My new '82 300D sounds like it has a supercharger
The 1982 300D Turbo that I bought yesterday has a strange whine when it is started and revved. The car also seems to idle way too low as if something is dragging. I have eliminated all of the belt driven accessories by disconnecting them and starting the car briefly, but the whine was still there. The car has good oil pressure, has the correct amount of oil and ATF (as best as I can check on a cold engine), and starts fine even with only 4 working glow plugs. The turbo is free and has no shaft play. Any ideas on what else could me making the noise? Vacuum pump?
Here is a video of the sound, you may have to turn up the volume at 00:12 to hear the sound. http://www.youtube.com/watch?v=aJxCjn27VUM
