I've done the valve clearances, but can't seem to quieten it down

Anyone got any ideas?

Can't remember to be honest, it is due an oil change though, just not got round to it yet with this weather

Assuming the valve clearances are set correctly it could very well be worn/tired LMAs. Always very difficult to diagnose noises from videos though due to distortion and mic levels picking up background noise rather than the main one we're interested in... for example I can hear the injectors ticking away quite clearly in this vid

It's the ticking noise I'm referring too

Like I said, it's difficult to pinpoint noises from a video clip as it's just a noise with no "direction of origin" as such.
The injectors I can hear but I can also hear a slightly heavier tapping which could be worn/tired LMA(s) or still a loose clearance.
With noise diagnosis most of the time you need to be there and get amongst the noises to pinpoint a direction of origin. Things can then progress further as you know where to look for worn/loose items
