This just started a couple days ago, when I turn the car on cold there is a loud squeaking from the engine. I thought it may have been the belt but when I listened closer the sound was coming from the rear of the engine. It almost sounded like it was coming from the distro. This is all when the car is idling. When I start to drive the squeak is quieter, and when the RPMs get high enough I don't hear it anymore. Now when the car is warm and I start it up there is no squeak. Does anyone have an idea of what this could be?

 

Would it be possible to post a video of it with the belt off?
I'd like to hear it.
Since it's serpentine, it takes like 15 seconds to take the belt off.

 

I'd take the dist cap off and see if it's wearing evenly. Also, sometimes the shaft gets coked-up and oil can't get to the top of the shaft which wears the bushing and could make it squeek.

 

I looked under the cap today and everything looks good. How would I go about checking the top of the shaft...remove the distro?
