The weight of the VQ25DE engine according to the catalog is 185 kg. The engine number for VQ25DE is located at the junction of the block and the gearbox. The main problem is caused by catalyst crumbs entering the combustion chamber. Excessive oil consumption of more than 1 liter per 1000 km suggests the presence of cylinder scoring. The engine is prone to overheating, which quickly damages the mating surfaces. After 200,000 km of mileage, the timing chain often stretches and starts making noise. The culprit of fluctuating revs is often contamination of the idle air control valve. Oil leaks can occur from under the valve cover and from the camshaft position sensors.
