First thing i would do is take the belt off, and see if the noise is still there. Im willing to bet you have a bad water pump bearing or a bad idler or accessory belt tensioner. Take the belt off, and see if the noise goes away, then go from there. If the noise is still there, then you have an internal engine noise.

you mean take the belt off and spin the pulley by hand to see if the noise is still there. im kinda confused.

He mean remove the belt and start the car. If the noise is gone then the noise is from the components that driven by the drive belt. Yes, you can run the car without drive belt for 2-3 minutes. We do this all the times to check for engine noise.
Yes, you can remove the belt out and spin each pulley by hand, alternator, idle pulley, power steering pump and water pump(2J engine). You probably has a bad belt tensioner like RT said.

ok so i fixed it, it was a bad bearing on the water pump. replaced the water pump, replaced the timing belt, and fixed the timing. put it all back together and WOOOOOOOOOOOOOOOOO HOOOOOOOOOOOOOOOOOOOO no the car has no engine noise, and its idleing really smooth. turn on the engine and sit in the car and you cant even tell if the car is really running or not. anywho thanks to everyone, for the input,

was it a diy or did you take it to a shop. if you took it to a shop, how much did they charge you? im having the same problem, but the noise from my engine is a little bit louder. thanx
