I have a 2000 Z28 that squeaks (from the engine) when first started in the morning. When the engine revs, the squeak changes (get's faster). Once the car is warm the squeak goes away. Sometimes if the car hasn't been driven for a while later in the day it will happen again, and again go away when the car is warm. Any ideas?

 

It's one of your belts, it'll have to be replaced, same thing happened to me and it was my AC belt. Dealership replaced the main serpentine belt and belt tensioner as well, but that didn't fix it, then they replaced AC belt and no more problem.
