so after installing my efr i have a hose that goes from the valve cover to the factory turbo just dangling doing nothing... do i need to do something with that? i been having problems with the car for a while and dont know if that has anything to do with anything. it sucks in air and dont know if it needs to be rerouted somewere. any help?

 

I'd assume it get connected to the intake like the other one is

 

You technically only need one line.

 

i been throwing this code p2187 for the longest and i cant any leaks... u think this being loose might couse that code?

 

Why do they have 2 breather lines anyway, one to take in air and one to expell excess air or what's the deal? Only seen this on lnf

 

so what can i do with this line?? plug it???

 

Since the air goes to it from the intake, after the MAF, it is therefore metered air. If you then have a way for that air to escape back out (the other hose on the back) without reintroducing it back into the intake airflow, you have created yourself a vacuum leak. The air is metered and then disappears as far as the ECU knows, and the car then runs rich and the fuel trims must attempt to correct for it.

You need to pipe the back hose back into the intake, like it used to be when it was on the stock turbo. You could possibly plug it / cap it, but I'd have to think about that one.

 

ok that shouldnt be a problem i think i can find a way to recirculate it back to the intake

 

Yeah, recirculation would be the best option in my opinion.

 

scott ftw!

got to it before me. :P

 

Its just unmetered air, not a vacuum leak. Vince would just have to adjust trims accordingly.

 

Tuning for it is a bit of a bandaid though. I was just trying to explain the proper way to fix the issue. The air for the PCV is most definitely metered. Check out where the PCV is in relation to the MAF. The air going in there is accounted for at the MAF, and then ECU isn't seeing it show up on the scene like it's supposed to because it snuck out the back door.

Metered air leaking = vacuum leak, just like a boost leak is considered a type of vacuum leak. In both cases you have air that's been accounted for leaving the system that the ECU thinks should be there.

 

that makes perfect sense to me sir, thanks.... ill have a shop around here put a nipple (yea i said nipple) on my intake and connect that to the hose if possible and hopefully that fix my problem then off to retune my baby and make some decent power . Thanks for the help guys

 

I hope you get it solved too man.

 

thanks bro and i pmd u

 

lol, no, you don't have any air leaving the system. It would be entering the system from the engine via the valve cover. Thats why they call it positive crankcase ventilation.

 

It comes in from the intake, after the MAF, and then returns out and back to the turbo. It's a closed system that is no longer closed if one hose isn't connected.



Edit: Fixed the picture. Hosted it here, since it didn't like being linked to. ^

 

Yes, you actually made sense that time, lol. Somewhere along the lines previously you said air would exit the intake system which had me confused. Yeah, I don't see any reason why it wouldn't work like that. What kind of intake does the op have though? Is his elbow to the turbo all silicone? If so he may need fitting of some type that can clamp down onto the elbow itself after a hole is cut.

 

I'm not sure. I think all the SS/TC intakes currently offered have the "inlet" side of the system plumbed into them. I think he didn't have the "outlet" side that normally plugs into the stock turbo location plugged into anything since there isn't a place to on the other turbo, so he'll need to make a place on the intake just before the turbo and hook it there.

This was a topic I brought up a few months ago...


That's right, I just quoted myself. It's something I've been wondering though. Is there no hookup on the ZFR even? If not, more people are going to need to decide what they want to do for the PCV system.


This is the solution one member came up with:

 

Yeah, the K&N and Hahn are nice like that but my AEM I had at one time and I think the Injen are not like that.

 

So I have the same problem, My PVC is out. Do I just reroute back into the Intake?? I also have one nore vacuum line from the DV valve not going anywhere. Is that okay?

 

Sounds like ZZP needs a revised air intake tube.

 

Or give some instruction on what to do..

 

I had to do a quick hack job on mine couse i was getting tuned the next day but it worked and i havent had a code thrown since... But i just drilled a hole for a 1/4 inch nipple and put a hose over the braided line then a hose in the bigger hose as u can see in the pic lmao i know hack job

 

Thanks bro, I might have to do that as well right now. One more question. the nipple on the EFR for the Divertervalve, did you plug anythign into that? I just have a hose thats out and plugged up. James told me just to unplug it and i'll be fine. I just want to knwo what you did cause we're like the only 2 people lol.

PS, can you PM me your number. I really needed your help yesterday as you have a month more EFR experience than me! LIOL
