The Care of the Car PISTON RING LEAKS Sometimes when an engine is taken down it is found that the slots in the piston rings are in line, the rings having gradually worked round into this position. In the case with rings with slanted slots, the trouble can be overcome by making certain that the slots are at a different angle in succeeding rings. That is, if the slot in the top ring slants from left to right, see that the slot on the next ring is from right to left. RADIATOR OVERFLOW Should the radiator cap leak constantly and excessively, and you know that the washer is not chewed up, run a wire through the overflow pipe. Possibly it is clogged, and there is no outlet for the water except round the radiator cap or neck. RING GEAR CAUSES “MISS.” A number of mechanics had diagnosed the trouble as a miss and the engine had been vainly tuned up several times in an effort to remedy the trouble. After thorough testing it was found that the trouble was due to a warped ring gear, and a new gear remedied the difficulty. KEEPING SPARK ADVANCED Some drivers will have observed that there are certain types of manual spark control which work concentrically with the steering pillar, and which, in some instances, have a tendency to work back to the “retard” position unless watched carefully. If the magneto or battery distributor control lever is accessibly placed, it is a simple matter to attach a light spring in such a way that the. movable part of the ignition is always held at “advance” unless the hand lever is operated. A BEARING SQUEAK The engine in the demonstrator developed a fleeting groan, which was heard just as the engine came to a stop after the ignition was turned off. The oil pan was removed and the engine started with a mechanic under the car. The noise seemed to come from the centre crankshaft bearing, and inspection of this bearing showed some marks. It was dressed up, and the noise was cured.
