I have a tapping noise coming from the cam cover, I belive it is a hydrolic tappet or follower that is causing the issue.

Can anyone advise whats the best way to fix this?

I thought all silver tops did this until they were warm/hot has it been run up properly if it hasnt I'd just leave it and see how it goes when its on the road.

What grade oil are you using ? anything other than 5w/30 can cause hydraulic tappet problems on silver top engines.
Even if you are already using 5w/30 a dosing with Wynns Hydraulic lifter treatment might clear it.

Im using 5w/20w its been running fine for a while but has just started doing it

In that case I'd treat it to a oil change and try the goo that BT recommends above, and run it until it dies and then change it for a black top when possible.

Had the same issue with mine til I changed to correct synthetic oil. Sounds fine now.

5w20 is a bit thin.

I run one of my silvertops for a couple of years on 10w/40 without tappet noises though I know you shouldn't. 140,000 mile engine as well. Low oil level makes em rattle though.

You need 5w30 in there mate. 20 is too thin so it will tap. I find zetecs seem to prefer fords own oil aswell they are funny with the wrong oil.
