Ecoboost Rx Dual Valve Catch Can Install - No Drilling

Just wanted to give you a bit of info on the install and not use a breather on the system as it is very important to have a closed loop system. The main reason UPR decided not to drill the passenger side pipe was because Ford has been and will be voiding warranties for any holes or drilling in the factory intake and turbo pipes.
Most importantly is we had a Ford mechanic see a change in the characteristics of the vehicles running and idling overall and went to our closed loop system. I'm glad you did not drill anything so everything is totally reversible.
But it would be wise to install a clean side separator and get the hoses needed to accommodate the install. You will soon see this is the way to fly and I'm glad you've been following our work.
If you need any help feel free to PM me.

If I install my clean side separator, I'll be tapping the stock air box for filtered fresh air and just buy a replacement from Tasca for $45.

The UPR Clean Side Separator gets as much clean air as it needs from the turbo inlet like factory and runs to the catch can where there is a check valve 5 inches off the UPR dual Valve Catch Can. I am not as concerned about the un-metered as I am about maintaining the proper vacuum in the engine for maximum ring seal and overall performance.
The truck will make more power and run cleaner with a fixed vacuum level than it will with a breather and it does equate to MPG as well as general driving. I just went through this with the Ford Tech and the differences he experienced with running it both ways.
Just giving you some input based on what a Ford Tech found to benefit his vehicle after extensive testing over the past few months.

I believe the big can helps hold the vacuum on the crankcase longer. I have noticed a more evening out of the fuel mileage in an upward track. Fuel mileage used to go all over the place between 2 or 3 miles per gallon per tank, now it is a perty steady figure only varying 1 or 2 tenths per gallon per tank full while driving the same drive the same speed with the same varying winds.

If you go to .net and under his vendor forum he has pictures.

Yes, he is scavenging vacuum needed under boost for proper evacuation to supply the fresh side which reduces the effectiveness of the catch can, particularly since we are only tapping the one vacuum source. And, I don't agree with the whole breather filter explanation. A closed system is mandated by the EPA so that all escaping vapors supposedly get reingested and burned up in the combustion process rather than possibly escaping into the atmosphere. Any set up is going to pull in what air it needs. The only reason for not pulling it in through a set up utilizing the breather filter would be if the air intake has to be monitored for proper air/fuel mixture by the MAF. Pulling in fresh air through the breather filter would not be metered and would upset the air/fuel mixture. But, the Eco uses a MAP where air/fuel is calculated, not metered, so pulling unmetered air in does not have the same negative effects. My truck is idling as smooth as glass with the breather filter installed. The key here is providing constant vacuum, and only utilizing the driver side inlet for vacuum was my biggest concern in whether or not it would be enough. The last thing I want to do is scavenge off this vacuum source and further reduce the amount of vacuum pulling through the can when under boost. Like I said earlier, if I install a separator on the clean side, I'll tap the filtered side of the air box for this source rather than scavenge off the inlet vacuum source.

The EB system doesn't use MAF so it is a mute subject of the fresh air going from the valve cover to the can and into the turbo driver side air intake. It pulls the blow by from the engine thru the can under boost thus holding suction longer.

Not exactly sure I understand what you are asking. Are you saying T into the vacuum line running from the driver side turbo inlet barb to the clean side to provide fresh air? If so, I'd say no since I want that line to provide vacuum, the opposite flow for providing fresh air. I don't know how much vacuum I'm drawing off just one side. I am going to drain it at 500 miles to see what I'm catching. It's only been about 250 so far. Unfortunately, I really don't have any way to compare to the standard Rx install to see how this set up compares.
To me, there's only three options to get fresh air into the clean side. Don't cap off the clean side and run it straight to the filtered side of the air box (but I think you run the risk of getting oil into your air box based on the amount of oil residue I had from blow back through the clean side with the stock setup), cap off the clean side and install the clean side separator tapping into the filtered side of the air box (this would be emissions compliant since everything would be sealed), or do what I did and just use the breather oil filler cap (the only way to get filtered fresh air without tapping into the airbox).
I'm anxious to see this new setup UPR has promised for the Ecoboost to provide vacuum and fresh air without drilling anything, but I haven't seen any of their new install videos they have promised yet.

500 mile check, decided to drill.
Well, after about 500 miles, I decided to scrap the breather filter and install the Rx clean side separator I had purchased. I was seeing a little bit of oil misting from the breather filter. It wasn't dripping or anything, but I'm kind of OCD when it comes to this kind of stuff. The truck had been idling and running fine, and I saw about a 7/10 mile increase in my mpg's on the tank I ran through (I know one tank is subjective, but my mpg's have been pretty consistent on my 87 p/t tune). I installed the Rx clean side separator per the Rx install instructions, tapping into the filtered side of the stock air intake box as the fresh air source. I did go ahead and order a new stock air intake box (top only) from Tasca for about $45 shipped so I can still return to stock very easily.
In the 500 or so miles, I caught about one ounce of a thin brown liquid with a very pungent odor. It did smell of gas. I also noticed what appeared to be a slight drop in the level on the oil dip stick (as carefully as I could guage - as we all know that story). The dip stick definitely did not reak of gas as much as it had been before. I had been watching this pretty closely as I had started to see the level increase slightly and it was smelling more and more of gas.
I guess I was expecting to catch a little more than what I did, but it has been extremely hot here over the last couple weeks. I'm wondering if drawing vacuum off the driver side only is enough. I will continue to monitor it and see if I catch any more once the weather cools off a little bit. Based on the small amount I caught and the misting I was seeing from the breather filter, it makes me think the crankcase is pressurizing more under boost than what the vacuum from only the driver side can draw out. I just don't want to have to drill the passenger side for additional vacuum. It also makes me believe that T-ing off the driver side to provide the clean air source as some have suggested isn't the best way to go as this is only reducing the amount of vacuum. I was seeing a lot of blow back through the clean side into the driver side turbo inlet with the stock PCV set up. Hell, who knows, it may just be better to run two cans and use a clean side separator as the fresh air source.

RX does recommend using both sides. The man has a video on U tube showing the ease of placement of the passenger side. Doing it their way insures suction during all phases of boost. Dont expect any other way to work well. You have proof of catching nasties. But not all. Maybe 1/3. He installs a tee 4 the 2.
