be taken out either at the top or l the bottom. but in other engines | the lower end of the rod is too big to go through. A properly fitted pearlng must not be so tight that ehe fod or shaft cannot be turned, out al at the same time it must fit suhsy; This condition will be in uIealed by the distribution of black epols all over. the bearing surface aAeer the iampblaek and oil test. NeAt the wise car owner will give the olllng system some attention. In the case of a plain splash system the lower half of the crankcase snould De mopped out with a cloth alter the. old oil has been drained out opVlously. If the fabrication system embodies pipes and screens. kerosene should be forced through the plplng and the screens should De taken out and cleansed of any iorelsh matter found in them.
 u may be that the piston rings will neeu renewal. or the cylinders may ue scored This latter condition. if 'iie scoring IS serious, calls for re- grinding or for reboring, according to the circumstances. If it is rebor;ng have all the cylinders done rather than just one
 This is good time to go over rho valve system. The valves shouId hc removed and carefully ground. While they are out inspect them for warned heads and worn stems. Each valve should be fitted in it's guide and if mere IS too much play, a pushing should be installed in the guide ar else new valve with an oversize stem.
 Clean Cooling System
 The cooling system will need good cleaning out. In case the ear owner has reason to believe that his cooling system is exceedingly dirty. ne might well pass the radiator over 10 the service station and have the accumulation of dirt boiled ont of it. Overheating difficulties often re- suit simply from an accumulation of foreign matter in the radiator. The rubber hose connections will prob- ably need renewal: unless they are absolutely sound inside they should certainly be replaced If a water pump is used, the packing nut ought to be removed and the packine re. newed. Incidentally in replacing the nut, do not screw it down too hard
 The ignition system will undoubt edly call for considerable attention. All terminals should be cleaned in | sulaton breaks be taped, connections frightened and loose wires fastened | down so that they will not swing or touch hot metal. It is a good plan | to run all the wires in conduits. if | this has not already been done. The | ignition unit should be given a | thorough cleaning and the points be trimmed flat.
 Electrical Apparatus
 The starting and lighting system will need only minor attentions. The bearings in the starting motor and | generator should be given proper lu- brication. If silent chains are used | they ought to be cleaned and thor oughly fabricated. All chain slack 1 should be taken up and this applies, to cars having timing gears caain driven.
 The fan assembly may need a tightening up and the clutch will certainly want a little attention which will depend on what shape it is in. All connections and bearings in the clutch assembly should be fabricated copiously. The transmits sion bearings may need replacement or taking up and this generally rather than the owner.
 A general tightening up of all the various mechanical and chassis units is advised. If the chassis includes torque members, these will
