Default B18 Vacuum Diagram, for B20v

Alright guys, I've got some idle issues, so I'm going through the process of eliminating things one by one.

While I wait on some parts to come in, I figured I'd inspect my vacuum layout. As a note, I have deleted my charcoal canister.

Below is my spacial diagram, for us special people.

Does everything look like it's proper?



Thank You!

blue hose should go to evap canister. if your not running one just cap it. dont know how you have your iacv hooked up but the only hoses that run to that are coolant lines.

Only coolant to the IACV? There's a line from the TB to the IACV, it's dry. I figured it was vacuum.

Yup, finally found it. It is just coolant. Looks like the port that feeds the TB has been eliminated, so I'll just cap the TB to IACV coolant ports.

Alright, bare with me here. I found a "block-off" plate in my IACV (foil tape....)

But now I need to ensure that the coolant routing is correct and all the diagrams I've found are quite...Muddled and convoluted.

Here goes my spacial Photoshop. Does this routing look accurate?

What was the end result here? I am struggling myself to find I diagram that shows the vacuum and water lines clearly...its all I need to finish the swap but every diagram I find is too cluttered and hard for me to follow...
