Hey guys so I believe this is why my car isn't idling right as you can see from the pic the pcv came out of the valve cover. so i just put it back in and tapped lightly with a hammer on the back of it. however it keeps popping out of the valve cover. Im not really sure how to fix this or what new parts i need can anyone help?

 

Idk if its available seperatley but you can replace the grommet it sits in, glue it or tap the hole and put a barbed fitting.
