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.

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.

Mine smelled a lot like gas. How long have you had yours installed? Have you checked your IM line? Mine did have some oil residue in it. It wasn't dripping or anything, but definitely some oil residue was present.

I haven't been able to recognize the odor from mine, defiantly different smell. Think RX is getting it tested.

I have about 1500km on mine so far. Haven't checked it yet, probably should

Factory connectors
phantomblackgto,
Where did you get your OEM connectors from?
I just finished my dual valve Rx CC install for my 2014 F-150 Eco. I installed mine the same way you did by only using the OEM port on the diver side turbo inlet for evac during boost. I order a cleanside sep. but it did not arrive yet. So for the interim period, I connected to the air box and then tied into the original port on the diver side valve cover. Once my clean side sep arrives I will simply connect to it and cap off the valve cover inlet port.
I'm heading to the shore this weekend (+300 miles) and I'll check the catch can upon my return. Anxious to see what I will be keeping out of my engine? I also share the same concern you mentioned; is the CC working as intended with only one source of vacuum during boost?? Hopefully it will, but if not I may be inclined to hook up the other turbo inlet. I want to catch as much of this stuff as possible.

I will tell you it is a real sumbitche to get the 1/2" rubber PCV hose all the way onto the connectors. That was by far the hardest part if the entire install. You can see I ended up sealing them up with some black RTV which seems to be working fine. The other option might be to use 5/8" line on the connectors and then a 5/8" to 1/2" reducer for connecting to the supplied 1/2" hose.
One other thought on your current install, you might keep checking your air box to make sure you aren't getting oil blow back through that line. I was getting quite a bit back through the turbo inlet with the stock set up. I had considered doing the same thing as you until I got my clean side separator, but decided to try the breather filter instead to (1) avoid drilling the air box to see if that was an option and (2) because I was worried about oil blowing back through the line into my air box based on what I was seeing in the turbo inlet.
As far as only using the one side for vacuum, UPR's new Ecoboost setup is only using the one side, AND they are tapping this line for the fresh air source, so they would have less vacuum than the way we are running. I asked Tracy about this and he said it wouldn't hurt to try it, but he still recommends tapping both for the best vacuum.
