Going to work yesterday it sat at 4k for about 10 miles and when u slowed down again could here the tappits?( had the music on so wouldnt have heard them)
Anyways let it cool down ( 4 hours ) and drives home still chaping away!

Mine was tapping before the top end of the engine shat itself. When I took it apart I cleaned the tappets in a degreaser bin and it's totally fine now.

If it didn't used to tap, and now does. It's likely oil pressure related.
To be safe, buy and fit an oil pressure gauge.
To be abit safer, clean out the pressure relief valve.
To be durex safe; change the oil pump lol

Possible that the tappets are sticking again. I used to find that alot with the 1800 16v Vauxhall engine that even after a flush, strip and clean they would still stick. Some cases you would have to work them for a good few minutes each to free them off completely.
Rather than using old tappets, i would consider buying new ones, i think they are around £7 each

Have you actually checked to see if oil is getting to the head?
Run it and take the oil cap off. If there is plenty there it will start to splash out.

not an injector clicking?
you can actually put an oil pressure gauge into the head itself to see how much pressure is getting to the head(grub screw between 2/3 cylinders on ex side)
is it still a top end tap? if had a crack in the pike up pipe you could either of killed the lifters of maybe even have a bottom end knock

Mines started doing the same tonight
Revved it upto 5k and noticed a tapping when I let off. I got home and let it cool down. Started it up again after checking oil level, was getting 4 bar of pressure, Held revs at 3k and it cut out. Fired up again and got a bit of a chewing noise so crapped it and turned it off
Investigation to start tomorrow

Think I've found the cause of my tapping.
Checked compression and cylinder 3 is 0 Looks like i've dropped a valve.

eek you did well lol.
should have propperly cleaned the hydrolic lifters and the head in a hot de greaser bath would have got rid of any little bit of grit/metal filing's that can cause things to stick
