You should be able to grab the nipple with some plyers and yank it out, then tap the plastic baffle out & then re-install the nipple into the valve cover. Or worse case scenario remove valve cover completely to get it out.

I did that already but I want to install a new fram pcv on that valve cover

You don’t need it at the valve cover. Use the FV308 attached to the intake and connected to the valve cover.

I bought the fram pvc fv 237

I’d take it back & use the FV308 personally. No cutting the OEM hose, it replaces the weak plastic nipple with metal (upgrade #1), then it add’s it cleanly inline & looks 100% OEM.

They were talking about the plastic PCV.
I’m working on adding an oil separator. Trying to sort out the tubing connections and routing for both sides of the engine and location of the separator.

But that is just a fitting I'm talking about getting a better way to desperate oil in the pcv system
I'm getting slot of oil in the intake

The FV308 is a PCV. It replaces the straight thru nipple and puts a PCV into the system vs a plastic twirling piece of plastic. So you kill two birds with one stone. Replaces weak OEM plastic nipple & add’s a real PCV into the system without hacking anything up.

Ohhhh I see
