Your car's grommet has a plastic n ipple inside it to connect an extension hose to the pcv valve. Otherwise, it is standard Mopar. Pop the old grommet out, cut it to get at the n ipple and swap it to the new one. In the photo below, I was tinkering with a larger vent hose idea.
I recently was dealing with the same thing regarding the 90 degree n ipple at the from of my driver side valve cover.
I even contacted Dorman and they don’t have anything with 1/2” female on both sides.
Anyone here have an idea for me?
