Nissan Teana sedan exhaust pipe to choose the blue smoke

A mileage of about 50,000 km, Engine product VQ23DE 2006 Nissan Teana 2.3L sedan. Vehicle motor exhaust to acquire the car diagnsotic toolblue smoke, flame parked more than about 3 min then with the auto after a high-speed motor vehicle, specifically potent smoke; parked in situ vehicle 10min, blue smoke slowed. Hard acceleration, the engine blue smoke and never velocity is amplified right away thicken.

Fault diagnosis: Following commissioning observation, fault phenomenon is in step with the above-mentioned phenomenon, but simply because Lanyan specially sturdy, and in some cases some white and exhaust choose the blue smoke considerably products only to find, you'll be able to identify a sizable range of oil in to the cylinder combustion.

Under ordinary situations, the engine burning oil is ECU programmermainly brought on from the next reasons: (1) piston ring use far too much oil, bond; ???¨¬|??¡§?2 valve stem seals getting older, dress in or harm; oil excellent is bad or perhaps the engine temperature is simply too substantial to make sure that the oil viscosity is just too low ; ???¨¬|??¡§?1 the crankcase exhaust too much, an excessive amount of stress, abnormal crankcase ventilation program, to make sure that the oil to the consumption manifold. So I check over a case-by-case basis in accordance to this line of thinking.

First look at the motor functioning situations: idle and accelerate the procedure efficiency of usual, the coolant temperature is taken care of while in the regular range, the right degree of oil. It reflects the proprietor, the vehicle just changed the oil a number of days later on, the oil high-quality confirmed, and that means you can rule out the 3rd reason.

Symptoms the final piston ring have on and tear brought on by burning oil: much less cold auto, consider the blue smoke, the engine temperature increases, the blue smoke will likely be extra and even more, especially the discharge of blue smoke when really hard acceleration is kind of obvious. This doesn't match milleage correction toolthe car's fault phenomenon, along with the car or truck was touring under fifty 000 km, not lost lubrication, piston rings should not be so brief to put on. It might exclude the first explanation for the malfunction.
