This was the second time I remove the supercharger from Desire for inspection. Last time I remove it the power take off gear housing as bone dry without oil. Surprisingly the gears showed no sign of premature wear. I fill up the SC with GM SC oil and had since driven on track many times. To my surprise somewhat, the high pitch noise did not subside with the replenished lubricant. Fearing the PTO housing seal may be leaking and all the oil got sucked into the SC compressor housing I remove the SC for the second time to investigate.
