So I wanted to get a good look under the engine cover so I took the oil filler neck off and a piece fell off. Its the part you pop into the hole that looks kinda like a gasket or somthing. its not the black ring it sitting on the bottom of the cap just below the black ring. Is that important? should I get a new neck. Can anyone understand me? I cant understand my self some times. lol.

 

I can't quite understand what you are talking about lol.. is there anyway you could get some pictures of it?

On mine I just removed the neck and put the oil cap back on. If a piece fell out of the neck, I wouldn't worry about it. Just throw the cap on and toss the oil neck
