Default FSE450 2005 crank case brether

Hello, I hope to get some information from knowledgeable users. crankshaft breathing tube makes strange noises "flushing toilet" when engine is turning, but not when running. And also leaks oin when in high revs. Is there problem with the piston rings?
the bike starts fine, runs great, no knocking noise, only the pressure in case

you can hear the sound when i turn engine and stop. in this video
