The mechanic installed the waterpump, and that took away a lot of the noise. Then he flushed the oil in the supercharger and put new oil in it (he said it was 1/4" below the threads...it was low). He said when it wasn't in idle you couldn't hear the noise at all and there was only a small noise when it was in idle. The noise couldn't be heard when the hood was closed.
He did advise to have a little nest egg building so if in the future it went out, it wouldn't be such a surprise. Good advice I think.
Also, you all were very helpfull in making me feel that this mechanic was capable as he said many of the things you all offered. Many thanks to you!!!
DeathRat, I will be emailing you later to get the information so that I have it on file, and if I need that nose replacement down the road- I'll have the info...
