What Does “Long Block” Mean?

A long block generally refers to the assembled engine core consisting of the main internal engine components and cylinder head. It is not necessarily a complete plug-and-play engine assembly.

External components may need to be transferred from the original engine, depending on what is included with the listing. These can include the turbocharger, intake and exhaust components, alternator, starter, air-conditioning compressor, power steering components, engine wiring, ECU, sensors, fuel-system components, and other accessories.

Please contact the seller or review the listing photographs to confirm exactly what is included.

Mileage

The engine has approximately 132,000 km.

Mileage should be considered together with the engine’s actual condition, service history, compression condition, oil pressure, and inspection results. Please review the available photographs and listing information carefully before purchase.

Installation & Engine Swap Information

Professional installation by a qualified technician is strongly recommended.

Before installing the engine, inspect or service appropriate components such as:

• Timing belt and related components
• Water pump
• Seals and gaskets
• Cooling system
• Oil system
• Turbocharger
• Engine mounts
• Clutch and flywheel
• Wiring and connectors
• Sensors
• Vacuum and boost hoses

When installing an AGU engine into another vehicle, additional compatibility work may be required depending on the original engine and vehicle configuration.

The ECU, immobilizer, wiring harness, sensors, transmission, and engine-management system should be checked for compatibility before completing an engine swap.
