Masservy impressed us with the cost of servicing the present standard tappets. Naturally the introduction of hydraulic tappet operation is a costly business. To obtain an idea as to whether it is worth bringing it in, we should like to have some indication of how much you spend annually on servicing Phantom tappets and valve gear for noise.
