Disadvantages of the M41D17 engine

  • This diesel engine is afraid of overheating, it causes cracks in the block head;
  • The turbine has a low resource, after 150,000 km it usually already drives oil;
  • Floating engine speeds and poor hot start hint at an early repair of the high-pressure fuel pump;
  • The EGR valve clogs pretty quickly and the engine starts to get very stupid from this;
  • The chain gas distribution mechanism may require replacement up to 200 thousand km.
