Will this work?

Since all my money went into dealer only parts to fix my supra (everything from turbo gasket set to door hinges) I am left with no money to buy a real BOV. Besides they are like $200 anyway. So I modified the stock bypass valve as seen in this picture-

Now, I rode around and no CE light , but I think I got a few lean pops from the exhaust (i dont know wasnt really paying attention). And it releases boost for quite some time, its not a quick whoosh but a long one lasting up to 3 seconds depending on the amount of boost it was making.

I know the air is blowing out of that hose I have just hanging there, but is air going back in? The basic principle of a turbo would have me saying no, air is only going out of that hose.

Any thoughts?
