I thought I'd read somewehere that the valves were hydraulic, so no need to adjust.

You are probably right, it was this thread from last year which I had read.

There seems to be some confusion as to whether they are hydraulic or not.
Need someone with a workshop manual to confirm.

Per the WLT Engine Manual CD, the clearances are (cold engine):-
Inlet 0.05 - 0.15mm
Exhaust 0.15 - 0.25mm
Don't know why there is such a large range in the clearances

odd I thought there were hydraulic on the diesel, oh well if not a lot less to go wrong!
THen question comes, if they are manual adjusters, are they adjusters or shims......

Franco says, 'Don't know why there is such a large range in the clearances' - the exhaust valve gets hotter therefore expands more.

It lets HOT gasses out, the inlet valve lets COLD air in.

Didn't mean that vanmanerik - I wondered why each valve had a margin. In the old days, the gap always seemed to be a set measurement i.e. 8 thou.
As you say, exhaust valves have always had a larger gap due to the heat.

Now if the topic was in thous, instead of this metric nonsense I would have understood the question.

I can 'feel' to a couple of thou but what is 0.15mm - might as well be green cheese!
