Default Greddy Type S Bov Bolt Replacement?

Hi guys, I have a Greddy Type S Bov, but I am missing the top bolt piece for it. Would anyone happen to know what kind of bolt it uses? I was thinking it could use any bolt that it could fit. When we installed it with a bolt on it, my car would idle really funny, like it was leaking air or something. Any clue?

To be honest you should just use the stock recirc BPV. Most of those type of after market BOV leak. When you VTA you are letting out metered air and cause your car to run rich. Does your car currently backfire? that B why.

But if this is all info you knew I will let that go and say take it to lowes and find a bolt that fits can you take the whole thing apart? What does that bolt connect to inside?

Stock BPV is good to 22.5-23psi of MRP at our altitude. Go back to stock and or make sure it doesn't leak!

Get a speed density tune and run a tial. Perrin, tial, aps are about the only brands I recomend. Both perrin and aps you can run either vta or recirc.

Take your tmic off and build a pressure tester to put on the 90* coupler. You will need to block off the throttle body with a cap from home depot. Drill and tap a fitting for the bov hose in that cap so the when you start pumping it up it will have pressure against the diaphram. Now watch and see where it starts to open up or leak
