Source of Engine noise

[alex61089]

hey guys i posted up a thread about noise coming from my engine that makes it sound like a diesel. After looking over my engine and listening to areas i've pinpointed exactly where it's coming from. I'm not sure what it could be so if you guys have any ideas let me know but....

The noise and vibrations are coming from the drivers side underneath the timing belt cover. I felt and listened to the drivers and passenger side and there is a significant different, could perhaps one of the idlers be lose?

The idler bearing could be the cause.Only one way to know for sure.Tear it down and see if the pulley is the cause.
