Makes same noise with the serpentine belt on or off the engine. goes the same speed as the engine. no engine codes but idle is 100 rpm higher than usual and also fluctuates 30 rpms at idle source of noise is top of engine, around valve covers. still has great power/acceleration/start-up. just a very loud consistant chirping (I mean LOUD). I added a quart of oil but i never had an oil light pop on. 3.3L (not a flex fuel) 129,000 miles
To narrow it down, while the engine is running, don't get near moving parts, you can use a long piece of steel, metal, put 1 end on the valve cover, the other to your ear and listen for rattling. You can move it around to narrow down the source of the noise. It's like a stethoscope but works well. I use a 3' long screwdriver.

not good. u should check with a mechanic. might be a rod knock, if your lucky just a lifter. If it was ran real low on oil its probably very serious and should get checked asap.
SOURCE: 2006 Dodge Gr. Caravan. Loud humming noise upon
Misalignment of the belt, incorrect belt, worn or loose tensioner, Too tight of an adjustment (many service centers do this on purpose so when the belt breaks in it becomes properly adjusted, I do not believe in this philosophy), The belt is actually one long belt called a serpentine belt.....
