I’m unsure of this, but can I drive the grommet for the PCV valve into the hole for the breather (see attached picture). I’ve been under the impression that the grommet wouldn’t cover the surface area left by the slots for the tangs. If the PCV grommet could be driven into the present hole without any air leaks then my problem is solved.View attachment 1715524122
There's generic and other (non mopar) breathers, caps and PCV arangements out there. There's several that will use the 'twist lock' hole like that and take a PCV valve. IIRC look at F*rd, as well a Mr Gasket and Stant catalogs.
