Valve clearances

Hi All.
Iíve got a 2001 156 Selespeed with 41,000 on the clock and itís got a bit of noise from the top of the engine.
Itís a kind of valve tapping sound that I reccon is a tad too loud, which made me think the valve clearances may need setting up. Can this be done on these or is it like the hydraulic un-adjustable ones.
Iíve used a long screwdriver with one end placed onto the injectors and the other on my ear to detect if it was them making the noise and Iím fairly sure it isnít.

All help appreciated.

Re: Valve clearances

They're hydraulic... Could be that the timing is out sightly....or they're running / have run a bit dry.

Has your timing belt been changed recently? It should have been done at 36,000 (or 3 years)....

A recording of the sound would be useful, if you can?

Re: Valve clearances

Cam variator.

Does the car sound like a diesel when it is first started up?
