I know where the filler is, and that you need a 1/2 inch breaker to get it out.. However, at the very top side of my box I have a Upside down J kinda 5mm tube with a hose groove on the end. Now to me it looks like another oil filler. So, is it?

Look at this here. Thats what I've got on mine, whats it for? An oil cooler line or.. Is it for filling. Thats off an r33 box but you get the point.

correct me if im wrong, but thats a breather i reckon mate. -jimmy

Well that'd make sense too haha. Thats the first time I've seen it on an mx7..

yep its a breather.

It just seems strange that the pipe seems to have the little groove and everything to hold a hose onto it. I found a half inch breaker bar so I'm not too worried now I can put oil in the right way.

yeah, i have about 6" of hose hanging off mine, that way any oil that might drip out of the breather wont leak all over the gearbox, plus it makes it harder for crap to get into the box.
