Oil in intercooler and hoses

[race24x]

Is it normal to find some oil in the charger hoses. I pulled one to clean it and found oil, so I pulled them all the way to TBs and there is oil in them all. I haven't used any oil between oil changes. The sled is stock boost etc. I attached some pics. One is from right after intercooler the other is just before throttle bodies.

The R.O.V vents into the intake tract. Oil getting into the the intake is one of the reason guys are deleting the R.O.V

This is the from crankcase ventilation via the oil tank/roll over valve that taps into the front of the plenum.
Oil mist/vapor and moisture, get routed in there, one of the reasons guys are bypassing or eliminating the ROV.

Thank you guys. I know on my Seadoo this could eventually clog the intercooler making it much less effective

The vent line from my nytro vented to the air box. The air box was always lathered with oil and would drip out the bottom. I can only imagine all this oil will collect in the inter cooler on the sw
