This noise just started happening as far as I can tell. I'm usually pretty aware of 'weird' noises. It goes away when I turn off the engine and turn it back on. But it comes back if I go out driving and let it idle.

Does this sound like anything to anyone?

That noise is classic NOISE FROM BANK 2 VVEL ACTUATOR...been there, done that!

If you want it to go away have dealer perform TSB #ITB08-028a and start using Nissan ester oil.

If you don't, just put up with the noise; like you said, if you stop and restart the engine it goes away (it resets the VVEL timing angle).

 

I had exactly the same noise , but after i install the engine oil cooler i did not notice it anymore.

 

What they said... Nissan ester oil is the answer = $$

 

Thanks for narrowing this down

I wouldn't say mine sounds that bad yet. Linking it because there's a few other threads with dead videos, which led me to post this in the first place because I had nothing to compare it to.
