"Whurring" Noise

Hi guys,

Only just got my 197 back on the road this week, after months off the road. Changed the AUX belt (full kit) while It was garaged.

Back on the road all fine, except this morning and again at dinnertime; started from cold when reving the car, I am getting a "whurring" noise. Goes away once car warms, but certainly does not sound normal.

Any ideas? As I thought the AUX is autotensioner, so surely not too tight?

Thanks,
JAM
 
without hearing it, the noise could be a few things. could be early signs of the dephaser, they go quiet when warm.
