its kinda a dumb question but im about to boost my gsr and will be running a catch can to the back of the block. therefore eliminating the pcv system.. this will leave an open port on the top of my Blox intake manifold.. my question is how do i plug or cap the port. i dont want it blowing off under boost.

 

cmon people

 

how do you plug it

 

use it for a vac source or rubber cap and clamp it.

 

do i not have to split the main line now and can run my vacuum block off that open intake manifold port alone
