Venting or recirculating bov?

[Agll30]

Hi I've been trying to figure out if my blitz bov is venting or recirculating. I've searched and found a couple but I'm still confused, so I figured I ask, that way I'm not guessing if it's venting or recirculating. Previous owner also blocked off a hose from the intake, that I think connects to the bov, but I'm not sure.

That is venting.

I trust you understand the consequences of such?

Oh okay. I've read that venting instead of recirculating could cause me to run really rich, which the stock maf will measure unmetered air. Could this cause my car to have high Hydrocarbon levels? I failed smog yesterday cause of high Hc.

You will run rich when shifting but only when the boost is past the "0" mark. Otherwise, the bov will not open, it has no pressure differential. The bigger worry is that you have a leak or its not set properly and you start either A: sucking air when idling or cruising or B: blowing air out while in boost.
A results in a lean condition while B results in a rich condition
This ONLY applies if the bov is worn out or misadjusted otherwise you can run vented and the consequence is a very momentary rich condition between shifts, again, only while in boost.

having said all that I always recommend to recirc if you can. If its not possible then so be it.

To answer about the smog test, yes, i think it could very well fail you.

Alright I appreciate the info!! I prefer to recirculate, than to suffer performance. Is there a way I can recirculate the blitz bov I have? Will a 1g bov work with my piping, it's a greddy uicp I believe.

First you'll need a recirculate adapter. They make them. Basically you unbolt the outlet and replace it with one that has a little flanged pipe piece on it. Then, unbolt your BOV and flip it around the other way so it faces forward. Then, pop that plug out of your recirculate pipe and put it on the BOV and clamp it down.

I've researched and couldn't find a blitz bov recirculating, some people eve said they don't make a blitz bov or recirculating only venting. Will a 1g or evo 9 bov fit on mine with a greddy uicp I have? Will I need a flange to bolt it on? Previous owner didn't care for this car.

That looks like a 1g BOV flange on your pipe.

So will the 1g bov bolt on with no further modifications to the uicp? Does mitsu sell the gasket for the 1g bov?

If it is indeed a 1g flange, than yes you shouldn't need any modifications. Also, yes on the gasket. http://www.extremepsi.com/store/product.php?productid=17635&cat=0&page=1
