It could be a sticky lifter that isn't pumping up and closing the clearance between the rocker arm so there's a ticking.
It's hard to diagnose engine noises when you've got so little to go on and it's over the internet. Does it go away after some driving, or does it start making noise after you drive?
Thanks for the reply. Initially it did go away after imidiate start up them come back when it had warmed up. Now it seems to be there all the time but not so prominant until it gets warm. Your right its hard to diagnose engine noise over the internet, its also quite hard to discribe. The noise is sound like click, click then its silent for a few seconds then click, click, click then silent for a few seconds then click and so on. It does seem to be getting worse though.
When you are driving you can hear it at low revs, when you accelerate it sound a bit like pinking.
However the engine does seem to run a bit smoother after the new waterpump.
