Disadvantages of the B6304T2 engine
On the forum, owners of vehicles with such a unit most frequently talk about oil consumption;
Grease frequently seeps from beneath the vacuum pump or around the timing chain cover;
There is typically a whistle under the hood when the oil separator fails.
The generator was flooded during the initial years of engine production due to a leak in the front cooling tube;
A block of a pump and power steering that is mounted on the same shaft is another weakness in the motor.
