2G Getting BOV Intercooler Seal to Stay

[Ferp]

So I'm having a problem where my blowoff valve ring seal that is part of the ic piping pops up under boost, causing a massive boost leak. I can't get it to stay in for the life of me. Any suggestions?

Correct me if I'm wrong, but I don't think you can secure a BOV to intercooler piping with just a hose clamp. I'm pretty sure you have to have that flange welded to your intercooler piping.

The problem is the smooth surface there to which you're clamping. Without a lip or something there you're really not likely to get that to hold. You could get a shop to weld a small bead on the end around that flange which should do the trick. Alternatively, if you are feeling ghetto, you can make a bead out of JB weld yourself. When I've done this in times when I needed a quick fix I used duct tape to layer up a channel, then a applied the JB weld in the channel using something like a toothpick or something and let it set. Of course make the surface as clean as possible prior to doing this.

Could just use hairspray and a quality t-bolt clamp too. Just saying.

That hose clamp looks like it can't really handle clamping the intercooler pipe onto that rubber gasket/grommet and then finally onto the BOV. The whole system doesn't seem right, the BOV uses a completely different flange. Lots of potential for leaks there. You'd really want to get a hard pipe with the proper flange welded onto it. If you're trying to save money and just want the noise and don't really mind a potential boost leak you can try the hairspray and t-bolt method like CrackDSM suggested.

So I sealed the rubber to the ic pipe with silicone sealant and then I sanded the flange and now the clamp stays on tight and as of now I have no leaks.
