My car is not boosting, checked the BOV, ckecked the wastegate...there was a problem but got that fixed, still no boost. I am hearing a whining noise when the boost has to happen but nothing, it does not go over 0 bar boost

No boost pipes are off, if there was a boost leak ot would have had some boost at least, nothing, so the next thing, shaft snapped...but if that is the case, 3 questions, why does the compressor wheel spin on idle ,
Why do I hear a whining noise when its suppose to boost and why is there no smoke on driving?????

is the turbo soak in oil?

how much play is there?

when I first got my S13 my T25's compressor wheel used to catch on the housing making a weird noise and not make any boost. It also never smoked oddly enough.

I checked it now(don't know why I did not check before) has a decent amount of play forwards and backwards(2-3 mm), from side to side little play, that indicates that turbo is not in the condition it was, still...does that mean the shaft has snapped, when I started it cold a lot of oil smoke but went away as the car got hot, obveously the seals on exhaust side has some damage but compressor side shows no oil in boost pipes....still I am not convinced the shaft snapped...in any case, turbo will have to be replaced, just don't want to replace the turbo and find the same thing...no boost.
