You've never seen a valve cover breather before?

Granted, they're usually separate from the oil fill cap, but still.

tarbo cars have valve cover breathers, but usually they feed back into the intake.

It has a check valve in it. It reduces the fuel economy benefits of the PCV system but reduces oil intake into the intake manifold.
