Looks like you may have a seal on the turbo leaking a little oil. I think you can be sure it is coming from the engine as that is where the oil comes from to lubricate the Turbo bearings. Not sure what you are looking for -- suggestions -- that it to someone who can determine what if anything needs to be done.

I doubt it is anything inside the motor. There is no direct connection. As you know know
the turbo is driven by exhaust gases and then compresses fresh air into the engine.

Did it ever give you a puff of blue smoke when it started before you started taking it apart?
If it did then the turbo seal is the most likely candidate.

The problem on all this V engines 280,300,320,350 leaking from that hole is oil cooler seals. I have change them and no leak any more. But it takes at least one day work because needs to take out turbo, air intake system and complet other equipment which betwen to engine bloks. The oil cooler is in the end down betwen to blocks.
