Just spent a couple hours trying to see ho that thing would turn.
#1 I have no f$%@ing clue how the thing would turn
and
#2 the wastegate solenoid is solidly bolted to the compressor housing and it needs to be right there for that metal rod to open the wastegate. Without being bolted to it right there it the solenoid would just move on the end of that rod back and forth since the wastegate inside the turbine housing is pretty friggin stiff. So even if you could rotate it you'd need to do something to hold the wastegate solenoid in place. *sigh*
Wow, that makes me sound pretty smart huh?

Well, just get a few wrenches and socket set and a T25 and you could figure the same things out. That's all I did -- go at it
