Oil control rings shot?

I've given a DIY rebuild some serious thought, and if BNR tells me to go screw myself, I just might give it a try.

Out of all the nice Garrett (rebuild) parts, it's one of the worst - the thrust bearing come a close second.

I dunno if there is a trick to get that compression ring seal to install correctly consistently, but I haven't figured it out yet.
You got the blasted exhaust shield bell cup loose and getting in the way, and the design of the seal being square-edged don't help with it going in nicely!
If you end up tapping it in - which is the case most times - it's probably damaged from that light tapping.
I use LOTS of oil to try and get the seal to snap into place, and that causes a big smoke show on the initial start up...
This can help sometimes, but it's still not a guarantee!
Then you end up crossing your fingers that the smoke eventually clears up soon!

And this is exactly the kind of stuff that worries me about trying to rebuild it myself... Good info here Ted, I've done some web surfing and watched maybe a half dozen "how to rebuild your turbo" vids on Youtube, and naturally none of them covered these "gotcha's".
