Hello every/all,
My friend has a 2014 Viper LTX that's having an oil problem.
The airbox seems to be sucking the oil tank dry. Then it leaks out through the airbox. He said it usually happens when it's cold (-25f or colder).
We can also see moisture build up in the oil tank (oil looks a little watery too).
My best guess is there's some type of blockage through the airbox and it's pulling extra strong from the crankcase vent because the air filter is clogged or constricted.
Haven't had a chance to look at it because it's thawing right now , but we'll take a closer look in the next few days.
Has anyone had a similar problem?
Anything we should look for?
Thanks

Just above the muffler there's a tank separator mounted on the frame ( oil lines are going to it and it has a shield around it ) take that off and clean it out , there's a ball in there that will freeze and oil will push out .

This same thing happened to me just after YamahaTim ,I'm not even boosted all stock.So can happen to all Sr Vipers , Was about -50 c when it happened had roughly 850 miles
Wish it had the same setup as the Nytro ,had Over 8000 miles on that not a single problem even down to -66 c .Would be nice if it had all Yamaha electronics ,sensors ,Wiring harness ,Oil tank,Dash.Even the dash freezes on the Sr Viper as it is like a little LCD TV but once warmed up it thaws out.

Thanks everyone. I'm pretty sure this is our problem.
Definite design flaw? This really is a MAJOR problem like YamahaTim said. I think Yamaha/AC needs to jump on this...a redesigned oil separator?
Hmmm, way to bypass it?
So this separator is just for rollovers?
So glad for this site. Very much appreciated.

It's definitely Enough to piss a guy off! Didn't think guys would ignore the post I made. But YOU will find out soon enough if you don't pay attention to this!

You may want to check for blockage causd by ice before you thaw it out.

That's a part of the reason I lost the motor in my cat turbo procross last month,darn thing kept pressurizing the crankcase and pushing oil into my air filter,till it started to leak by bad enough to feel the power loss.

Well I don't think there is a fix for it yet. So the 15's will have the same issue. You would think they would figure out something! Cause when it happens it's 2 quarts of oil in one second! So should try and make this a routine maintenance check! It's a lot easier than havering it happen while on a trip! For the stock ones should be pretty easy to reach. So while checking your chain case you should clean the separate rout as well. Better safe than sorry!

Freezing vapor in crankcase vents etc is not uncommon in cold weather. The lines need to be free of forming "traps" that can collect liquids and probably insulated. I assume there is no Positive Crankcase Ventillation and they use the dry sump to accomplish this?
FYI my old Polaris Sportsman XP700 had this issue. You'll never guess what Polaris' fix was...

I agree, but the Nytro had this in the oil tank. The Viper has a case. Water builds up and either freezes or the water and oil mix cause the oil the bypass right to the overflow tube and on the ground. It is a bad system. They need to do the same thing they did with the Nytro. PCV or what ever. Cause it sucks when it happens! No good

They are working on it. There's more to it other then roll over.
Yes thats true - mine did it before the sled was ever on its side and it was a warm weekend about 28 deg F and I was at WOT and it dumped.
