Just a suggestion on keeping the oil where it should be. If you remove the A6 for any reason, oil a new or rebuilt, it should be kept with the oil pan down just like the engine in the car. Oil will seep past the reed valves and other shields in the compressor and into the cylinders. That can blow the oil out the cylinder reed valves and out the high side. That can limit the cooling.
The compressor has it's own oil pan, oil pick up and oil pump. About 4 OZ. is minimum of the 6 OZ it holds in the pan. What can happen is the main shaft bearings,thrust bearings, and front ceramic seal will be starved of oil. The rings can get oil thru the R-12 or whatever you are running.
The ports should also be sealed. they don't sit on the pan without falling on their side, so you need to keep them upright.
For some reason mineral based oil collects moisture. Never rebuilt one that didn't have rust in it. If you think this has happened keep it right side up for at least 6 hours and turn the hub, (not the pulley) in the proper direction to clear the cylinders, actually either way will work.
They will survive and have suffered from this problem, but being ANAL doesn't hurt. Also there is a way to drain oil if you suspect you have more in the pan than needed. I think over oiling gets in the way of cooling.
This over oil check will drain the excess oil without loosing your charge. That plug on the pan is actually a over oil drain plug and is drilled to let the gas push the excess oil out before the gas escapes.
