help identifying oil leak... turbo perhaps?

[kstop]

Hi. I'm in the process of changing my angle gear on an 02 xc70. Although the angle gear was bad (input splines stripped) I thought the oil in it was a leak from the gear, but that appears not to be the case. Looks like oil coming from turbo? I read about oil return line and was going to try replacing those gaskets, but honestly, that appears to be dry and not the source. Did pcv about 5000 miles ago...

Here are some pics if anyone can help. Sorry, I'm not a mechanic, just learn about fixing problems as they arise and want to get this taken care of while angle gear is off. Also want to start putting this back together, so if you think leak could be done from the top, I could continue on and then deal w leak once everything else is put back together. Thanks in advance for your help! btw, hope images loaded, have been trying all day and constantly getting error messages... so maybe someone has advice on this issue too?

In case anyone else has this issue in the future, looks like the oil leak is coming from the rear cam exhaust seal and dripping onto the turbo (which made me think that was the issue)
