Disadvantages of the Mazda AJ-DE engine

  • 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.
