This noise started a couple of days back and only seems to happen on cold start for the first 30 secs and then dies down when the rpm's drop at idle. 
 
I will post another video soonish from the bay when on a cold start as it will be clearer - I know this one isn't the best from inside the cabin, was in a bit of a rush. 
 
That being said you can hear a kind of knock/tapping still. Timing Chain/Tensioner? Something else loose? Not sure. 
 
I know my gearbox mount is creaking alot possibly knocking? - Powerflex Insert getting installed very soon. 
 
The noise is much more pronounced when not driven for say a couple of days. 
 
Thanks.
