I don't know exactly what to do. Its not a belt squeal sound and spraying where I did several times did stop the noise. This specific sound, and there are two sounds in this topic. appeared after the belt was changed. It will eventually come to failure. In the mean time I'm looking around.

Note if you pull the injectors to obserbe fuel delivery...make sure you leave the plugs in and disconnect the ign. Believe me

Maybe a water pump going out? The different stress put on the wp pulley by the shortened belt may have masked it for a while. I had an odd metallic sound from the front of my engine mostly at idle, but got gradually worse. I was convinced I had a lower-end problem, like a bad rod bearing or something major. Turned out to be the water pump. First time in a long time the "worst-case scenario" was not the culprit! Yee-Haw!

Use a mechanic's stethoscope and troubleshoot the problem with and without the belt.
