Turbo Exhaust Leak or????

[Just a Six?]

Hopefully I can post these pics. I was playing with the BSTC & made some progress I think but this is what I found under the turbo sheild. It sort of sounds like an exhaust least when cold but even with a Stethescope I still can't say for sure it's leaking??
Nothing on DP seal. Nothing on header - turbo gasket seal. Just on the top from oil fitting area & the cover is filthy on the inside at the top area. It's exhaust & not wet oil.
The cold side wheel looks like brand new & no play at all. never removed the DP. had enuf for 1 day as the back is starting to hurt after 3 houirs bending over.
*The Only Peice I cleaned was part of the Blue Nut/fitting. The Blue line was clean.
The spot on DP isn't exhaust just a shiny spot.
I didn't touch the fitting yet but I will after I spray it with brake clean.

where does the smoke come out when you dribble something into the throttlebody?

Or suck it thru the fuel regulator hose?

Since BPG I haven't touched it except BSTC swap. After cleaning the area I'll see what happens after some drive time. Then I'll suck some trans fluid thru FPR vacuum port. It's weird because altho it doesn't look like oil residue that turbo is pretty hot & may be burning off a slow leak up top? Probably time to check all the nuts/bolts in case some may be a bit loose from 3 seasons of driving.
