<VV> Differential pinion adjuster O-ring

Does anyone know what happens if the o-ring is missing from the differential pinion adjuster? This is a 4-speed manual transaxle.
I just finished reassembling the transaxle and installing it on the engine when I discovered that I did not install the new O-ring. As far as I know, there is no o-ring on it at all.
It looks like a small amount of oil may seep through the threads until the oil levels in the transmission and differential matched. I am estimating 1/4 inch between the bottom of the transfer hole (between the transmission and differential), and the bottom of the pinion adjuster threaded hole. So the transmission may drop 1/8 inch and the differential rise 1/8 inch after a long sit. Then during operation it should pump back to the transmission until proper levels are restored when it starts running through the transfer hole.
Even though it seems fairly inconsequential, I will probably try just draining both units, pulling the transmission back off, removing and reinstalling the pinion adjuster ring (with the o-ring this time) and reassembling.
