Found that on google images, are you talking about the one with the tube going to the intake manifold?

If so, that is the pcv (positive crankcase ventilation) for the b18b engines. They do it differently on b18a's so the valve covers don't have that. If you are running a b18b engine, I would recommend running the pcv properly unless you are running a breather/catch can setup. Plugging a pcv system will cause blowby and is not good for your engine.

If that's not what you're talking about, sorry I couldn't help.

 

i don't have the plug thats on the manifold cuz it's a b18a motor i talkin about the hole on the valve cover can it be blocked off with a plug? and is it safe
