This is what I’ve done to get rid of the problematic valve. Just a hardware store 5/8" ID hose wrapped with foil heat tape, looped it up and over down to under the running board. Let bottom hang and inch or two below the board. You can see how much blowby you have also.
I plugged the line where the stock hose went into the turbo intake with a rubber 3/8" ID cap stretched over the intake turbo tube nipple and clamped.
Now the intake is not getting that blow-by exhaust and no worry of the supposed factory "roll over" valve sticking shut and blowing out the oil tank seal again.
It worked fine on my turbo 1200 Doos for years this exact same way.
I was going to install a 1200 roll over valve but haven’t yet as the space to do so is pretty limited. It’s been over 20 years since I’ve rolled any machine and am not to worried about it not having a valve, for now anyway.
Not telling anyone to get rid of it, but I’m not going to have my oil tank seal blown out on a trip. I’ve already sealed it once as it was leaking.

This is my latest creation as one sled I did last year had a hose kink at the loop. Don't use heater hose either as it is not compatible with oil, make sure to use 5/8" fuel or oil line.
