If you remove the alternator drivebelt and start the engine again to narrow down whether it is on the timing belt or drivebelt components, it does sound like a bearing is worn, likely the water pump if that has not already been changed.

 

Thanks
How do I remove alternator belt? On another car make it was spanner turning clockwise on hex nut on tensioner puller.

I listened to a few YouTube videos and this car is becoming similar in sound, like a canary cherping on, off etc.

Noise is definitely from timing belt area, when I go to alternator it is quieter.

What torque on alternator tensioner to nip up?

Assuming water pump, does the exhaust need removing from engine end to allow engine to be dropped a bit to remove water pump? This will be a garage job.

Shame the garage didn't call me up last time timing kit plus water pump was requested as this belt looks like new and done only 17k, albeit 7.5 years. Probably got another 2 years before touching.

Thanks
