so i took my UIM off last night and put it back on. i went to start her and she revved to 3K and then just died on me... i knew it was a fat vac. leak, but where? ahaaa! i found it!

i'm guessing it's just some sort of check valve? where can i get one? an auto parts store? it's split right in the middle so i can't use it.

the pics show where the line starts and ends, and what it looks like

 

Thats part of your cold start function, correct me if im wrong, but i belive you can just remove that system.

 

The green thing in the second picture is a check valve. They all are typically removed when doing a throttle body modification (i think the other one is a dash pot).

thanks guys.. i'll be removing all of this stuff on my s5 TII when i put it in, but for right now, i don't even wanna remove the cold start or anything, so i just bought a check valve from o'riellies.

damn i hate all this emissions crap! all of it will be BURNING IN HELL SOON!

(where's that devil smiley???)

 

One way check valve? Once emissions are all gone this is no longer needed.
