A couple months ago I started to hear a high pitched, siren like, sound which increased in pitch as the engine went to full boost. I noticed no change in performance, as far as I could tell. I don't use the car, my TR powered El Camino, that much, and there is no noise I can hear until I go into full boost. I decided to investigate today and found no play in the shaft, but one of the fins on the compressor side (TE44) is bent and curled back a bit. No other damage is visible. Just wondering if there is any downside to continue using it, and/ or should I try to straighten the blade, if possible, with a pair of pliers?
