i was given a bov for free from my friend. it is a ebay xspower bov, i really dont know which model or whatever. but my question is on the top of the bov there the nipple is, isnt it suppose to be sealed and so tthat no air can get in or out or is it suppose to let a little air in/out?

 

ummm thats where the vac line goes

 

yeah i know but is it supposed to be sealed so that no air comes in/out or is it supposed to let a little air in/out. cause i really dont know if i should use this bov or not. and does anyone know what knock-off this bov is suppose to be?

 

ok.... it seems to me that you dont really know how a BOV works. I am not trying to be a dick or anything so dont get me wrong....

You have to put a vac line on the nipple and run that to your manifold or a Vac manifold.... there is a spring inside that along with the Vac line (that will also see pressure when you are in boost) keep it closed. When you let off the gas the vac line releases the pressure and the spring and vac will cause the valve to open letting air out of the charge pipes via the holes near the bottom of it

I hope this helps you and you understand what I am saying..... lol its 2am here and I have been drinking so bear with me

 

but it seems like the seal is bad or something on the bov and i think it might just leak boost when it is installed.

 

all the top does is read vaccum, hook a vaccum line up to it and your good to go. it has to read the air so it can open and go "PSSSHHTTTT"

 

yeah but i have a feeling when i put this bov on, i will get a boost leak. i blew into the nipple so see if it was sealed or not and it wasnt.

 

Post a pic.

 

Install it and see what happens. Boost leak won't kill you.
