replace the hydraulic tappets in the rocker arms, valves are non adjustable.
to adjust the rocker arms you have to either tighten or loosen the top bolt on the rocker arm/arms that need to be adjusted. there is a specified torque for the rocker arms that you should follow to help you adjust the them
Check that it has adjusters on the rocker arms, as Lombardini have switched to hydraulic tappets on most of these engines. If yours has adjusters, the manual can be downloaded from their website. Cheers, John Higgie

It has hydraulic lifters, no adjustment. If you have valve noise you probably have worn valve train parts. Replacement of worn parts would be required.
