I would like to cap off the current breather tube and install a pcv valve in the tube. In addistion, i would also like to use a solid cap on the valve cover rather than a breather cap. Does anyone have any experience with this type of set up and know if this is sufficient ventilation for the motor. It looks like later model motors have a similar set up shown on pg 28 in the 1947-1954 factory assembly manual
