Disadvantages of the B4204T35 engine

  • Most owner complaints on specialized forums are related to oil consumption;
  • In the early years of production, there were many cases of cracking of rubber pipes;
  • Once every 60,000 km, the fuel injectors must be washed or they will fail;
  • Change the timing belt every 120,000 km, as when it breaks, the valves bend here;
  • Another common problem with these engines is oil seal leaks.
