Disadvantages of the Mazda AJ-DE engine
- This unit is famous for its high reliability, but also for its impressive fuel consumption;
- Monitor the condition of the mesh in the tank or your fuel pump will quickly fail;
- The water pump serves relatively little here, and radiators also regularly flow;
- Often there are lubricant leaks in the area of the oil pan and from under the cylinder head covers;
- After 200,000 km, oil consumption often appears due to the occurrence of piston rings.
