Turn the pcv valve about a half turn counter clockwise and it comes out . I used a little black silicone on mine to seal it up all nice .

Any possible way to get this on video or is it too quiet? I'm going to try to get mine on video but I don't think the mic will pick it up over the wind noise .

Sub'd. I have something kind of similar going on. Makes a rotational squeaking noise only while accelerating, just at the top of the gears before it shifts. Let off the gas, and it stops. Kind of similar to when the planetary gears tore themselves to bits in my trans, but this is definitely coming from the engine compartment, not the transmission.

Well I figured mine out! I took the belt off to replace my idler pulley on the a/c side and I randomly spun my alternator . Sure s*** it whistled when I spun it . It's at the dealer right now hopefully getting replaced . I'm tired of hearing ( it's normal) from them.

Mine went away a few weeks ago on its own. It still bugs the crap out of me not knowing what it was.

There is an o-ring on the engine oil dipstick, if this is bad or missing, it can make an annoying whistle, especially when cold.
