Disadvantages of the ENC engine

  • In addition, they need to be stretched periodically or serious lubricant leaks will appear;
  • The turbine is distinguished by low reliability, sometimes it drives oil even up to 100,000 km;
  • The hoses leading to the turbine and intercooler are often frayed, but they are not cheap;
  • Still on the forum they complain about noise and vibrations at work.
