Hi , I have a 2002 Nissan Sentra ser , this car is equipped with a qr25de engine , the piston rings came defective from factory , Nissan doesn't assume their responsibility , but they sell improve piston rings for this type of engine . . . Engine oil disappear with stock piston rings, car doesn't have any leak . . . . Machine shops know this problem . . . Consequence of this matter is that people brakes connecting rods , cylinders have uneven waste . . . Nissan only give 60k miles warranty on power train , but before that I notify them about this problem , they said that "was cylinder head". My point is the next: " if there is not any problem with the stock piston rings why they sell improved piston rings? " . . . . They know that are a problem with the stock piston rings. . . . Thank you.
