    Help! Stage two today, bolt blew off bpv!

    I went stage two today and as I hit boost on my way to work, this happened!

    What do I do? Looks like the bolt blew off under boost at 4k rpm. ..I heard a metal clang and let off.
    Help anyone!
    Is it safe to drive? Can I go into boost like this?
    It's still secure by the other bolt, but the side with the blown off.bolt is lifted by a millimeter. ..

    I would replace the bolt ASAP. It can cause a boost leak like that. Those bolts are only like a dollar from subaru and most dealerships will get them in in 2-3 business days if they need to order it. But that is odd for it to just fly out like that. Are you sure you tightened them down? Not trying to question your intelligence, but i just went stage 2 this past monday and i went over every bolt 2-3 time to make sure all was well.

    You may also want to consider a new BPV. I know the forge one is a great alternate. As you up the boost, and add power upgrades that crappy stock plastic BPV will become less and less reliable. I havent had any issues with mine yet, and ive hit up to 19 psi on my new tune. But the next thing i will be ordering is the forge bpv. Consider it a preventative mod.

    No actually, after thinking about it, when I tightened that bolt, it made an audible pop.sound, but was nice and tight. Guess that did it. It's broken in half, with half in the tmic..hopefully I can get it out.
    I was thinking about a forged bpv, I'll look into it, thanks for your help! I was hoping I didn't blow my bpv. My tuner is telling me to unplug the electrical harness to the MAF....

    You think I can get the bolt at lowes? Or at a nut and bolt store?
    Or is it specific to the.tmic?

    I mean I guess you. Could take the other bolt to lowes or a similar hardware store. As long as the thread pattern and length are the same then you should be fine. But I wouldnt. Probably bc im very ocd when it comes to my car and my bike and having two mismatched bolts would drive me nuts. But thats your call. I would stay out of high boost regardless until you get it fixed.

    Every bolt on that car has a specific torque rating that you snug it down to. I would get ahold of the factory manual.

    Called on the bolt today, they will get back to me, I asked for the torque value too, if I can't find a FSM.
    Thanks for the help yall!
