Disadvantages of the B6304T2 engine

  • Owners of cars with such a unit on the forum most often discuss oil consumption;
  • Often, grease oozes around the timing chain cover or from under the vacuum pump;
  • The failure of the oil separator here is usually accompanied by a whistle under the hood;
  • The first years of engine production, the front cooling tube leaked and flooded the generator;
  • Another weak point of the motor is a block of a pump and power steering, sitting on the same shaft.
