Sled is bone stock. Cleaned air filter day before last ride, unloaded and rode up into alpine with no smoking or issues. Stopped for a few minutes to gather before a climb into the zone we were going into. On the climb the sled was smoking really bad and running poorly. Open the air box and the filter is soaked in oil. The charge tubes have oil in them also. I have rolled the sled over numerous times this season and it has never been a problem. Seems to handle boost up to a certain point and then starts smoking up towards full throttle. Oil level is good. ROV seems to be sealing when blowing through it. What else can I look for before taking it in to dealer?

Mine are both aftermarket turbos but if your crankcase breather plugs the pressure will push oil up and burn it. I have heard of the rov plugging and giving issues

Your on a witch hunt, nothing wrong with it. Sounds like you like putting your sleds on their roofs, as long as you do that expect oil in the intake.
ROV needs to be serviced regularly to prevent hangups and put the sled on its top side oil will work past the venting system in to the intake and collect in the turbo cooler.
In this case the charge tubes will need to be disconnected and cleaned, your problem is being cause by a collection of residual oil accumulated in the intake and charge system.
Its my recommendation that you either change your riding style or go back to a two smoke.
BTW not even a 2 stroke likes being on its roof, too much roof time generally will lead to crank failure.

What’s all involved in servicing the rov? I’ve had it off numerous times and it always seems to seal. Don’t want to go back to 2 stroke, this thing had been too good this year!

I'll clean the ROV at the shop if i had the sled up side down a couple of times during a ride. I'll clean it no matter what every 5-6 rides to get rid of condensation milk (oil mix with water)that will collect, especially in cold temp's when its worst.
I use WD40 and soak it, then blow it out.
If my sled goes upside down for an extended period or multiple times in a ride then i also disconnect the boost tubes and air intake to clean out ant residual oil that might have gotten past the ROV.

Its all easy stuff to do and can be done as part of a pretrip inspection. At the same time i'll grease the zerks and air blow the clutches and check the rollers.
Check the oil and coolant levels, etc, etc.
