Im in talks with a member about buying an intake, we were talking, I said my current intake (gen3) has three ports. One is from the BOV (one is from the little catch can above valve cover, I forget the third right now).
He said that his, also a gen3, was not like that.
My swap was done by someone that has done some questionable things...Ive got evidence of said questionable things on my car from swap. So Im interested in seeing a pic of the BOV setup of a stock unit, please.
Your intake is setup correctly, the top is for the PCV as you mentioned, below that is IACV, and then finally the recirculation valve. Unfortunately I can't find a picture of the stock gen3 engine to show how it looks.
The small hose from BOV goes to the TB vacuum line which is correct. What is different is the aftermarket valve in parallel with BOV which should be the stock VTV. This could easily cause an issue as many don’t understand what this little valve does.
Id simply pinch off the vacuum line and try running with BOV incompacitated. Many of us remove and blank off BOV completely without any issues.
Depends on the version of engine. GEN2 doesn't like it much. GEN3-5 doesn't care.
I read somewhere that at idle the stock valve opens up letting air bypass the turbo. How true that is, I cannot confirm.
Based on the situations of when venting occurs on the GEN2, you might lose metered air but you have the throttle plate closed so the fueling might be more rich and not actually affect the safety of the engine but speaking with people who have vented the GEN2, the engine didn't run too well during shifts.
Well I have a gen3 so that's good news, thank you.
When I got the car the bpv/bov was routed to the intake...it was a shoddy job.
But on this racerx intake I only have two ports on the pipe, so I wasnt sure about what to do with the bov
Ah yes. I don't know why I didn't see the first few posts in this thread. Yeah GEN3 is all to vent. I'd be curious if you can confirm that it holds shut at idle.or of it opens. Old why I have this idea in my head.
How can I confirm that for you, let me know and I'll try
