How do you removal the black oil filler neck on the valve cover. it looks like there is a plastic ring on the underside that should turn with the use of a spanner but no dice?

 

Oh, yeah, it'll come out, usually when the cap is difficult to remove. Use a strap wrench with a cheater bar.

 

I had to get a large enough channel-lock pliers to get mine off. I also doubted whether it was supposed to be removed but I eventually got it.

 

So for those of you that have removed the neck to replace the gasket....it just turns off? You don’t have to remove the rocker cover? When I replaced my head gaskets and cleaned up the covers, I was thinking there was a metal retainer that had to be removed from inside? Any help would be appreciated. Thanks.

 

Like @Lisa Bunch mentioned... It'll definitely unscrew off when trying to get off a tightly screwed on oil cap.
If you do use a wrench on it, be careful! That filler neck is fragile. At least mine was.

 

Mine was fragile as well, ended up replacing it because it broke when I got the channel locks on it.

 

Thanks for the quick reply! So I don’t screw it up, does it loosen in the CCW direction or does it loosen in the CW direction? I know sometimes it’s exactly opposite of what you are used to and you don’t figure it out until you break it.

 

@GregDisco2 Same as the direction as the filler cap (CCW), mine comes out some the time when I go to add oil. It is very annoying
