It doesn't bother me (coz mine vented as well), but
just to let you know, that vented systems are illegal.
But mine's vented through the air intake on one side of the rocker cover and a small vent filter on the other one.
I've had this system on for about 7 months and have NO sign of oil in the T/B or in the filter,
as there's no real suction to talk about on the intake side of things.
It just vents into the air intake and out through the filter.
So in reality, I could gut the innards of a PCV valve (to make it look more proper), put that on the end of the rocker cover
that connects to the air intake and it would "probably" pass.
It actually looks like, that air is drawn through the small filter on one rocker cover,
through the crank case and out through the other rocker cover and into the air intake.
But it doesn't actually suck (it just looks like it does), it vents.
I'll put up a picture soon, of the set up I have.
