I replaced my BPV with a new one because My boost guage would bounce when I floored it and you could hear a wha-wha-wha coming from the engine compartment in time with the boost guage. When I did I checked all of the turbo piping clamps on the pressure side and found two loose clamps one that was a lot looser than it should have been. It turned out to be the clamps that caused my problem.
Also, the BPV holding vacuum is only for when you come off the turbo. Spring pressure holds the valve seated until you let off the gas and then vacuum opens the valve dumping boost back into the inlet side of the turbo. Sorry if this is old news. Just, you could be boosting both valves right off their seats if the springs are weak. The fact that they hold vacuum would make no difference.
