edit: its the cylinder head plug

k i just replaced my valve cover gaskets and cam adjuster seals thinkin it would fix my oil leaks but little did i know this whole time my cam plugs were leaking too. how do i replace them? please tell me i dont need to pull my valve cover again. do they just pop out the back if i can get like some pliers on them? i can reach my hand back there i just dont know how im supposed to go about pulling them out...

 

maybe just a guess? lol

 

Ill take a guess....I think that you have to get a special tool and then they unscrewed, and they come out like a threaded freeze plug dont know if they have a limit on how far they go back in
