Default V70 T5 oil leak

Best of evenings to you on this fine locked-down day,

My latest edition to Club £400 is a 1998 Volvo V70 T5 Automagic.

It has quite a bad oil leak. The whole of the underneath is wet, as is some splattering on the rear bootlid. Spectacular!

I took a look-sie with my peepers and its spraying all up the back of the block, but no seepage from the front crankshaft or any of the camshaft seals. I thought rear main seal initially, but from the angle and the spread on the oil ejection, my hippopethisuses is that a very fine spray of oil is coming from some kind of turbo seal, or perhaps a hole in a pressuried oil line coming to/from turbo.

When idling, there doesn't seem to be noticeable leakage, so I'm guessing it is a small leak that gets worse with oil pressure.

Is this hypothesis remotely possible? And if so, do these symptoms therefore eliminate a rear main seal issue, or am I just an idiot?

Of course, as this is the internet, I'm not going to provide any pictures. That would be too helpful (car is out of reach)
