I had the cap vent problem described by Pat. I drilled through the original vent hole in the center piece. I tapped the hole for a small screw and locktited in place. This locked the gasket to the cap center so it could not rotate to block vent.
I then drilled a new vent hole on the opposit side of the original hole. Be careful to only drill through the center and not the outer cap.

This has worked well for several years .
