1997 Grand prix GT Engine Noise

[badbob56]

I am trying to find out what is making a screeching
noise coming from the engine compartment of my Grand Prix.
It sound like it might be the idler pully, water pump or power steering
pump. All have been changed, the noise does not start until the engine warms up, and then it sounds like a squeeling belt or bad idler pully,
that is why I had them changed. The Mechanic finally pulled the belt totally off, after the car warmed up and the noise continued.
Could it have anything to do with the intake manifold?? Any help would be greatly appreciated.

Yes It seems normal, I did notice that when I removed the oil filler cap while it was running that the motor died.

does the noise get louder or change pitch w/ the rpms

Yes it does change, It seems like it is coming from the passenger side, that is why we changed the water pump and belt tension pully.

Finally found out what was making the noise.
Intake manifold gasket was leaking, I think the intake manifold is a common problem, but mine was being sucked into the engine.
Good thing we found it could have caused more serious problems.
