excessive 340 crankcase pressure

I am saying the PCV valve can not be mounted on the top of a breather. Looks like the bottom of them two breathers is open to the atmosphere.The PCV must be sealed at the mounting in the valve cover with a rubber grommet and the breather must be in a different location on a valve cover and/or on the other valve cover. PCV sucks air out of the motor and the breathers let air in or out as the crankcase pressure requires.
