Nice solution for the 07 owners you found there!

Wow. You really went at that thing eh? I had this thought before, but never got around to it.
I was thinking it might be easier to buy a new barometric pressure sensor and wire it in place of the valve. |

I'm pretty sure we can wire in a 108kpa Baro sensor in place of the valve on the driver's side. Anyone have the pinout for the valve?

I installed the block-off plates this weekend myself. Without this thread I would have had more 'fun' doing so.
The driver's side secondary valve had water in it (found this out after the valve had sat on the bench overnight and warmed up a bit). I had no codes but for the past few months since winter set in, and with increasing frequency, I was getting an exhaust rumble feedback into the air-feed system. Because of the water the valve would open but not close after the air-pump cycled for the 30 or so seconds it was supposed to after start-up. It would after a few more minutes of either letting the car warm up further or driving it, eventually close. As with others I did essentially the same thing. The air-pump is easily disconnected and removed. The driver's side secondary valve (once TMIC is removed) and air-feed tube are both relatively easy to remove. I obtained a set of block-off plates from Cosworth USA and a set of OEM gaskets from the dealer. The passenger's side secondary valve and air-feed tube are not easy to work on. The valve is located next to the driver's side valve and is tucked half-way under the intake manifold. The air-feed tube is also snaked along the top of the engine block under hoses and wires. To access the bolts to the air-feed tube on the passenger's side head you do have to remove the downpipe and the uppipe. Luckily the uppipe can be removed in its entirety without having to remove the header collector or jacking up the engine. I also highly recommend getting new OEM gaskets when reinstalling the exhaust pipes. Also use anti-seize on the bolts as well. Instead of trying to get the entire air-feed tube out, which would have been more work, I left it in place. I used a hack-saw blade that I cut in half to cut the head off the air-feed tube. As previously stated by others you have to watch that you do not cut into the power-steering line or the turbo oil-feed line. After the car was back together, it started and ran without any problems what-so-ever. I of course had a CEL and the cruise-control indicator lamp flashing. I took the car up to my tuner and he simply took my Accessport and downloaded my original map he previously created from my original tune. He created a new map for me that omits the air-feed system. No CEL and the car runs like a champ. Honestly, I did not know if either secondary valve was actually failing. I took an educated guess using this post in part as a guide. I was correct in doing so. No more exhaust feed-back noise and overall the car is a bit more quiet. My feeling is that the valve never fully closed. Regardless, it's out. When I eventually get around to servicing the intake manifold and TGV's, that's when I will remove the passenger's side secondary valve and air-feed tube. Plan on spending a good part of the day doing this install. |

In fact there will be more power loss using the air pump because the closed loop system is not 100% efficient. . . Engine drives the alternator which then drives the air pump. . . There's 2 couplings in that loop that are not 100% efficient: 1) engine coupled to the alternator 2) alternator coupled to the air pump I'm doing surgery on my car soon when I drop in my newest turbo and I remember how much clutter there is under the IM from my first turbo swap and I'm estimating the issues with removing the air valve on the passenger side next to the turbo inlet. But today I found that Subie put the sensor in that very valve I want to take off. Aye carumba, and damn you to hell Subaru!! |

Do the block off plates really make a good seal?
I would think you need some kind of gasket for them. Plus, if I understand correctly, the valve for this system is part of what gets removed, which means exhaust wants to escape from these "blocked off" holes. That's a leak before a sensor. Also... assumings the holes do get a tight seal, why would the car need a retune if this is the only mod? Or does the tune remove the air pump factor (which is usually not on) |

I'll rephrase my post.
On 07 STI I removed the entire air pump system. I will get a blocking plate and the car will be tuned opensource or with cobb op. will I be having issuies? |

Stupid question:
The guy who is about to do my clutch is suggesting I remove this air pump etc. now ( while working on clutch) because "if" it fails it will be hugely expensive to work on it then. The Air pump works fine. Not sure about the failure rate of these things... Would it work just as well to turn off all the poteintal cells and leave the whole works in place? Thanks |

Okay, so if the air pump dies. Can the cells just be canceled and call it a day, without having to remove everything (pump, solenoids...)?
The relation to the clutch: He says he is down there anyway so this would be a good time to remove the airpump etc. Thanks |

On your car, there are three components that can go bad - the pump and two valves. If the pump craps out or a valve is stuck closed - no problem, disable that CEL and keep on truckin.
However, if a valves sticks open or leaks, you're SOL. If you do have him remove the system, make sure he leaves the valve with the pressure sensor plugged in. I removed all the piping to the valve, but left it in place. DO NOT have him just remove the pump. |
