Run a small sheet metal or plastic screw in it if U wish to plug it, then U can open it occasionally to drain it.

If you blow an engine or something major I'm sure they'll go over it with a fine tooth comb. I'm sure Ford is already aware of people doing this. All I'm saying is do it at your own risk.

The only voided warranty would be the part warranty on the cac. It is what $250? It would not affect the power train warranty.

What the heck - where is that gunk going if you DON'T drill a hole? this seems absurd.

(edit: the GUNK seems absurd, not the idea of drilling!)

This is the 2nd time some suggested this. Plugging it completely defeats the purpose of having it and has no advantage.

Thanks for that video... I have looked my CAC 2 weeks ago... some stuff in it, maybe 1oz. Here's my thread:
https://www.f150forum.com/f70/water-...emoval-248485/

I have not drill an hole yet, and when I look at all this yellow stuff, it really proove it is effective.

I also noticed on my Aug-2013 built there is gutter almost at the drill spot and that gutter seems to go below engine... probably for A/C.

I have not seens this on others pics or vids on the forum.

I will try to figure out if I can use this gutter just under the drill hole so that would look even more "factory"... I just have to wait for warmer climate, it's winter here too and -15C right now :p

Look at what comes out, through, the PCV of ALL engines so equipped, re-cycled back into the engine. Most cars have the PCV output vented directly to the intake manifold, downstream of the throttle wherein there is almost aways a vacuum as long as the engine is running.

BUT...

With a FI, Forced Induction, engine the intake manifold downstream of the throttle plate is often under POSITIVE pressure relative to the atmosphere..at EXACTLY those times the crankcase evacuation is most required, WOT, HIGH effective compression ratios = "high" blow-by.

So Ford, along with many other FI engine manufacturers, resorted to an old standy, a modified roadway draft tube.

Basically a tube with the opening at right angles to the vehicle's forward motion "windflow".....the airflow over the opening provides a "draft" effect, sucking the crankcase vapors out and into the atmosphere.

You cna readily see why this type of PCV system was abandoned years ago.

But...why not use the draft tube concept at the inlet airstream just downsream of the intake air filter??

The airflow into the intake, low or HIGH would create a draft effect right at the PCV outflow opening.

No complaints from the EPA..

Unless there is a low section of the intake system wherein moisture, condensate dripping down the discharge side of the CAC, might pool during times when the CAC outlet end cap is at atmospheric pressure, low to moderate intake airflow.
