Madness Crankshaft Pulley

Have a noise from below which is most noticeable when cold. When the engine is at running temparature the noise changes butis still there. My Mechanic says it could be the Crankshaft or Alternator but wants £40 just to look at it. Any feedback would be helpfull. And will this cause any more damge to other components. ?

Its probably the aux tensioner BUT it could be lots of things. I am sure you appreciate that trying to diagnose noises via the internet is rather tricky. Some of these things include problems with the cam belt/water pump which can cause expensive damage. Thus, you need to get it looked at. When was your cam belt last changed?

been a 2.4 JTD is most likely the crank pulley or Aux belt tensioner, be prepared to open your wallet widely.

BTW have more patience when posting at 5am UK time, alot of us tend ot be alseep at that time of the morning.
