great so today after my girlfriend took my car out for a oil change. she came back with my bov mounted up to my top mount. so i was like great blah blah blah. took the car out for a spin and just heard a whoosh no high chirp like the hks suppost to have. check the welds they where good.. looked at the line hook up for the bov and im guessing it was right..any solutions for my girls great work.

Do you have the center Y shaped piece installed on the BOV ? Thats what makes the whistle.

So if you didn't have it hooked up to the top mount before, where was it previously installed?

Whats your vacuum source for the valve?

i didnt have it hook to anything. i hardly drove the car so it sat most of the time. the vac source is hooked up to the boost gauge in i have a t there now one going to the intek one to the boost and the other going to the boost gauge. i dont think it matters just as long as the bov has vac right??
ok i just went and took a look at my bov and it seems to opening at idle and when i rev it up it seems as if the hks is being kept open. it blows out air and all but it doesnt make any noise just WHOOSH!!!!!!!!!

I have no clue what you mean by top mount, since you have a 5SFTE.

You need to be more specific as to what your girlfriend changed around, exactly. Then we could better help you figure out what might be wrong.



Personally I would use a dedicated seperate vacuum line for the BOV entirely directly off the intake manifold. If you tee'd into the line going to your boost gauge, that might not be ideal for the actuation of the BOV. I would tee into another source of vacuum from the manifold for the boost gauge, but it really shouldnt matter too much if you tee into the line for the BOV, just not the other way around.

But bottom line is you need to be more specific about what exactly she changed around. Whatever it was I'm sure probably caused this change.

That, still doesn't answer much. I still have no clue what she changed around... wink.gif


Well the answer is simple as to where your lines should be run on the 3rd gen 3SGTE. There is a dedicated hardline that comes off the intake manifold where the bracket for the factory oil catch is located. That provides a factory location for the BOV's vacuum supply.


I eliminated the evap canister setup when I did my swap, and since the ST205 canister uses a vacuum source from the throttle body I just looped those two vacuum sources and put a tee right in the middle for my boost gauge.

If you use that vacuum source for your BOV, and the valve is connected on the diaphragm side to the top mount intercooler outlet or intercooler piping (whichever you have), you should have no problems.


Post up some pics of how your BOV is hooked up. I'm still confused as to what you are saying your girlfriend did to it....so at least if you post pics I can see how it is installed now and take it from there.

i dont get it. you said she took it for an oil change? why would they screw around with your blow off valve? to me thats saying, the place that did the oil change, screwed up your blow off valve. meaning you could of taken it back, and said hey you screwed this up. hmmm

This is why people should do their own swap.

haha ok guys im just not sayin it right.... i did my own swap i know what i know about the swap.she took the car out for a oil change and came back with the bov hooked up to the top mount. (its no problem when your girl just wanted to do something nice) so when or while she took the car out for a oil change she decided to take the top mount off and had them put on the bov .....the insert color of the hks is purple. while i was tryin to figure this out and look for help. i decided that there was no real point of posting this. i just called hks and had them send me a stronger spring that was the problem if thats not the problem then they said that they will just replace the bov for me. so thanks guys for the reply and help.
the bov is hooked up the intake manifold. the boost gauge is hooked up to intake manifold. bov is just not reacting right.
so this is why people should learn how to do there own swaps.

Thats how the purple insert sounds.
Normal hks sound that you are thinking of is with the silver insert.

Bingo. I wondered why this all blew up before anyone asked the right question. The BOV is acting exactly like it should. Just get the silver insert and you'll get the HKS sound.

i was about to suggest that the spring was too weak for the amount of air pressure (same thing happened to mine) put more washers in there to strenthen the spring and all better!

What doesn't make sense to me is that he said that he put HIS HKS bov on his friend's car and HIS "chirped". I don't understand why it would suddendly make the "chirping" noise assuming he was still using the purple insert.

Meaning he put A hks bov on, not HIS hks bov.

Thats the best thing about the hks. There are no springs or washers to adjust. Boost actually pushes WITH the diaphragm to help seal it closed. The more you boost, the harder it seals!
