HPOP is in the valley at the front of the motor ( in front of the fuel bowl). Look deep. If it and the ICP are fine check the two hoses coming of of it. Next follow them back to each head and check along the heads as there are several plugged ports that could be leaking also.
There are two sets of turbo O-Rings though generally only the lower ones (between the pedestal and valley cover) wear and leak.
Also, if the turbo's never been messed with put your hand on the EBPV (exhaust butterfly between the turbine housing and down pipe, under side), then move to the actuator rod, follow it back behind/under turbine to where it meets the turbo pedestal. Feel for oil.
Since you're not complaining of drivability issues, besides the leak, I'm leaning on turbo leak.
