Disadvantages of the Renault V4U engine

  • This unit does not tolerate bad fuel and operation with faulty spark plugs.
  • Because of this, catalysts are quickly destroyed, and their crumbs lift up the engine cylinders.
  • It often squeezes out paper oil channel gaskets under the front cover.
  • The timing chain does not differ in resource either, it is often replaced already by 200,000 km of run.
  • Also, the motor is very afraid of overheating, and the water pump does not last very long here.
