Quick turbo questions
I finally received my turbo First question, on the inlet from the intake, the surrounding cylinder is covered with grease/filth. Is this normal? i mean, that means all that **** was going though the turbo and into the engine no?
2nd question, it has shaft play It does not move left or right but moves a very very little amount in and out. about 1mm or under. how long would this turbo last?
BTW T28 vs T25

The oil is fine, clean it up.
Shaft play side to side, as long as it is not hitting the housings is ok and normal.
Axial(in-out) shaft play is not good. I recommend a rebuild. You can do it yourself with a kit from gpopshop.com or wherever you feel like buying one.
Turbo spin over 100,000 rpm, you want them to be as tight as possible. Side to side shaft play is normal with journal bearing turbos only because the shaft sits on a layer of oil.
