VQ35DE 3.5L V6 Engine Problems

VQ35DE 3.5L V6 Problems And Reliability

Based on various owner reviews and our opinions, for a better understanding of these engine problems, we have compiled a list of the most common problems that are often encountered in the use of Japanese engines. Nissan VQ35DE 3.5 liter volume series.

  • Increased engine oil consumption. In general, the engine in question is very reliable, but after long usage (after 200 thousand kilometers) and oil (more than 600 grams of oil per 1000 kilometers), one of the causes of oil burning in the VQ35DE engine is coking, which is associated with long driving at low speeds (often during traffic jams) or in bad weather, because contact products from the catalytic converter slowly degenerate into the work area of ​​the cylinder.
  • Engine oil leak. Lubrication leaks in the engine being monitored occur because of a cardboard gasket oil line located under the front valve cover. Over time, it is from under the front cover that the oil is squeezed, as a result, pressure on the internal combustion engine begins to fall and various errors arise in the phase regulator. According to experts, if you do not pay attention to oil leakage, then the level of lubricant in the system will decrease and may only reach a tipping point, which will cause the power plant to dry out.
  • Excess heat from the 5th and 6th cylinders. As we said before, Nissan engines are quite reliable, but the cooling system inside has disadvantages, which is why cylinders 5 and 6 are the most vulnerable to overheating. Often overheating results in the fact that the valve cover closes dry and oil penetrates into the spark plug hole. As a reference, many car owners independently complete their engine cooling system, which allows them to function properly forever.
  • Minor damage. To various other weak points of the power plant, experts often connect thick, unreliable couplings from cooling fans (on average, service life is 150-180 thousand kilometers). In addition, due to the lack of a hydraulic compensator in an internal combustion engine, the valve must be adjusted from time to time, which does not provide much pleasure for the car owner.
  • Before you consider the VQ35DE engine features, a few words must be said that this power unit is very popular with other car makers, so it was also installed on their car models from Renault (Latitude / Espace / Vel Satis) and Samsung (SM7) EX2 / SM7 L47) below the V4Y factory index. So, as we mentioned before, Nissan’s most famous 6-cylinder “V” engine – Infinity debuted in mid-2000 with Nissan Murano SUV and sports coupe Z350.
  • This Nissan VQ35DE engine has an unusual design, which is not a characteristic of making Japanese engines in the early 2000s. The VQ35DE Series 3.5 liter engine is equipped with an aluminum cylinder block, 2 DOHC (Double OverHead Camshaft) heads and a time chain drive. On the power intake camshaft unit, the CVTCS variable valve timing mechanism is installed.
  • The highlight of this engine is the nylon manifold, the forged connecting rod and the crankshaft, and the piston which is coated with a layer of molybdenum. In addition, all engine scrubbing components must have special maintenance. As for hydraulic lifts, they are not provided for this engine by the manufacturer, so all 24 valves must be adjusted periodically.
  • The manufacturer claims the engine life is 300,000 km, but it is easy to run 400,000 km.

VQ35DE 3.5L V6 Engine Modification

In August 2006, an improved modification was released: the VQ35HR engine, which has a similar aluminum block, two DOHC heads without a hydraulic compensator, timing chain and CVTCS to change the gas distribution phase.

Unlike the VQ35DE, here the beam is 8 mm higher, the neck and crankshaft linings are stronger, the 144 mm connecting rod is extended to 152 mm, the asymmetry of the skirt is added to the piston, and the compression ratio is increased from 10.3 to 10.6 .

Phasoregulators are now in the inlet and outlet, layers like DLC diamonds on camshafts and cam followers reduce friction by 40%. Refrigeration reconstruction solves the 5 and 6 cylinder overheating problems.

VQ35DE 3.5L V6 Service

Power backup and load resistance characterize the VQ35DE engine as a reliable power unit.

  • The claimed timing resources are unlimited, in practice requiring maintenance costs with a range of 200-250 thousand km, when the circuit is broken, the valve is pressed.
  • Every 15 thousand km (if you drive actively, change oil every 7-8 thousand), you must change the oil to a new one with a viscosity of 5W-30 or 5W-40, with a volume of around 4.7 liters.
  • It is recommended to replace antifreeze every 90 thousand km or every 5 years. Pay attention to the cooling system, clean the radiator from dirt every two years.
  • Every 30,000 km, regulations require that wax be replaced.
  • To adjust the VQ35DE valve, which is desired every 100 thousand kilometers.

VQ35DE 3.5L V6 Enigine Tuning

  • The initial way to improve the VQ35DE engine is to do chip tuning, which adds 10 hp. But this is too small and irrational, because this engine has strong potential.
  • In the first case, false piston and connecting rod bolts, enlarged valves, camshafts with phase 272/272, nozzles with a capacity of 440 cm³ / min, forward flow and new firmware are installed. The price of such an upgrade leads to the second tuning option – installing turbines.
  • To do this, change the connecting rod and piston group. Put the nozzles on the 600cc, make a ported head unit and, of course, add a 0.4 bar supercharged compressor.
  • There is also a ready-made turbo kit for VQ35DE, which easily increases power to 400-500 horses. Even 1000 hp isn’t the limit for this machine, but the unit is involved in a fundamental upgrade.

So the above conclusion, we note that the Nissan VQ35DE 3.5 V6 petrol engine, made by Japanese experts, is quite feasible in reference to a very reliable power plant, regarding power output for general maintenance. The 3.5 liter VQ35DE series engine is the main reference of the “VQ-series” engine, thanks to the electric units from this family which are famous and popular all over the world.

The resources of the 6-cylinder engine, which was developed from scratch by Nissan engineers, according to guarantees from Nissan’s manufacturers, are about 300,000-350,000 kilometers for repairs. However, often in reality, the life of a strong Japanese person often reaches 400,000-450,000 kilometers before replacement.

Thus, the life expectancy of every modern gasoline engine is directly dependent on the competent operation of the car by the owner, the quality of the fuel poured and compliance with engine maintenance regulations in terms of frequency of updating major consumables with technical fluids (original lubricants that are in accordance with manufacturer tolerances ).


  1. I owned this engine in the Renault Espace IV. He made Espace a fantastic vehicle. Knowing that most of the Espace are powered by diesel that does not develop more than 170 hp.
    The engine was running on E85 (much cheaper than gasoline in France). I sold it with 270,000 km and the new owner is still happy with it
