Topic: BOV bung blanking on aftermarket charge pipes

[iflyme]

Hi all,
For Christmas, my wife stepped up her gifting game and got me new charge pipes and CAI from RPM-Motorsports http://www.strictlyaftermarket.com/select-vehicle/saturn-sky/intake-exhaust.  Pretty cool wife, right?

However, she got me the set with the BOV Bung.  I'm not ready for that and I was advised that until i do some major work, that a BOV is ill-advised on anything less than 400HP (generally speaking).  I will be installing a CAT delete and purchasing a HP Tuners tune once everything is swapped out.

So, other than the charge pipes, CAI, CAT delete and a new tune, everything else is stock.  I don't want to do something stupid and I couldn't care less about the BOV noise.  What I do care about is doing something with that big, gaping HKS BOV bung.
Questions for the more experienced folks on here:
1) Will it cause issues if I just purchase a BOV (a genuine HKS, not a knockoff)?  Pros/cons of just installing one, please.
2) Is there a way to plug the bung hole?  I was thinking a good gasket with a stainless steel plate, but then I'm not sure how well that would work.  The flange for the HKS BOV screws on to the charge pipe, so I could possibly even try to find a thread-on cap, but not sure how I go about doing that.

Any thoughts and words of wisdom are greatly appreciated.  I've searched the web and just can't find a solution on my own so here I am looking for answers.

Cheers, all!



PS. I tried to attach the photo of the bung, but in the "attachments and other options" area, I'm not supplied with a selection to attach anything.  So, if you're curious to what I am talking about, click the link above and scroll half way down until you see the red charge pipes with the BOV bung.

I would contact the vendor and see if they make a blanking plate to cover up that hole.  I am assuming that the BOV would be held in place with a V clamp so you will need one of those too.  A quick google search for BOV block off has a lot of options, you will need to know what diameter it is but you should be able to find something.

If no vendor has what you need you could probably take the tube and clamp to a machine shop and have them make one for you.

Welcome to the forum and if you want to see how I added the pictures, quote my post and you will see I used the little button that looks like the Mona Lisa and then inserted the picture address in the middle.

Get an aluminum mating flange and v-band on order, start looking for a welder.  Probably use something thin like 1/16" aluminum to block off the flange.

Thanks Steelmesh and Sol Asylum. I don’t know which of your posts got me thinking clearly, but I got to wondering how the HKS BOV actually attaches to the flange. So I did some digging and figure I can buy this HKS SSQV BOV installation kit
  and fabricate my own blocker plate.  I’ll get a piece of thicker-than-necessary aluminum, cut it into a circle and grind down to chamfer the edges like the plate in the link Sol Asylum has.   I’ll squeeze the O-Ring with the plate and install the C-clip.  combined pressure from the O-ring and the chamfered edge should keep the C-clip in place.

I don’t want the two metals to corrode (assuming the cup is stainless steel) when I run into a salty environment so I’ll probably coat the blocker plate with high heat clear spray.

No luck on obtaining a blocker plate from the manufacturer, but I enjoy making stuff on my own anyway. Now I just need to figure out the thickness of the aluminum that I need. Can’t wait until I get home to have more fun with this project.

Could you just pick up a blow off valve blanking plug from someone like Summit Racing? They have lots of different styles, the one below is just one of them.

I looked at those already. They seem to be blanking plugs for all the hoses that are no longer used when installing a BOV.  I just don’t see how those would attach to the Bung that I have already on my charge pipe for the HKS style BOV, either.  But if I’m mistaken, I’d be happy to be told so.

You could see if you can find an expansion plug locally that would fit.  Still use the snap ring and O-ring with it.

Sol: expansion plugs you say?   Now THAT is intriguing.

[Sol Asylum]

Yep, it's just a metal disk and should work as a plug.  Most automotive machine shops have them and they are not very expensive.  Install the O-ring drop the plug in and secure with the snap ring, as long as it's thick enough to compress the O-ring you should be good to go.

Bought the HKS SSQV C-Clip and the O-ring (10 bucks), two pieces of 1/8" aluminum scraps from Alro and a good 2-1/4" hole saw.  I removed the pilot bit before using the drill press with the hole saw attached.  I took the resulting disc to the grinder and wire brush. Used the bench vise to push the disc and squeeze the o-ring so the C-clip woiuld fit.  Great!!!  It was supposed to be a test fit, but the I couldn't seem to get the c-clip to relesease even when applying force again.  so... it's installed.  I'll keep an eye on it for dielectric corrosion.  If that happens, I'll have to get a little thinner metal and paint it.   Fingers crossed it all stays happy

Took the girl out for test run.  Boost is still around 24 PSI (The Trifecta budget tune still installed) so I'm happy!  Now to delete the cat and get a new tune.

Great news, here's hopin' you're done with that.
