  • Problems with the fuel system are often discussed at specialized forums: injection pump and injectors;
  • Saving on lubrication often leads to the replacement of a turbine or hydraulic lifters;
  • Monitor the condition of the timing belt, with its breakage, the valves bend and the camshaft breaks;
  • Here is a dual-mass flywheel and when it is worn, the crankshaft pulley quickly breaks.
