Disadvantages of the ENC engine
The distinct cylinder heads in this diesel frequently crack;
Additionally, they must be stretched on a regular basis to prevent significant lubricant leaks;
The turbine is notoriously unreliable; occasionally, it can drive oil up to 100,000 kilometers;
Although they are expensive, the hoses that go to the turbine and intercooler are frequently frayed;
They continue to complain about vibrations and noise at work on the forum.
