My 2002 Ford Mondeo is producing a tapping noise - can you help me fix it?

I have a Ford Mondeo Ghia TDCI 2002. It has a tapping noise which is very loud when I start the car. When driving over 1000rpm it goes way. Can you help me fix it?

This could be the hydraulic tappets. When the engine starts, oil then builds up pressure and that's why the noise disappears. Happens on quite a lot of engines.

The tappets are noisy on my 1.8 Vauxhall Astra. It was overfilled with oil by the old owner so I drained it and put in new then added hydrolic flush but there was no change?
I have an Alfa 156 which was running sweet except a bit tappy on cold start up. The noise lasts about 10 secs then is fine. I have replaced the cambelt as the car had 55,000 on the clock and nobody could...
