Doh! Thanks, I may get some satisfying drainage after all

This is a very long thread.....so, if this question has been answered, I have no idea where it is. LOL. I drilled the hole in my 2014 Eco back in December and a ton of junk came out over the first two days. Now i see a constant film on my air dam (FX4) and a few drips on the ground every morning. My truck runs great and no other known issues. So, is it normal to see constant drips? I know these are dirty engines.

I'm worried by this isolated part of your post. How do you know a ton of junk came out over the first two days?

If the condensate level in your CAC was very high, you might see some drainage immediately after drilling the hole, but most of us haven't seen any expulsion until the motor goes into boost. This can't be done while revving the motor in park. You have to put it in gear, stomp on the brakes, and give the accelerator a few good stabs up to, say, 2.5k RPM. This procedure will squirt out most of the accumlated condensate, leaving very little behind in the CAC. Anything remaining (and any fresh accumulation) will be expelled during normal driving.

Those are the only ways I know of by which you're going to witness a large drainage or expulsion ---- by gravity, immediately after drilling the hole, or by observation with the motor in boost. So unless you hung a GoPro off of your front bumper as you drove around town, you can understand my concern for you saying that you saw a ton of junk come out over the first two days - did you drill into something else?

It seems the PCV systems on the early 3.5EB most likely creates a lot of crap in the CAC under certain circumstances, long runs under 2000 rpm's and PCV poor operation that can be taken care of with a better can install, but the water will occur until the later generation front grill mods . The latest designs have mostly taken care of the condensation and oil mix with it by adding shutters and further changes to the motor. The later designs take into account most normal driving and not the Tow/haul work modes that the earlier design was intended to handle. Thus the tow/haul work modes are easily handled now by the shutters in the front opening up for full CAC capabilities which was the early intent of the truck anyway.

I am going to attest to the fact that if U purchase the sport mode with Tow Haul, The Sport mode, and the regular mode with constant use & U will most likely only notice hesitation in the factory install normal mode. Tow haul and Sport mode kick Arss !

The biggest factor is the charge line is sucking off the bottom of the CAC (intercooler). If Ford had of designed this with the Out going line at the top of the cold side we would have never seen this problem to begin with, even most of the aftermarket coolers still suck off the bottom.

Found this film. AT 27,000 miles on F150, owner decided to put a tiny hole with a tiny screw plug on the lower passenger side tube of the CAC, a tiny amount of oil came out it when the lower tube was removed.


He found no evidence of water oil mixture in the CAC with removal of the CAC from the vehicle.

Man, you were right there, so close, with something truly informative! What came out?

This thread is super long...

U R going to get this, Ford F150 is so ahead is World Class once more with all this Info.

After replacing plugs and coil pack finally decided to give this a try on my father in laws 2013 EcoBoost. Drove it around some back roads giving it hell for about 20 minutes to get all the gunk out and haven't had a stutter unless I get it up top 4000 rpms. Hopefully after some more miles driven that goes away to. Also not only is the stutter gone but mpg went from 15 to 19-20 in town. I definitely recommend. If you have a problem with the dripping then I would recommend putting a small screw in the hole and remove periodically.

A tiny hole and a screw to plug it will save U a lot of time not having to remove the CAC, depending on the year truck you have and which side you need to put the hole/screw in if you so wish. I haven't had one hiccup with my 16 2.7 L. with 65000 miles on it but most likely will drill a hole in the passenger side by fall to see if any oil drips out and then plug it with a childs toy battery cover screw.
