2.5 turbo diesel (in 1989 190) ticking noise

Just going to see a car again tomorrow and wondered if there is a way to tell if this is hydraulic tappet or chain tensioner shock absorber etc. I have heard a few of these engines with no 'tick' so this is not a normal sound

I have read up what I can so have some idea but symptoms are.

From cold, ticking over there is a tick at about 1 second intervals.
As it warms up this is the same (as I recall).
Revving the engine slowly, when parked, causes the speed (but not volume) of the tick to increase as well.

Any suggestions or advice welcome, engine pulls well, ticks over steadily and seems 100% apart from this.

A bit late for any advice now as bedtime here in sunny France so will be viewing the car before logging on again.
Any comments appreciated though as I don't (unless I think it is otherwise ok) intend to buy tomorrow, so still valuable info.
