I began the project to port my throttle body some 20 minutes ago and I'm having difficulty getting this last toe hose off. I'm wondering if I should disconnect it from the TB at the point circled in red or black. Note that oil dripped out of the opening circled in yellow.

If I disconnect from the TB at the red point, will oil flow out uncontrollably? And does oil flowing from the yellow point indicate a seal leak somewhere?
Thank you much!

PS: My car is a 2001 ls1 vert

 

It's not oil, i believe thats a coolant passage.. im not sure how it's done but i'm pretty sure some people are bypassing that somehow. Worth looking into.. Since you already removed the yellow, why dont you just disconnect the black, looks like the only thing holding it up.. "black and yellow, black and yellow"

 

Yep its a coolant line to warm the air through the tb. It is a common mod known as the throttle body bypass, not worth much in terms of power though.
