The Nissan LD28 is a 2,753 cc, inline‑six naturally aspirated diesel engine produced between 1979 and 1986. It features a cast iron block and head, single overhead camshaft (SOHC), and indirect injection via a Bosch mechanical injection pump. This robust engine was designed for durability and torque in Nissan's commercial and passenger vehicles.

Production years 1979–1986 meet applicable Japanese and European emissions standards for their respective model years (VCA UK Type Approval data for imported models).
The Nissan LD28 is a 2,753 cc inline‑six naturally aspirated diesel engine engineered for vans, pickups, and passenger cars (1979-1986). It combines a durable cast iron construction with a simple SOHC valvetrain and indirect fuel injection to deliver strong, reliable torque. Designed to meet the emissions standards of its era, it prioritizes mechanical simplicity and serviceability over refinement.

The Nissan LD28 was used across Nissan's C230/S130/160 platforms with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts for the Patrol and different accessory brackets for the 280ZX-creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
The LD28's primary reliability risk is cylinder head and head gasket failure, with elevated incidence in engines subjected to heavy loads or poor cooling system maintenance. Nissan workshop data indicates this is a frequent cause of coolant loss and overheating in neglected engines, while owner reports often cite injector pump issues as a secondary concern. Infrequent coolant changes and overheating events make adherence to the factory service schedule critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The LD28 is renowned for its rugged mechanical construction and can easily surpass 300,000 km with proper care. Its main weakness is the cylinder head, which is susceptible to cracking if the engine is allowed to overheat. Neglecting cooling system maintenance is the primary cause of premature failure.
The most frequent issues are cylinder head and head gasket failures (often due to overheating), Bosch injection pump wear leading to poor running, and the need for periodic valve clearance adjustments. Cooling system leaks from aging hoses and the water pump are also common as the engine ages.
The LD28 was primarily used in the Nissan Vanette (C230), the Datsun 280ZX (S130), and the Nissan Patrol (160). It was a versatile engine, powering everything from commercial vans to sports coupes and off-road SUVs during the early 1980s.
Yes, but gains are modest and risky. Popular upgrades include adjusting the injection pump for more fuel and installing a free-flow exhaust. Significant power increases usually require adding a turbocharger, which is complex and can overstress the stock internals, particularly the head and head gasket.
Fuel economy is moderate for a diesel of its size. Expect around 9.0–11.0 L/100km (31–26 mpg UK) in combined driving for a typical Vanette or Patrol. Economy is highly dependent on vehicle weight, driving style, and the condition of the injection pump.
No. The LD28 is a non-interference engine. If the timing chain fails or skips, the pistons will not contact the valves. This design makes it much more forgiving of timing component failures, though a broken chain will still leave you stranded.
Nissan recommends SAE 15W-40 mineral diesel oil. This heavy-duty oil is necessary to handle the engine's high compression and thermal loads. Changing the oil and filter every 5,000–7,500 km is crucial for longevity, especially under heavy use.
