I screwed up so bad with the black TGP I bought a few years back.  The combo was never set and the factory tab was still behind the set switch.  I went to the city (Chicago) one day, and without thinking snapped the tab off to put my stereo face in the glove box and lock it.  After I did that, I realized I had messed up what was probably the last unmolested bit of the car.

Rebuilt my turbo using the killer write up I found on here and completely fixed my smoking problem.  I love this site!!!

Thank you so much for producing this writeup!!!  I rebuilt my turbo over the last couple weeks following your write up steps and the process went flawlessly.  I had the turbo off to replace the crossover on my TGP and figured I might as well give the rebuild a shot.  My car was experiencing a really weird smoking problem where suddenly, it would drop a huge plume of oily smoke, then clear up and randomly happen again.  I was hoping the rebuild would solve the problem and it did completely!  Huge props to you for writing this and to Google for finding it for me!
For the record, I got the Dynamic Seal T25 rebuild kit from http://gpopshop.com/ with the 270? bearing.
