then its probably a standard circular grommet. if you take the old one off, go to autozone or any store like that, go to the dorman HELP section and you should be able to match it up. Autozone near me has a hole selection of pcv grommets that I know for a fact would have a match for your valve cover. my valve covers are the same, but the passenger rear is my breather and its the same as the driver front, except flipped around so its in the back for the proper air flow.
I actually got one of the push in breather caps for it from autozone, they come in 2 different standard sizes i believe.

I should clarify, my passenger valve cover also has the oil fill which does technically make it different than the driver. otherwise yeah
