hey man, i know what you mean, my breather rusted off too, you need to get another cover with an ok breather from another diff, if you wanna swap it, yuo have to make sure that the actual nipple isnt rusted, if its not, you can swap one over from you open diff, if so, get another cover it’d be easiest for the oil check the other thread going right now theyre talking about it ---

I dont see why it needs to breathe. thats good, it needs to breathe when u take turns like a maniac and when the temperature outside changes, you guys can try putting a really fine metal mesh sheet over it, wrapping it around the nipple, and hoseclaming it on, possibly two layers, or maybe a really mini k&N breather for it hahahah ---

hahahahahaha not evvvven, i figured it was a breather… but if it needs to breath taking corners like a maniac then the k&n would get drenched,and that mesh would alow particles in the diff= no good and i noticed the cap HAD a spring and a rubber washer in it…so i dont know how well that was breathing :roll: …but if its on my open diff and its not rusted to anal,then ill swap that in. if not ill order it at nissan for like 2 cents
