Almost looks like blow by gases coming through the valley cover gasket or front timing cover gasket right above the water pump. Your PCV plugged or the vacuum line between the PCV and intake broken?

Sounds like rings/ringlands unfortunately I would try a compression test, and then another compression test with a little bit of oil in each cyl before you tear it apart though. May be something simple.
Did this just start suddenly?

PCV needs vacuum to work. If you are boosted, you might not be getting vacuum to your PCV, so the gases build up in your crankcase and find a way out anywhere they can. You probably need to be drawing vacuum from between your air filter and turbo if you aren't.
Also, verify the hoses are intact and the valve isn't plugged or stuck

Looks like you have nothing pulling from the crank case, so your PCV is not doing anything. Try this equally crappy drawing for what should work to fix it. Eliminate the hose with an X through it. Add the yellow and orange hoses. The orange hose should connect between the filter and turbo for vacuum. You will need a one-way check valve in the yellow hose to make sure the airflow is only toward the throttle body
