Getting rid of the roll over valve

You know on ATV's a water trap is used. A low point in the intake hose the water and oil will fall into even under boost pressure. Make the trap removable for easy clean up.

Im definitely not talking about creating a new mod, I'm talking about an oem part!!!

Maybe having the hose hang down below the running boards is a bad idea? Being that it was very cold and that combined with the heat coming from the muffler outlet created a mist of moisture that ended up freezing on the end of the hose. If we keep the hose out of the exhaust stream and up above the running boards maybe this won't happen?

Or just put a breather on the oil tank, might have a few around from my car builds.....lol
Or even a PCV system

Not a bad idea but I think the concern is where does all the milky oil crap go?

Yes exactly. What/where should we be inspecting to see if cleanup is needed? Would like to check/clean anytime I put the sled back in the garage from a trip. I'm guessing my tank my be sealed better due to track change by dealer prior to delivery. Leaving stock pluming in place.

As correctly stated earlier there will be no milky crap if the motor is run to operating temp normally. if short run times are frequent yes there will be condensation present.
Pull the oil cap off your car in the winter under the same conditions, you will have the same results........

They don't take off the oil tank during a track exchange. They take the whole cover off chain case and leave the oil tank cover in tact.

Is the rov the cause of dumping water vapor and oil into the intake tract?
It's more than mist, its foamy oil, needed many scott towels to clean it out.
If it is the rov, is there a better one I can use which won't cause this?

Its the stock ROV system that dumps water and oil vapor into the intake tract yes. When the engine is shut down it literally just drains into the intake and pools in the turbo intake tube until fired up and sucked into the intake tract, intercooler and then the engine.

If you look at my first post you'll see how to run it down below the running board. I get rid of the valve entirely as it takes 1.5 lbs of pressure to open when it working like it should, when it freezes shut of course the pressure is much higher in the tank and blows the oil tank seal.

Just as has been talked about however, if you roll it over you run the risk of loosing oil easier without the valve if the engine has been shut off. If you loose oil it will run out the bottom of the hose and not go thru the intake at least.

However, if the engine is running on the stock system and its on its side or top, you will also loose oil thru the valve. The stock valve is designed to be open if the engine is running, and if its running with the stock system in place the oil is pouring into the intake.

Joe, I have run this setup like I said for well over 8000 miles between my Doos and now the Winder. IMO the hanging below the board helps keep it free of ice as its in the exhaust stream, plus I don't want the oil mist and smell on my suit and boots.

The one ice up shagnos had is not common at all. He had to have done a bunch of short trips or something for that to happen.

Like I said earlier, if your concerned about ice up on the end of the hose, cut a 1.5" long slit in the hose in the part of the hose above the running board for a pressure relief.

If you look at a Apex airbox, it was common for them to ice up on the end of the hose in the airbox, they had a slit cut in them for this reason, same for the 1200 Doo, a slit cut in the hose for relief should the end freeze up. This is very easy to do if you're running this modification.

Cut a slit length ways in the hose just above the running board.

Thanks Mike I think I will go this route and see what happens. First and foremost I don't want my oil tank seal to blow and if I put the ROV back in that will probably increase the chances for that to happen.
 
Im sure one could route the hose to the bellypan below engine, and just let it drip into the pan, it surely would not freeze there but would be messy id think.

I just keep eye on mine and its never froze up, can always just tap on it to break off any ice on end.....likely a combination of deeper power and not enough speed to make heat in the vapors. Starting and stopping alot allowing ice to build up..... Also the routing is important, I have mine tight to oil tank so its warm area....

Maybe Hasselhoff should post pics.

Ultra Black silicone, and leave it sit at least a day before putting oil in.

I find this one to be excellent maximum oil resistant seems to work real well
