Very annoying ticking noise!!??

....seems to be from left of engine as you look into bay, frequency varies with revs and seems to dissapear at 2/3K revs (could just be engine noise drowns it out) reminds me of Beetle timing chain/tappet sound?

Realise that online diagnosis tricky but any ideas?

Thanks

Thanks Paul, just spoke to Peter Tognola who also thinks it's probably tappets!

Just went for 1 hour drive and it self-corrected. Stopped in at AFN Chiswick for a cake, coffee and a confirmation of our diagnosis....all very civilised - but £100/hour labour is very un-civilised IMHO!
