HI
My
JCW works mini (2003) had a strange 'rattlely sound' on tickover. Appeared to come from the top of the engine around the supercharger area.
Mt Friend (a mechanic) suggested he thought it could be bearing noise - suspected supercharger bearing .
We have now romoved the suspect part.
When we start to rotate the blades their is a destinct 'click' . If rotation continues no more noise.
Is this normal ??
If you wobble the pulley from side to side the 'click' dontinues. We were wondering if the gearing may be a little worn. Car has 50k ish miles.
Otherwise seems to rotate OK , Does any one know how to diagnose a supercharger problem and how easy ought they spin?
Cheers
