BOV not Blowin off

[ATLDSM96]

I got a greddy B.O.V. and i got a custom upper intercooler piping and when i blow off the noise comes from the intake not the actual blow off valve. What could cause this?

That sounds like compressor surge. Try to loosen up the adjustment on the bov.

There should be a little set screw on the back of the BOV. If you loosen it up a bit that should solve the problem.

i loosened it almost all the way and the it still does it.there is a second nipple on the B.O.V. what is that suppose to hook up to?

 

[snowborder714]

Do you have the vacuum line from the bov to the intake manifold? Also, make sure there's nothing teed into this line.

 

[ATLDSM96]

yea i have the vacuum line hooked up. but there are two nipples of the back of it.

 

[snowborder714]

As far as I know, the only 2 lines that need hooked up are the recirculation line and the vacuum line. That should go for any bov.

can you post a pic of your BOV setup?

i have the GReddy Type RS

 

[snowborder714]

After looking at pictures of the real Type RS, I only see one nipple coming off the back. Where are you seeing 2? Are you sure you have a real Greddy Type RS? I saw some on eBay that looked like one, but it had 2 nipples.

Also, on the real Type RS, it seems the nipple is just screwed in. So, if you have a real one, the bottom one (I can kind of see where it might go in (on the back below the top half) might screw out.

As stated in the post above, please put up some pics.

Guys, he's got the type s it sounds like. That second nipple is not manditory but you can hook it up to a secondary boost source, for better response.

His profile says Type RS.

His profile says Type RS.

It's sounds to me that he doesn't know what he's got.

yea, the S has 2. you hook the upper one to the vacuum line. lower to boost source for better response if i remember correctly

what color is it? most S ones are purple

All greddy type s's are purple unless they were painted.. If you have two nipples you have a type is. Connect the one at the top to a vacuum source, and if you want you can connect the bottom one to a pressure source coming off of an intercooler pipe.

Isn't that what I just said?

 

[bjbaxter]

Definately sounds like the type s to me as well. You need to post up a picture and let us see it ourselves so we can determine that. It's probably the only way we can help you out as of right now.

 

[ATLDSM96]

Yea sorry about the miss print in my profile but its a type s and its purple. ill get some pics up today.

 

[snowborder714]

Well, my bad everyone. I was wrong.
