I posted this question in another thread. Rather than start a new thread, I thought I might also post it here.

How active should the BOV be? Lately I hear my BOV a lot. Like every couple minutes while driving on the expressway.

Are running with the OEM BOV? I don’t hear a thing. Last week I heard rumbling noise during acceleration, turned it was due to me took out the resonator. I put it back in, the noise is gone.

Pretty sure it’s stock. At least I can say with certainty that I haven’t changed it. The prior owner did change the turbo so I guess there’s a chance it could have been swapped out.
