That is the Compressor Bypass Valve, CBV. The CBV allows air to re-circulate within the turbo under conditions of high vacuum. This is to prevent compressor stall. If the CBV fails you will notice a "stutter" to the engine when taking your foot of the gas other than real slow.

I think you will find threads inside the rod where you can't see them.

After the long drive home with no boost, it must be a real thrill to drive this car with the turbocharger working. The Mitsubishi turbos used on the B230Ft are small and spool up very nicely. The later 1990 and on TD04s really spool up fast.

Did you see my post on turboshargers? Below is one picture from it.
