    Problem with BOV

    Before you guys tear me a new one, I know BOV's are not ideal on these cars. This car came with one, and damnit, I can't help but like it. Anyways, my BOV is no longer blowing off boost unless I'm at full boost. It just makes the fluttering sound that it would normally make when you come off throttle just above vacuum. I haven't touched the adjustment screw on it, ever, so that shouldn't be it. I did however have a bit of a nasty run in with a large puddle. My car started running extremely rough for a bit, unable to rev past about 5k rpm, and the check engine light was flashing (it's always on, as I get the P0420 code on a regular basis since I have no cat or o2 sensor on my downpipe). After a few minutes, it actually stalled out completely. I started it back up, limped it into the nearby parking lot, and let it run for around a half hour or so. When I got back in it afterwards, it seemed to be running fine. I haven't had a chance yet to take it into a shop to get the CEL codes checked. Before I do that though, I was wondering if there's any things I should check first? There's nothing stuck in the BOV, as best as I can tell, and the adjustment screw hasn't been touched. Could it perhaps need a bit of lube? If so, what would you recommend using, and how?

    Thanks for any help you can give me,
    Bob

    Let's back up here. You are running no O2 sensor on your downpipe? Understandbly, the rear O2 sensor is intended to mainly check the efficiency of the cats. However, if you deleted the O2 sensor, your tuner should have defeated the CEL. Who does your tuning?

    Also, it would be nice to know your car, year, and mods....

    I'm not sure who tuned my car to be honest, it was tuned before I bought it, and i've made no major modifications since then, other than a lightweight flywheel and stage 1 exedy clutch.

    As for my car, it's an '04 wrx 2.0L
    3" catless turboback
    bov
    stage 2 mbc
    short ram intake
    ACT streetlight flywheel
    exedy stage 1 organic clutch
    and for ****s and giggles, HID headlights

    Obviously I don't want to be driving the car very hard and build up any amount of boost if my BOV isn't venting, so I beleive it's important that I get it fixed asap. Again, any help is greatly appreciated

    If the car is flashing the CEL, then it's likely NOT tuned at all.

    As touched on in this thread in the Unabomber's Manifesto
    Aftermarket BOVs can and do require some light end user maintenance to keep them performing perfectly.
    What brand BOV do you have? If you can find out, then do a google search for "BrandX BOV maintenance", and oil it up.
