hi guys i just bought vitz 2006 1.3 FL. i m observing 2 types of noise from the engine n i cnt get my mind off it as i m v choosy in these matters.
1... at idle RPM the car produces some noise as if theres some thing in metalic box clinking while rotating ( dnt know how to explain the noise ) its v minute noise but still i want to get to the bottom of it. it only comes at idle RPM and if u remove the belt it goes away so it means its not engine noise its comming from the accesorries the belt drives.
2... when i accelarate from idle to 2000 rpm or above the engine produces chir chir sound (its more like a mixture of knocking and loose belt noise combined) but it only comes between 1500-2000 RPM not lower than tht and not higher thn tht.
help wud b highly appreciated
