Mrstacy Posted October 12, 2017 Share Posted October 12, 2017 The installation instructions are for WRX/STI. Does anyone know where the white sensor in the photo is on our cars? Thanks in advance. Link to comment Share on other sites More sharing options...
Mrstacy Posted October 12, 2017 Author Share Posted October 12, 2017 I think it is the crankcase ventilation hose (CCV) Reading these instructions: https://forums.nasioc.com/forums/showthread.php?t=2742210 Link to comment Share on other sites More sharing options...
Mrstacy Posted October 13, 2017 Author Share Posted October 13, 2017 I sent a PM to Big Bopper since he did an install of version 2. From his V2 instructions, it appears he tapped into one of the ports on the charge pipe. There are two identical ones and he capped one off. What are these ports? http://legacygt.com/forums/showthread.php/5th-gen-lgt-performance-mods-202211.html?p=4308126&highlight=crawford+extension#post4308126 Link to comment Share on other sites More sharing options...
BBPeik Posted October 14, 2017 Share Posted October 14, 2017 I am pretty sure the left one is the PCV and the right one is the Blow by pipe. My someday I will be done with it thread. Link to comment Share on other sites More sharing options...
Mrstacy Posted October 15, 2017 Author Share Posted October 15, 2017 ^ ok thanks. i'm getting closer to understanding this then. Here is a diagram of what I know (and don't know so far). No rush as I have no oil on the TB hose. Link to comment Share on other sites More sharing options...
Mrstacy Posted October 15, 2017 Author Share Posted October 15, 2017 After getting a PM from Big Bopper and looking at the instructions again. i'm thinking port 4 goes as shown below. That line leads to a metal tubing going down. so maybe it connects to the cold side turbo inlet below which would go to connection 3 to close the loop. Not 100% though. I'll take off bottom tray at some point to follow where it goes. Link to comment Share on other sites More sharing options...
BigBopper Posted October 15, 2017 Share Posted October 15, 2017 The installation instructions are for WRX/STI. Does anyone know where the white sensor in the photo is on our cars? Thanks in advance. 2010 LGT does not have the electronic check valve ("white sensor"). Don't know about 2011 & 2012 LGT. Link to comment Share on other sites More sharing options...

In OEM configuration, 1st nipple on left side comes from L&R valve cover breather hose ports. Next nipple to the right comes from crankcase vent below PCV. These two nipples/lines introduce the oil mist/blow by you are trying to eliminate from the intake, by installing the AOS. Link to comment Share on other sites More sharing options...
Mrstacy Posted October 15, 2017 Author Share Posted October 15, 2017 ^ thank you. So, if i understand correctly i have to account for both of these, since just using one of the two lines would leave the possibility of oil mist/blow by. Link to comment Share on other sites More sharing options...

Mrstacy Posted October 15, 2017 Author Share Posted October 15, 2017 Houston, we may have a problem. The V3 may sit too high for Legacy GTs. Not sure what i'll do now. I was counting on this one. http://legacygt.com/forums/showthread.php/crawford-aos-install-questions-264629.html?t=264629&highlight=aos+hose Link to comment Share on other sites More sharing options...
