what is this on classic manifold?
On the weekend a friend and I were working on his 97 impreza. We saw this on the intake manifold but dont know what its for. a hose of some sort should be connected to it. when engine is running, placing a finger on top of it feels like a vaccum, and idle is lower. release it and the idle rises a bit
whats this for? and if it should be connected to something, where to? http://img.photobucket.com/albums/v3...e/DSC00002.jpg |
I think it can be used for a boost gauge pipe, Mine has already got a pipe on it so :confused: at the moment.
|
It's a pressure take off point, it should be connected to something or it should have a cap on it to blank it off. It defentally shouldn't just be open like that. My car has a different inlet manifold so I don't know exactly what that one is for. But someone will.

I say you want to block it off pronto, unfiltered air ! Took my boost gauge hose from there, should have blind end tube on it.
|
It usually connects a pipe that runs to the purge control solenoid valve.....
|
Its was blanked off on my 97uk scoob with a black rubber cap. Get some tube for over it and crimp the end for the time being.

My boost guage feeds off it but it has a t pipe off it dont know what the other pipe is for.

thanks all for input |
or maybe I should just block it
|
Yeah the boost solenoid valve goes to 1: The t peice between the turbo outlet and the wastegate actuator. 2: the in inlet manifold.
The purge control solenoid connects to the one were on about, if you don't want the purge system then just block it. |
