Nissan's VK5.6DE 8-liter V56 engine was produced in US factories from 2003 to 2015 and was installed in the largest and most powerful models, such as Armada, Titan, and Infiniti QX56. In 2007, this unit was seriously upgraded and therefore two generations of it are distinguished.
The VK family also includes internal combustion engines: VK45DE, VK45DD, VK50VE and VK56VD.

Description devices motor VK56DE 5.6 liters
In 2003, a larger and more powerful version of the 4.5-liter VK45DE engine debuted. By its design, this is a similar V-shaped eight with a 90 ° cylinder camber angle, an aluminum block with cast-iron liners, two DOHC heads without hydraulic compensators, a multiport fuel injection system, an electronic throttle and a timing chain drive. With the 2007 update, the unit received CVTCS phase shifters on the intake camshafts.

Disadvantages, breakdowns and problems of the VK56DE engine
The most famous problem of this unit is the formation of scoring in the cylinders due to the ingress of crumbs from the catalyst, which is destroyed by bad fuel. A symptom is the appearance of a diesel sound in the operation of the engine, as well as oil consumption.
Timing chains are distinguished by a low resource in this engine, often they are already extended for 100 - 150 thousand kilometers, which is expressed in unstable and noisy operation of the internal combustion engine. Replacing chains is quite expensive, as it requires dismantling the entire front of the machine.
We advise you to carefully monitor the condition of the engine cooling system, as it quickly overheats and immediately breaks the gasket or leads to the cylinder head. This problem is exacerbated by the presence of not the most reliable viscous coupling for the fan.
In specialized forums, they often complain about the difficult start of the engine in the winter, lambda probes that are sensitive to the quality of gasoline, and also an unreliable fuel pump. Also, do not forget about adjusting the valve clearance, because there are no hydraulic lifters here.
The manufacturer declared the resource of the VK56DE engine at 200 km, but it serves up to 000 km.
