Hi all. 

This noise is a puzzle.  
Its very much on the right hand side but hard to say if its high up or low down.

It only happens when the engine is stone cold and even then not every time. It will disappear after about 15 mins. The weather is cold at the moment so not sure if thats relevant.

I bought the vehicle just over a week ago so have no long term history of this noise. she's a 1999 reg with 44k on clock.

Here is a link to a video I made.

I just looked again this morning with a view to listening with a metal rod but, sods law, it didn't do it!

Any ideas please?

P.S. I think thats the injection pump timing belt in the video. I have a sense that it might be the culprit. The noise seems to be about twice/sec which seems to slow to be the crank shaft.
