I had to correct a fair amount of spelling errors but does the above apply and help any F50 Q45 owners?http://en.wakopedia.org/wiki/Nissan_VK_engine wrote:Warning to all those who own this engine** All VK45de engine consume oil. The PCV-positive crank case ventilation passages in the valve covers are not designed correctly and flow too much, thus allowing large amounts of oil into the intake system. This will cause puffs of blue and white smoke after cold starts! In lack of attention this condition will cause low oil level, which in turn results in worn cylinder rings causing excessive blow-by gases. The engine will eventually develop low compression in the rear most cylinders first. To easily confirm this condition- remove the intake duct from the throttle chamber and open the throttle flap manually. Large amounts of oil residue will be seen, as well as oil pooling in the back of the intake manifold plenum... Nissan and Infiniti are not stepping up to the plate although this is a know issue. They are putting the blame on the customers lack of service. Record all service data and present your case to a dealer. Under proper service the engine will be replace under full warranty it the vehicle is within the time and mileage limit...
