2005 Civic SI PCV valve

AEM's bypass valve does not perform the same function as Honda's bypass
valve with a similar-sounding name.

Honda's valve CLOSES once the engine reaches operating temoerature.

 

while a worthy effort, why are you wasting your time? he doesn't
understand the basics, doesn't want to listen, and so by definition is
unhelpable. he's bought into the aem shtick and that's that - he
therefore wants to learn by mistake. let him. all kids have to go
through that stage at some point.

 

Q: When should I use an Air Bypass Valve?

Tegger, I totally understand the difference. I posted the above info
for anyone wondering about the AEM bypass valve that protects against
water ingestion on their products, completely different animal than
the Honda valve.
