I had a God-awful rattling in my car when I first got it. as time went on i was able to replace things.

1. Crank pulley&balancer (it is one part, the balancer is incorportaed into the pulley. $250 just for the part. passenger wheel has to come off and much work done to replace it)

2. idler pulley (i think mine was the inside one on the supercharger belt, but yours could be either, or even another pulley.)

as i said in my other post, even if you have someone else change your supercharger oil, youre only looking at maybe $30-$40. seems a small price to pay on something that would cost A LOT of money to fix if it broke.
