Nissan VQ35DE Engine Problems and Reliability
1. High oil consumption. Catalysts of the VQ35DE are very sensitive to fuel quality. They produce ceramic dust, which damages the cylinders and piston rings. As a result, the engine has low compression, high fuel and oil consumption, and other dead engine symptoms. 2. Engine overheating. That is not a typical problem, but it has a place to be. Check the radiator condition and expansion tanks of the cooling system for any leaks.
