Run the motor and collect the oil from that line in a jar or whatever and see if it's full of bubbles.
It's not gonna skwirt oil all over the place so no worries about that. Not alot of oil goes through the turbo and there is no restriction orifice in the tank fitting so there's no pressure either, just a slow flow.

Do this when the oils hot too.

At least that may narrow down the source of your.. bubbles.
The oil coming out the drain of all turbos running at warmed-up oil temperature is highly aerated. This is true of all turbos. At the same time the oil flow is significant and HOT, so I won't suggest doing this.
