Not sure what else to call it -- i just got out the Bentley and that's what they have it labeled. (appears to be No. 4 in the image)

anyway, ist all busted up and i have no idea how long it's been that wat. anything i need to fix immediately before driving, or just get done asap? wtf does it do (specifically)?

 

i just blocked that part, does not return to the intake anymore. what kind of problem it cause to you ?

 

i don't know that it's causing any. i was in the process of installing an N75H when I noticed that it's busted wide open. don't know much about it or what it even does.

 

No 2 is the evap purge valve. Number 4 is just a one way check valve. Two will have a couple wires going to it while four will not have any wires.

 

right.

it's replaced now anyway!
