Hey all, new here but wanted to know if this sound is normal or if I should have the dealer fix it while the car is still under warranty. The Altima only has 17,xxx miles on it and has made this noise for a while now I think. This video is not mine but sounds exactly like the noise I hear and says it may be the PCV valve. Thank you in advance!
