timing belt screaching ?

[wil0]

yeah, the roller bearings for the cams looked fine when i did the cam chain so im confused. Its strange that it only does it when i tension the belt correctly, its a new tensioner, and it did it with the old one too. it sounds like its coming from the top of the engine, but i cant be sure. i have used a special listening device (a coal chisel), but cant really find the noise. When i drive the car, i can hear it as a whine.

You dont have roller bearings for the cams and have either of you checked to see if theres any evidence of the belt rubbing on the belt cover as that sounds like the more likely problem if its not the tension or the tensioner.
