not too fast but around 60mph giving it good amount of gas
177K miles, oil change about 1k miles ago

just recently clean up my throttle body, took off coilpacks to examine another issue im working on (oil, getting valve cover gasket fixed soon), thats about it for stuff ive done recently.

This is the first time I've heard this noise, and its very concerning.

This is not my video, but the exact same noise:

this is my video but it says it expires in 2 days so here:

Evap vent valve right by the back of the intake manifold. Disconnect it and it will go away.
Replacement should quiet it. I live with my noise

 

as long as im not throwing codes, Ill probably live with it. I will put this in the notes of "could bes"

others said the vvel actuator or lifters

Once I turned the car off and turned it back on the noise went away, very odd

 

You can confirm by disconnecting the evap, It will throw a code, noise will go away and you'll confirm is the valve.
Erase the code and start looking for a valve. If the noise comes back you might have a evap pressure problem.
Evap pressures are accumulating too much in the canister and are only released after they surpass the average release of these.

 

I have had this exact same noise for years coming from the rear of the intake manifold, but in the last couple days its become louder. The single digit temps might have something to do with the increase in noise.

By disconnect, I assume you are referring to the electrical connector on the top of the valve/solenoid? Assuming that is my problem, anything special I need to know when replacing other than remove the old and bolt in/connect the new one?
