Hey y’all, just noticed this ticking noise from the back of the engine on my 2010 G37 Coupe. Any ideas what it could be from & should I be worried? Is it lifter tick? Don't recall ever hearing it before but I just got back from some spirited driving when I heard it and recorded this video. Currently at 118k miles.

There are two noises in your video

One is common valvetrain noise
Second one is the Evap valve in the back of the intake manifold

@bread seems like another one with this same issue.

 

I didn’t even notice the valvetrain noise, what sound is that in the video (Assuming its not the ticking).
Should I be worried though about either? I have restarted the car times and it is still ticking I noticed @bread said he restarted his car and it went away. Checked the oil multiple times and oil looks good.
