The 5.6-liter V8 engine Nissan VK56DE was produced at factories in the USA from 2003 to 2015 and installed in the largest and most powerful models such as Armada, Titan, and Infiniti QX56. In 2007, this engine underwent significant modernization, which is why there are two generations of this engine. The VK family also includes engines: VK45DE, VK45DD, VK50VE, and VK56VD.

The weight of the VK56DE engine is 240 kg (excluding attachments). The VK56DE engine number is located between the cylinder heads. The most well-known issue with this engine is the formation of scratches in the cylinders due to the entry of catalyst crumbs, which deteriorate from poor fuel quality. The symptoms include the appearance of a diesel sound during engine operation and oil consumption. Another issue with this engine is the stretching of the timing chains. Often, they become loose at around 100-150 thousand km of mileage, resulting in unstable and noisy engine performance. Replacing the timing chains can be quite expensive as it requires disassembling the entire front part of the car. It is highly recommended to closely monitor the condition of the engine cooling system as this engine tends to overheat quickly, leading to blown gaskets or a damaged cylinder head. This problem is exacerbated by the presence of an unreliable fan viscous coupling. Other common issues reported on automotive forums include difficulties in starting the engine during winter, lambda sensors that are sensitive to fuel quality, and an unreliable fuel pump. Additionally, do not forget about regularly adjusting the valve clearance, as there are no hydraulic compensators in this engine.
