i definitely would NOT recommend pulling anything in the puck that could stop up or restrict flow and change blowing a seal out. That would be an expensive learning curve!
There is a small spring between the puck and the rubber diaphragm. I think it acts like a regulator to prevent too much suction in cases when the turbo is at very high boost levels and pulling high flows from the puck.
Its a complicated little item the way the flow path is designed to try and prevent oil from leaving the puck.
I don't fully understand the "J" trap on the drain unless it is to create a different pressure zone on the drain side and keep the puck from sucking on that side?
Pipe cleaner inserted in drain hole and "J" tube for clarity.

WWDiesel, thanks for posting the photos showing the loop seal and drain hole in the cam cover. I was going to take photos of these when I did the next timing belt change in a month or so. Photos hopefully give a clearer understanding of the setup.
