Engine Overview and Common Failures

The weight of the QQDB engine according to the catalog is 125 kg. The Ford QQDB engine number is located at the back, at the junction of the engine and gearbox. Owners of such engines are always struggling with fluctuating idle speed. Some are helped by reprogramming, while others by cleaning or modifying the throttle. Rapid catalyst wear often leads to its particles being drawn into the cylinders. The timing chain may need to be replaced at mileages of 200-250 thousand kilometers. Poor fuel quickly damages spark plugs, ignition coils, and the fuel pump. Oil in the spark plug wells suggests the need to replace the valve cover. Keep an eye on the lubrication level, as oil starvation can cause bearing damage.
