Not my picture. But every RZR that I have seen has a lot of moisture/condensation coming out of the crank case vent. The dry sump XP900s were notorious for creating a "milky" layer on top of the oil reservoir. Milky or not, even if what comes out of the catch can is mostly just oil residue, it's still bad especially for the turbo models as it coats the inside of the charge tubes and the intercooler and gums up.And why do you have water in your oil?

do you know what "Inlet" & "Outlet" fitting size is required for a 2017 turbo?My neighbors company make them for cars he gave me one to try on my RZR. Once it's installed I'll post some pictures. Here's a link to his very well made.
My last couple of turbo charged cars all ran oil catch cans. Most of the forums for turbo charged cars have tons of threads on this topic. I figured it would be a matter of time before they started up here. You can run a catch can on pretty much any type of car but it is even more important on turbo-ed cars. The amount of blow by when running a turbo is increased because of the added intake pressures. Like stated above the gases are vented from the crankcase normally through the PCV valve and routed back to the intake. In theory these gases are to be burnt in the combustion. What happens overtime is the intake valve starts to build up with carbon which cause the valves not to seat correctly. Also overtime the gas/oil/moisture (sludge) will build up in the inter-cooler and intake plumbing. This will cause the inter-cooler to become less effective at cooling the intake air.
There are two types of catch cans available. Vented and non-vented. The vented like picture by the op will filter the heavy liquids out and discharge any remaining air/fine gases through the vent. The non-filtered type will filter the heavy liquids out and discharge the air/fine gases back to the intake. There are pro's and con's of each. Catch cans tend to be more effective when mounted lower on the machine (Below the PCV valve)
There are tons of different catch cans available. I would avoid some of the ebay junk. Some cans have integrated filters and others require the use of filter media. Normally filter media is like a very course stainless scrub pad. (Don't use steel wool) The filter media will help stop the airborne particles and force them to fall in the can. The link above for the radium can is one of the best cans in my opinion available. It comes at a price. Mishimoto and Addw1 are a couple others that pop in my head.
And finally......Cold climates can also play a factor in the amount of blow by gases that are exhausted by the crankcase. Living in Wisconsin we have warm summers and cold winters. During the summer I would empty the can once per month and maybe empty 2 or 3 ounces from the can. During the winter I would have to empty the can once per week. It is amazing how much more moisture there is when it gets colder. There have been cases where these cans have froze solid and blocked the path of crankcase gases. If the crankcase gases get trapped the pressure will find another way to escape the crankcase. Its usually the crankshaft seal which is a costly repair. Moral of the story......Make sure you EMPTY the can OFTEN. It's hard to believe a mixture of gas/oil/water can freeze but it will.
Just my 2 cents from what I've learned over the years. Hell I haven't even looked at my new RZR to see how the PCV hoses are ran so don't yell at me if I stated something wrong.
