Default bypass?

Is there anyway to bypass the PCV valve/charcoal canister assembly by routing the vaccum lines a certain way? 88 CRX Si.

Discharging excess fuel pressure into the intake manifold isn't helping anything.

fuel pressure? i thought it was positive crankcase ventilation. i think you can get an oil catch can if you don't want to use the pcv valve. that's what i'm going to do when i install my turbo.

Just disconnect and plug the lines that go to it. I wouldn't bother though, all that does is burn off tank vapor and crankcase fumes. If you disconnect it your car will just pollute the environment more and you won't gain any HP. The purge valve on the canister will not open when vacuum is low, only when it is high, the better to suck in the fumes. When you are accelerating vacuum drops almost to zero at WOT, therefore the thing won't open and there is no performance loss.

The PCV and charcoal canister are two different things.

The line to the canister from the fuel tank can be capped, and the vacuum nipple on the manifold coming from the canister can be capped.

Simply put, the PCV valve and lines need to stay.

Yeah, because I disconnected everything and it made my idle 2500 rpms.
I'll try it the way you said Kai.

Does it screw with performance at all?
Throttle response?

Then you forgot to cap something. Higher idle = too much air = vacuum leak.

No, and no.

lol
So is there any advantage to bypassing it aside from a very small weight reduction and less shit under the hood that does nothing?
I capped everything and it still did that.
