Ok, the Transfer case only has one oil pump, and it's sole duty is to pressurize the outputshaft with oil. Once the oil is inside the output shaft, it only has one direction to go and that is to the front of the shaft where the low speed gear cage bearing is. Without this, the cage bearing is a sitting duck high above the oil level in the transfer case with no means of lubrication. Bobby Long is very fortunate that in high range torque is not transferred through the reduction gears, and that is why they are not an immediate failure.... yet.
But anyone cruising around in low range with a Bobby Long output shaft is risking burning out the low speed cage bearing in the transfer case. Toyota went through a lot of development putting that oil pump system with the two oil splash trays and the oil pump seal for a very, very good reason.
Therefore, it cannot possibly oil "the same as stock" because you have eliminated the oiling system. You might as well remove the entire oil pump and then go on a road trip. Have fun!

Further explanation of why putting longs output in completely eliminates the oil pump....
