What is this? Broken part.

[haze5736]

I have an '04 SVM, 5 speed with about 74k miles. Can anyone tell me what this part is? And what symptom I should be noticing since the hose is broken? Also, where can you get a factory service manual and how much do they cost?

where is that? it looks like a runner selector? but...

manual is available for free via torrent.

The part is located on top of the engine toward the firewall. I can take another picture tonight, zooming out, to give better perspective.
Can someone point me to a link for the torrent? I was browsing posts last night and all links I found to a FSM were dead.

its "live" but only when i and a few others know to seed it, i've personally got a ratio on it of 15:1.

Yeah, thats the vacuum actuator for the secondary intake runners. It shouldn't cause problems, but it will reduce high rpm power.

Called my dealer parts dept. He said the part is listed as vgis valve solenoid. I have no clue what that is or what it does. Anyway, the new hose is $4.72.

vgis is "variable geometry intake system" which is fancy talk for runner selector.

basically your engine has two intake ports running to each cylinder, a long one and a short one, that piece chooses which one to use for maximum performance..

The part itself doesn't appear to be broken, just rusty. Get yourself a new rubber hose and you should be fine.

I bet autozone has a fine selection of vacuum line connectors to choose from. Same thing is broken on the aveo I am working on

Thanks for posting this. Noticed I have been low on power in the RX car and sure enough the boot was cracked just like in the picture. It's amazing how taught they made this line, considering how much the engine twists in the bay. It's amazing it lasts as long as it does.

A+ poster, would subscribe again.
