As an economy measure, a preliminary water test isgiven the cylinder block at this point. This is done on ajig which seals all of the water holes and allows the appli-cation of a 60-lb. hydraulic pressure. Only relatively fewoperations have been taken up to this point and leaks canbe detected at a time when it is not expensive to salvagethe block. This is only a preliminary water test, of course,as a later test is necessary after other cuts have been made.
