I don't have a dash hawk or boost gauge, so how can I tell if my stocker is effed. I tried searching and apparently the term BPV doesn't bring up anything.(deadhorse(deadhorse
i remember seeing somewhere that if you take the bpv off and de-press the diaphragm and covered the recirc fitting and it didnt hold suction then it was bad.
Get a gauge. Borrow a gauge. Respectfully, stop guessing. All that "test" you describe will tell you is if it's totally shot. That's not a good way to check for high pressure leak downs or erratic behavior, IMHO. If you are going to mod this engine, you need to know what it's doing before you add the mod or make the change and how it's responding to the mods.
