Pvc System Is a MESS!!!!

Hey whats up. I am rebuilting my a20a3. My pcv system all new, but the only thing is when i put every thing together there is a piece missing. I am try to find out what the part is called? It might be some kind of bushing, It is found in between the black housing and top hose that holds the pcv valve. It doesn't seal and i don't want it to leak its a hole new engine from top to bottom. Thanks for the help.
