Hi: My Big16G turbo just ate the hose coupler ( the short piece of hose that is sandwiched in between the compressor inlet and the intake pipe inlet hose ).

I think this is install mistake on my part, most likely. I probably did not have the spacer all the way into the compressor inlet.
So, yeah, one day I come home from work, and the turbo stopped making boost.

When I pulled the inlet pipe out, there is a small rubber piece that got stuck on the compressor wheel. I was able to pull the small rubber piece out. I also removed my intercooler and piping, and removed all the small rubber pieces! Yikes!

I'm glad that the intercooler seems to catch it all, as I don't see any rubber piece of my GM MAF ( blow through ).

So, anyway, the compressor wheel now spins fine by hand. Also, at idle it is fine.
However, if I rev it ( even at idle ), it will start making a loud whining sound.

What do you guys think ? Can a compressor wheel get bent from just a flimsy rubber piece ? What else can be broken on the turbo ? ( FYI, I took out the compressor inlet and outlet pipe, and narrowed down the noise to be coming from the turbo. It's nice running in blow through setup, because you can unhook the turbo completely and it still runs )

Is it worth rebuilding my 16G ? It is ported and clipped already.
 
The 'rubber spacer' goes on the outside of the compressor housing, not the inside. You do not need that rubber piece on a 16g. Even a small piece of rubber could damage the compressor wheel, It spins really fast and at the speeds it spins, Even something little going in there could damage it.

Yes, on the outside of compressor housing, but inside the turbo inlet hose. For sure I didn't put it inside :D But, thinking back, I might have not slide it all the way inside the lip on the compressor housing ( the outside part ).

So, to rebuild it, I will need a compressor wheel and then rebalance, correct ?
I assume my compressor wheel is slightly dented and/or chipped, and it is no longer balanced. That's why it only makes the whining sound when it spools up, and not when it is spinning at low speed during idle. Sounds about right ?
