Thoughts on this engine noise (Video inside)

[Scott™]

I have a rattle from what I can only think is the Aux belt area. Had the front grill off today so it allowed me to get in closer.

The noise in question is a higher tone rattle that is prominent at the very begging and near the end of the clip.

It's like a metalic rattle.



​Any thoughts would be welcomed.

Bump on my engine noise.

Alternator, water pump or dephaser at a guess !?

When were the belts last done...?

​About a year mate.Cambelt dephaser? That was done last year.

Sounds more like alt/pas/aux related than dephaser. Tried running with belt off?

 

[Scott™]

I haven't mate.

Sorry I cant hear what your on about. that sounds normal to me... (will have another listen).

Edit - ok after another few listens, I can just about hear something that sounds like a worn alternator bearing (something like a worn and dry ball bearing race).
