1HZ 4.2L Diesel Bare Engine / Long Block – Toyota Replacement Engine
This 1HZ bare engine is a complete long block assembly built to OEM standards for Toyota vehicles. It is the legendary 4.2‑litre inline‑six naturally aspirated diesel engine known for its exceptional durability and simplicity. The assembly provides a factory‑fresh foundation for your engine swap or rebuild, saving you heavy downtime and expense compared to repairing a worn or seized diesel unit.

- Toyota Land Cruiser 70 Series (1990 – present, various body styles)
