"How-To" SHO and Flex convert to vent to atmosphere with factory blow off valves

Out of curiosity, why not?
When the valve is closed, the opening is just a port; it doesn't go anywhere. When the eBOVs are open there is positive pressure, so my understanding is that there's really no way for anything to enter the system past the eBOVs even without a filter.

I can't think of a way to even test it... so on the hotpipes I had the number of ports doubled... the actual valve seat and BoV plunger are visible... No problems for 1800 miles or even when I had the engine detailed and a pressure washer was used. I have the concern also... just don't know which is best.... need to think of a way to prove it one way or the other.
As another alternative to those interested, I only disconnected from the BOV side and left the intake side of the tubes attached. I then found the appropriate size "plug", which turned out to be a 1/2" PVC Cap. I pushed the caps into the tubs and pulled the clamp back up over the caps. Seems to be working well so far, and should be easier to reattached to stock if I want to for warranty work.
did mine this morning with these stoppers for $4.00 ea from Advance Auto. The front BOV off definately audible not too loud. Both off a little too loud for my liking. The rear only off maybe just right.
*****IF YOU DO IT THIS WAY.....use your common sense and DO NOT overtighten these plugs or it could split the intake pipe especially since there's a seam on the plastic that runs though these plastic ports. I turned mine about 1.5 full turns and it's plenty snug to not come out. 1 turn may be plenty depending on how snug it is when it goes in. Enjoy....

Pretty slick solution for sure and much easier to get !

It does look sharp!
One question 68:
If the nut comes loose can the bolt fall out?… Obviously this would be bad in a turbo feed line…. I just don't know the expansion plug you used.
I was going to use something like this for my RX catch can install, but Tracey told me they just use drilling to eliminate the chance of solid objects in the intake.
I took the plugs off yesterday too much rish and the bolt was too short with that nut on to have anywhere for a cotter pin to go through it. Maybe if I can find a thinner nut I can pull it off.
Weird thing is the car seemed a littel down on power while venting out ??? Probably beasue I was listening to the new noises I guess ?? Anyone else ever think this ? make any sense at all ???

I'd drill thru nut and bolt or find a small castle nut.

Maybe since it's vacuum (intake) tubing the silicon cap is a better idea... I have had Locktite fail on firearm scopes occasionally, so I personally wouldn't trust it... not even the red version... consequences of failure are too high (new turbos).
Can't speak to the real world performance... times, etc.... but no dyno difference when VTA.
Maybe some prevention of exhaust gas recycling getting concentrated a bit from PCV system by not recirculating blow-off to turbo feed piping.
