by volume water, oil, and gasoline. This stuff is also to a large degree what breaks down your crankcase oil by accumulation.

I cleaned my intake valves, then I installed the Full-Race catch can, and I still had the PCV on the passenger side, it was not gutted yet, in the picture that was 4 days of running here in michigan, smells like gas, I was really surprised to see that much already, so I went a head and gutted the PCV valve and I will check in 5 days and see what it has collected, which imagine will be way more since the can will be catching both sides all the time.

The catch can doesn't catch condensate, does it? It seems the title of the thread is misleading since I thought the only thing to catch condensate is really the hole many install in the intercooler.

jeremyha

the drilled hole in the intercooler is for when the hot air from the turbos get cooled by the intercooler, that causes the air to condense ,and create the moist/water you see in the Intercooler, there is still water/gas in the oil vapors that come out of the crankcase, but this is how I perceive it, but after I saw what my intake valves looked like at 70000 miles I`m glad the catch can is on my truck now, my intake sensor in the top of the in take was coated with oil and the whole inside of the intake was too.

Avaya

Thanks. Sounds like you have to have both the catch can system AND the drain hole in the intercooler.

Yes, that`s how mine is, but I never had issue with my stalling or acting up, but after I saw my intake valves, I knew I had to get a catch can on it, to re-route the oil vapor from the the intake.

Water, oil, and gas respectively by volume. I have a double catch can arrangement in series in my Ecoboost, and the first can catches by far the highest volume of all liquids, and almost all of the oil, which is over a liter so far, and the second can just catches the velocity splash from the first can...only light liquids of water and gas and in very small volumes. I had plugged the CAC hole with a screw and ran it for several weeks that way during which I gathered a significant amount of liquid in the catch cans, but when I checked the CAC for fluids, it was totally dry, which is why I am convinced that the catch can is the most important part of the Ecoboost gunk problem that cokes up the intake valves on cylinders 2&3 through the PCV.
It's interesting that this forum tries to separate the two solutions when they are dealing with the same problem calling it a pissing contest...ya gotta wonder what (or IF) some people are thinkin!!

Only in the form of blow by on the other side of the ignition cycle through the PCV ...The volume is highly dependent upon driving conditions, weather, especially relative humidity. But by volume, the catch can in my truck greatly exceeds the amount of water and gunk than the intercooler produces, but I also have both.

Over the past 2 years I have drained about 2 gallons of that nasty crap from mine and I am relieved it never made it into the engine. My experience is nearish high 30's to high 40's degrees and humidity/rain/fog are the worst time frames with steady 65 to 75 mph time frames of long drives +150 miles.

A large well designed can will catch all distillates, water, oil, acids etc. none of them are good for the motor because they are mixed together and only settle out when the can sets for some hours. Usually draining the can is after a warm up drive so you get this creamy gunky mess of nastiness in a bowl while wearing protective gloves. U see all this mess mixes together when hot into a fluid state of nasty.

If you have a can that only shows you dark colored oil you simply don't own a good design and it isn't large enough.

Is what 150 miles of running in the rain looks like drained hot. Some fresh water dripped out first then this that will settle into 3 distinct groups over a few days.
