Thevalve-in-head type with tappet rods extending up one sideof the engine resisted longest the general tendency to en-close all working parts, but finally the hour of the exposedlong tappet rod has struck too. In certain engines, suchas the Weidely, the tappet rods extend up through a cham-ber whose walls are cast integral with the cylinder blockwhich gives generally the neatest construction, but mostdesigners cannot convince themselves that the very
