The bypass valve is there to keep pressure from hammering on the impeller blade and shaft when the throttle slams shut on rapid deceleration, so its purpose is to protect the turbo. I really wonder if turbo seal failures are related to driving a lot with a bad bypass valve. I drove mine for a bit with a bad bypass valve, with no ill effects, so I wouldn't worry excessively about driving it. Do order a replacement though, and until the replacement has been installed, definitely try to avoid rapid throttle drops when the turbo is boosting at or near full pressure.
