If the oil dripped out, then I would concur with your conclusion that the turbo oil seals are failing

It wasn't dripping but there was fresh oil in the pipe into the intercooler. I wouldn't say it was excessive but there was oil in there.

Even the intercooler, if possible.

I cleaned the pipework from the inlet box into the ERG unit and I removed the butterfly which was caked in crap. I didn't go further as I need to get some new gaskets before I delved in further.
I have sprayed in some carb cleaner which may help clear some rubbish out.

My plan is to have the ERG unit and Inlet Manifold cover off so they can be thoroughly cleaned with carb cleaner so I can rule all of this out as a cause for the burning of oil.
Whilst this is all off I will also do the PCV diaphragm.
