    Hey guys, recently I started a thread on my 420a turbo car I bought, please check that out to know the story on my car. Now back to the purpose of this thread. There is a Greddy Type rs bov on my car that I bought, I noticed that the bov wasn't "blowing off" so I took a look at it. First thing I noticed was that the adjustment screw was actually upside down so that the Alan key hole was actually inside the bov. I then noticed that the threads inside of the bov were destroyed and cross threaded, so that the adjustment screw would just slide and do nothing. Can I create new threads? I know how to cut new threads and all but my question is would it affect the bov? Would a new adjustment screw a little larger affect it?
    Thanks.

    Save the troubles and get a 1g bov. Much cheaper and works better. The greddy rs sucks. I had one too.

    Sure the 1g is a possible option, but I wasn't sure if it was an easy fix or not.

    Honestly, you can pick a 1g for around under $100 and it will be less expensive then trying to repair that.

    Or even search the classifieds for other Greddys.

    All these guys are saying buy new stuff. I had a RS i bought here for 40 dollars. All it needed was to be threaded. Saved over 90 dollars just by fixing the problem. Thread it. Make sure the bottom of the bolt is rounded. The top will need to be locked with a nut. You probably need a thicker bolt since you are widening it by threading again.

    Only 30 bucks for a 1g bov, which is a great investment for your car. Or mickey rig a rs. Pretty plain choice there.

    I have a greddy rs. It was stripped when I bought it. I just retapped the hole to a bigger size. Also had to replace the diaphragm. After all that I finally got a working bov.

    Yes you can re tap it. Go to your local AutoZone or harbor freight and get a Tap and Die set it will come with a tap-drill bit size sheet go 1 one size over the current bolt. And like stated above make sure it is rounded line the original bolt. AutoZone has a full kit for 30$ which will work just fine on the mild aluminum. You already have the greedy KEEP IT. Why down grade to a 1g bov. DSMs are not the only plateform the GReedy RS has been used and is proven on. It is a great bov. Keep it, fix it, and boost on.

    Honestly I would see what you could do with the BOV you have, And if it doesn't work no big deal your not out of anything but then you gotta go buy a new BOV anyways. I would explore the tap and die idea first see what could be accomplished.
