Does anyone know where this(circled in red) port connect to?

I pulled the engine from the car a few months back and due to bad labeling I don't know where it connects to.

 

I think PCV hose to valve cover if memory serves me correct.

 

Yep, thats where the PCV from the back of the valve cover connects

 

Thanks!

Thanks!

Since I'm not using the PCV and going to a catch can, can use that port for a vacuum block?

 

You could technically use that as a vacuum source however even if you dont use a PCV depending on your CC setup you still could possibly use that nipple regardless. The difference would be simply that the CC is in line vs just a straight hose to that nipple.

If you plan to have a VTA CC then most people just cap off that nipple so in your case you could instead use that as a vacuum source.

 

Cool, thanks!
