yes I know another 'strange sound' post. :roll: 
I recorded a small movie file that demos the sound. -2.86MB

Its not the normal engine sound but the other popping' sound. I did a search - so I guess it could be water pump. The only think I know is that its not the Ac idle pulley as that's brand spanking new. The sound is coming from lower down in the cam area I think and starts a minute or so after the car is started. I know its not a great sound file but any help appreciated.
The engine is a ZC DOHC
