WARNING!

OIL SMOKE WATCH THE BREATHER TUBE. Just because a car that is very economical on oil smokes through the breather tube of the crank case occasionally, there is no great reason for worry on the part of the driver, for there must always be a certain amount of burnt oil to give rise to this. It will be noticed that this smoke is at its worst when climbing a steep hill slowly, and most of it is caused by the friction of the connecting rod and crank shaft bearings on the thin film of oil between the journals and the bearing caps. | However, should the smoke become excessive, it is always a sign that the oil has become badly diluted with raw petrol from the combustion chambers, and the oil needs replacing. In the event of the smoke being as bad as ever, it may bo taken for granted that the pistons are badly worn, and that an excessive amount of petrol has entered the crank case, and the only remedy then is new piston rings and, perhaps, pistons. Captain Malcolm Campbell has just acquired one of the famous team of Delage racing cars which was so successful in 192 G and 1927, and may be expected to make his appearance on this car at Brooklands.
