Cavalier 96 motor noise

Good morning, I have a situation, with a 96 Chevrolet Cavalier, it has a noise in the engine. I understand that all the cavalier have this noise, it seems that it was the time chain but according to me it is something else, to see if they guide me ...

Well, we will stir some cencillo we first remove the band should be just one although I remember this moves the water pump alternator The A/C compressor if we have the car well if the noise is eliminated because it is one of the pulleys that moves this band if the noise persists is something of the engine and looking for a mechanic there is no other, well luck

How much km you have traveled these engines tend to stretch the distribution chain and play on the lid that can be the noise that you feel attention that you can eat the cover of the chain and apart from power how it is going well or decreased.-
