Hi guys can someone explain to me how having a BOV vented to the atmosphere increases pollution? No not noise, that isn't the issue, unless it's over the DBA limit of course. The BOV only opens when the throttle is closed and when the throttle is closed the PCV valve draws air from the cam cover venting into the engine where it is combusted and cleaned by the cat.

So if everything is working OK, the only thing that comes out of the BOV is what went through the air filter. Since the air filter cleans out some crap, I would have thought the EPA would be happy with BOV's vented to atmosphere as they clean up the air for us to breath.

Try that next time the pesky pests annoy you.

Yeah but that assumes your engine and BOV are in perfect running order. I would imagine there would be a number of incidences where a sick engine/turbo can spew noxious gases out of the BOV. Also would a venting BOV make the engine run rich? Changing these circumstances would increase noxious emissions?

Hi Tony, a couple of comments following on from your last post.....

"assumes your engine and BOV are in perfect running order"

So the pesky pests should be checking badly running cars, not ones with atmosphere vented BOV's. I followed a car to work this monring that was spewing so bad I had tears in my eyes, had to put the A/C on recirc.

"Also would a venting BOV make the engine run rich"

Yep, but not as much as when the engine is cold. At least the cat will be warmed up when the BOV vents and do something about it. When the engine is rich and cold, so is the cat, so it don't do squat.

Hope that adds to the discussion.

Can you make all BOV's plumbback, or only specially designed ones?

i am not a riceboy but dont have a big adversion to the noise as long as it only comes on when boosting.

But i dont really want a atmo venting one as i couldnt be bothered with the hassle from the cops

yes i will be running large amounts of boost on occasion :D

    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
