BIG oil leak- where do i start?
 

I have a recently acquired 98 v70 awd. The PO put in a new ARD td04-19t turbo only a few thousand miles ago. This may or may not be related.
Anyway, there is a LOT of oil that drips down the engine to the rear of the car, moreso on the drivers side it would appear. The exhaust doesn't seem to be spitting it out, so that's good.
What are the usual suspects to inspect?
I plan to clean it up and have a look, but there are so many pipes and stuff in there it's hard to know where to start. I assume I'll look hard at the turbo feed and return pipes, but they are so hard to see with the awd in there.
Appreciate any help, and I will update.

I'd start with inspecting the turbo oil return seal. when that goes it makes a big mess. Also inspect where the return line presses into the block.
