Oil Separator

[Jason Snokhous]

Well...It's not a "claimed" better system it's just simple fact. Especially in a turbocharged vehicle you need a dual valve...not a dual catch can but a dual valve. You need to seriously do some research. It amazes me how ignorant people are on the subject given how much information there is out there. I am not meaning to poke at you just unscoring that I'm not giving you an opinion but rather regurgitating facts from reputable sources and the facts of how physics work from a pressure/ventilation standpoint. Under boost especially you need to create more vacuum than is possible with a single valve system. People that don't understand the difference between a single valve and dual valve catch can system should do some research and educate themselves. It really is quite interesting and you can only gain from the knowledge.

These boards are so full of half truths, mis informed opinions and straight up gossip that it's sometimes hard to make your way through it.

Here's a starting point

So what do you have in your raptor?

I'm not a brand snob mind ya. There are a couple of good ones on the market... but I went with:
(UPR)UPR 17-19 F150 ECOBOOST PLUG N PLAY DUAL VALVE CATCH CAN PRO-SERIESÏ¿½

I'm having a hard time understanding this. If the PCV system is sending crud back into your intake, it's going to pass through the catch can. What is the point of a dual valve?

Just delete the PCV system & install breathers & you don’t have to worry about blow-by at all. [emoji57] Works great on high boost applications, just make sure you are ready to clean you engine bay every few weeks.. oh & it won’t pass emissions testing. lol.

From the little I have read, it seems like dual valve setups just suck stuff out of your crank case that never would have made it to your intake in the first place. I don't get it, unless it's just marketing hype to increase the price of the system.

The duel valve lets the can separate oil out while under boost, not just vacuum conditions.
That's the set up you want.
Whether it has a clean /drivers side separator is a different topic

I'm not trying to pick a fight, I just honestly don't understand. If the PCV is not pushing crap into your intake (due to lack of vacuum under throttle/boost), then why do you need a catch can system that relies on intake venturi vacuum to promote this process? What are you achieving? Again, on a single valve setup, you are going to catch any oil vapor that the PCV system would normally be pushing into your intake. I don't see why a dual valve system is necessary. If anyone truly understands this and could explain it, I'd love to know.

With dual "out" ports or valves in conjunction with check valves (to prevent any backflow through the PCV system and the Catch Can itself) the first "in" valve will use the intake manifold vacuum for evacuation suction when at idle. The second "out" valve will tap into the area in front of the throttle body for the suction needed to continue evacuation when accelerating or going WOT (wide open throttle).

Feel free to post a pic of the system installed!

I don't have time to remove CIA snorkel at the moment, if anyone wants a better picture of the can mount let me know. Good quality components, hoses and fitting are correct type and length.
