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.
I was going to suggest the same thing, but I believe that oil line on the tank is below the oil line. if it is, just plug the hole on the tank and do what JF suggests.
