check http://www.scoobymods.com/ for the write up. I think most end up just getting a full recirc. BOV anymore if needed. The stocker is good, uncrushed, up to and over 20 PSI, tho.
This is a discussion on "The BIG BOV thread" (Where all bov question threads get merged) within the Engine Modifications forums, part of the Tech & Modifying & General Repairs category; check http://www.scoobymods.com/ for the write up.

All BPVs/BOVs (stock and aftermarket) HOLD the boost until it NEEDS to be released (such as when load is taken off the engine to shift), and in essence, BLOWN OFF...
The mashing of the stock BPV is a little performance trick, but it isn't necessary at all because the stocker does hold upwards of 20+ psi. We will not be seeing that increase in PSI until you do a turbo upgrade. I'm at Stage 2 on my STI and see a max of 19.5psi.

If you insist on doing it (for no apparent reason) there are a couple options, but keep in mind they are not reversible. One is to do it the conventional way, by removing the valve and using a flat surface vise slowly, the refitting the valve and doing trial and error repeatedly. If you are lucky, rich, or have a large BOV collection plus a block of wood and a hammer, well, I'll let you do the math... But I'd be really careful and not opt for the hammer route.
Or, you can remove the valve and block the small hole on the surface that mounts to the IC -- not the big hole. Weld it or something. Seal it well. Then look at the other hole's routing through the body of the valve, and drill into it (use a 3 mm or so drill) to vent the *opposite* side to atmosphere.
Or, don't do any of this and forget the whole deal. Probably the wisest choice. If you don't follow what I'm saying, don't try it. If you are reluctant to try this, you're right, don't. If there's any doubt, there is no doubt -- don't do this.
