Metallic grinding whirring!!!
Started yesterday, a metallic squeal which quietens down but doesn't go away totally. It is rev related, increases if you increase the revs. Seems to be coming roughly from the front of the engine bay which I'm guessing means water pump. Its difficult to pinpoint the noise though!! Initial thought was alternator as it sounds a bit like a dry bearing, whizzing type sound ?!?!?
Tried squirting a bit of wd40 around just to check its not a belt noise, no luck.
