How do you bypass the BOV solenoid and where do you tap the vacuum line?

[JDM_Man]

So there has been a lot of talk about bypassing the electric solenoid that controlled the stock BOV's but where do you need to tap it from?


Everyone whose done this where did you end up connecting everything and what did you do with the open holes on the solenoid?

Thanks!

I tried it and ended up going back. It didn't seem to respond as well.

This blog by Mishimoto will give you all the information you need. It's the little grey rubber line you remove that's circled in orange in one of the photo's.

The manifold vacuum source is the grey hose near the throttle body. It passes through a check valve then into a vacuum tank. The vacuum input to the solenoid comes from that tank.
so if you just want to run manifold vacuum, then pull straight from the manifold (not the tank, and remove the check valve)

Wouldn't you want to leave the check valve in so nothing gets sucked into the vacuum chamber? Also where is the check valve for that located?

The grey tube you disconnect is the check valve.

errr..... the "blow off valve" would always "blow off" if the check valve was still there.....
I'm 95% certain the check valve, at least on my '18 v6, is a separate disc style inline check valve. Pretty obvious once you look at it. Too lazy to actually open the hood though - all my car energy was used up today doing Yet Another Custom Master Cylinder Swap. *sigh*

Hmm my HKS bov won't open fully despite going off the intake manifold or sylenoid. Using 4mm hose i hope tue move to 6mm may open it better

I doubt that would make a difference. You might need a softer spring.

Its a HKS they are designed to open with like 1psi and you can change the spring
