Disadvantages of the Honda H23A engine

  • The only serious drawback of these power units is the oil burner;
  • Oil not only goes to waste, but also likes to ooze from all gaskets and seals;
  • The cooling system also suffers from leaks, rubber tubes often burst here;
  • From time to time, sensor failures occur here and the engine starts to become very dull;
  • There are no hydraulic lifters and valve clearances need to be adjusted every 40,000 km.
