Depends
The older models with the schrader valve , the cap needs to push down on the pin just a little vent out the air .. The schrader valve was a secondary valve ... Seems like they added the schrader as a safety valve ...Cap fully closed , open or missing the vent is closed ....
i cut one apart years ago when this question came up ...
In the newer models the schrader seem to be deleted ...
Second note.... From inside their paper work , you should set the cap just slightly loose . They don't want a rush of air, water and dirt to foul the valve seats ...There was an error rendering this rich post.
