Disadvantages of the DK5ATE engine

  • This diesel engine is considered quite capricious and, moreover, very difficult to repair;
  • His main problem is the cracking of the cylinder head from any overheating;
  • Non-original oil quickly affects the operation of the turbine and hydraulic lifters;
  • On runs over 300 thousand km, the prechambers can crack and fall out into the cylinders;
  • Most of the spare parts for this engine are unreasonably expensive and not common.
