If it is a 1.6 Duratec Petrol engine it has solid valve tappets and not hydraulic ones. This type of engine is known to be quite noisy after a cold start.

The valve lash of this type of engine is adjusted by changing the complete valve tappets which are available in about 25 different sizes. The valve lash needs to be checked (and adjusted if needed) every 100.000 Miles (same interval as the timing belt). To change the valve tappets it is necessary to remove the timing belt and camshafts.
