6.6L Noise/Squeal

[silvdur]

Approx. 45,000 miles
at around 1,300 rpm ( lasts only approx 50 rpms )
I get a squeal / squeak. It seems to be in the area of top rear/right side of engine.
Any ideas would be greatly appreciated

The idler/belt tension pulleys have produced these sorts of problems. Remove the belt, and check all of the belt-driven accessory bearings for smooth turning. The belt tensioner though is the likely suspect.

Squeal / Screech Noise:

This noise is noticable in Park accelerating thru 1300 rpm, and drive conditions. This is the only time the noise is noticable. I used a stetiscope around pulleys and all of them sound different.

Has the belt gotten wet lately? When mine gets wet it squels. Just my 2 cents.

It sounds like the noise is in the turbo area.
