TOYOTA LANDCRUISER 4.2 1HZ ENGINE – JEG Auto

The 1HZ is a 4.2-liter, naturally aspirated inline-six diesel engine. Because it lacks a turbocharger, it operates under lower internal pressures, which is the secret to its incredible longevity. It isn’t uncommon to see these engines clocking over 500,000 kilometers without needing a major overhaul.
