I was reading this article for the 4th gen and was wondering do the 3rd gen 4runners also have a loop? I couldnt find anything on this and wanted to know if anyone else noticed. I am asking because i have a leak on top of my transfer acse and i did noticed a breather nipple on top of my transmission and a tube coming from the top of the transfer case that at this moment goes no where.

here is the article btw

just curious but has anyone dropped a t-case and noticed anything?
