t-case part - vent or plug?
I was filling out t-case on a CJ7 with fresh oil today and slightly overdone it. To my complete surprise the oil was coming from two separate directions: first, the usual - fill-out hole and another one on the top of the t-case, which I first thought was a vent. I started looking for the part to replace but so far I cant seem to put my finger on it. The hole is located right above the rear drive shaft yoke facing straight up. I found a few schematics on google but I neither would give me a clear answer. So, here it is. What the hell is that - a plug or a vent?
P.S. I wanted to make a pic but it's so up high so it wouldn't be visible.
