Overspeed on Rear Turbo

Hey Guys,

Did some maintenance today and finally got an endoscope down the intakes to see what 86k miles (60k at 17.5psi) looks like. Need some advice/opinions on how bad the overspeed is at the rear turbo. Maybe @VargasTurboTech can chime in.

Thanks!

FRONT:

















REAR:















I am assuming the oil on the rear turbo is from the PCV. Hoping anyway... When knocking the turbos (front and rear) with the endoscope they didn't seem to have play, but I did get them to rotate some.

I adjusted the rear wastegate tighter by 2 turns a long time ago to get rid of some rattle. It worked, but likely it has been driven harder than the front turbo. I will need to tighten the front up.
