No "click" from the waste gate.
That short sentence tells the tale. No click from the failing BOV means it has likely jammed. If the waste gate stuck shut you would overboost and if it stuck open your car would be loud but would still boost slowly at full throttle.

I took an old BOV apart some time ago and couldn't believe the nasty crud that results when those gaskets break apart.
