It's been discussed in various threads that a potential solution to the intercooler condensation issue is a catch can. I know that many people have installed a catch can, I wanted to get some before/after observations and results from installing a catch can.

Here it is guys, what more proof do we need that this **** makes it into our intercooler?

Here is a video of me emptying it after 130 miles of sub-zero temperatures.



Here is after it settles (different time but it always settles the same)



Here is what it looks like after it evaporates out:



A closer look:



Here is what the stock charge pipe had in the bottom of it when I upgraded to the AFE Bladerunner:



Here is what someone else had posted that they pulled from their intercooler:


What can we say for certain? What the catch can is catching is the SAME crap in our intercooler.

We can speculate that the catch can is catching some (I would venture to guess most) of this .

I did the catch can mostly to get rid of the water in the oil that accumulates during cold weather. The last 2 winters my oil level has steadily risen throughout the winter. After only about 1.5 hours of running time and emptying the can twice, my oil level is back down where it should be and it looks much better. No milky look.


If it does nothing else, it's worth it just to keep the oil cleaner. Not to mention my valves won't get all coated with the crap it takes out.

I am keeping this out of my air stream.

So I don't get this!

Or this!

That (residue on oil cap) is not unique to the Ecoboost. It's been present on the Modulars (and other engines for years).

This will be my only post to this thread.

You are absolutely correct! The point that you are constantly missing is what happens to the condensation AFTER it occurs!

When it gets hot enough to evaporate, it goes to the same place it goes in every other engine. Right into the intake to be burnt.

Obviously you have learned nothing yet about DI engines!

The picture of the intake valves are mine at 68k. There is no wash as the fuel charge is injected into the combustion chamber below these valves. The only wash that they will get is by the accumulation of snot shown in the first picture!
Accumulate enough of this and you begin to throw off your air/fuel ratio, which which ultimately leads to loss of fuel efficiency and power, which normally would be the best case scenario. The worst case scenario would be severe valve deposits that ultimately lead to valve train failure!
You had better learn it, because turbo charged DI engines seem to be the direction we are headed in the auto industry!
