Tinkley Funny noise from engine 2.4 350

Hi there just thought I would post what was causing this annoying noise now that I finally managed to sus it out. After changing the aux belt and tensioner and the noise was the same I was left with a good tensioner and pulley roller so I took the belt back off and swapped the good pulley roller with the other one still there on the engine and belt back on and............... silence. Ah peace at last no more noisy tweeting birds.
