Sorry. But another BOV question.

So I put an agency BOV on and I love the sound. But I’m concerned about one thing. When I’m running just normal, there constantly air just leaking out of the BOV. Not the loud swish sound. But like an air leak. Does anyone else have this. Just sounds like air is coming out a lot more than it should.

Rzr joe. I read your post awhile back and was very helpful.
But the agency BOV doesn’t allow for any extra spring tension besides the knob on it. Maybe I will tighten it up a little more and see. I just know zero about these things and wanna make sure I’m not doing damage to anything. Thanks again Sam

Re: Sorry. But another BOV question.

I feel like maybe RZR_Joe meant to post this link?

How do you have it plumbed? How did you adjust the spring pressure setting? Here is a good install guide.

The basic idea is that the valve should be closed at all times except at the moment you release the throttle while you were making boost. So just normal driving around it should not be leaking by.

That’s exactly what I was after. Man I love this site. I never worry about screwing anything up at all when I have people to lean on and ask basic questions. Thanks. Sam

Re: Sorry. But another BOV question.

I've got the exact same problem. Spoke with the guys over at Agency, it's common. They sent me a replacement and it still leaks at the tightest adjustment. They said they are working on a remedy and will contact me when it's figured out. Been a couple months and haven't heard form them

Ok. I knew something wasn’t right. It’s not supposed to do that. Will call. Thanks.

That's because it's just a cheap Chinese rebranded BOV they sell for 3-4 times what you can buy the identical BOV for without their logo. The biggest problem with these cheaply made BOV is the poor quality of machining and seals.

A good BOV does not need to be expensive, see the link above. It should not be open at idle.

I just called agency. And they told me I have to remove the BOV and apply die-electric grease to something. I can’t even believe the poor customer service there. I said to her. Well. Why would I have to mess with a brand new product.
Then I asked her how to apply the grease. She said. I have no idea.

I told her, well I just want a different BOV. She said nope. I gotta apply grease first. Unreal.

Re: Sorry. But another BOV question.

RKX valve, Yellow Spring, .400” spacer, orientated opposite of the OEM BOV. Problems solved.

If you seriously want it setup to operate like OEM, then plumb it in the same orientation as OEM, use a vacuum pump, and play with the springs until it opens at about 11” hg, it will leak at idle and part throttle like the OEM and aftermarket valves do, and operate the same otherwise for relief purposes.

Don’t have a vacuum pump? You can buy the RKX, and a vacuum pump from Autozone, and still be in it less than an AA/Agency/Evo etc... and now you’ll have a vacuum pump too.

It is imperative that the cap is sealed for any of them to operate correctly, but you can’t fix poor MFG with some grease. That RKX setup that Joe wrote up works perfectly, and is so much more cost effective. I can’t speak for him, but I’d be willing to bet that a PM to Joe would even given you better “customer” service than agency lol.

thanks alot dude!! the .400 spacer/washers eliminated 99% of my issue, well I only put .368 worth of washers in there so its closed for the most part and operates like it should except it slightly opens off throttle on deceleration so imma buy and add more washers to get to .400 a d hopefully that little more spring pressure does the job. 😎

Joe did all the grunt work on that, all the thanks goes to him, but he did it right and shared an excellent setup for less than 1/2 the price of the options out there.
