Guys
Is there a rubber O ring for the BOV?

Yes there is but it's part of the BOV part from Toyota so you can't buy one. Best thing is to go to a seal shop and match it.

I just checked on eBay and I found it. Now I can use a universal O-ring.

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.

I have, currently, a stock/OEM bpv/bov - I can hear it. Mine is vented to atmosphere and is quite loud, actually.
I notice it's louder in cooler temps.

The noise would be annoying for me.
