Turtlekid95 welcome to the noise haters club haha
Same noise ofc. Sounds VERY loud on your video - I can't usually hear it without having any obstacle/wall on the side that allows the sound to bounce back to me.
136k miles that's a good mark for that engine. Have you had any problems (rebuilds) yet?
BTW on russian forums they say that almost every N55 with decent mileage (smth like 50k+) does have this noise: some are quieter, some louder but most of them do have it.
