breather venting

I am running the screaming eagle forward facing heavy breather. 29006-09b on a 2016 SGS Stage 1 kit.
I am trying to research how to run a catch can off this breather. From what I can tell the bolts 29465-08 are what is venting the case. However, they don't really appear to vent anywhere or lead back into the breather.
Does anyone have experience with this that could possible provide me with any information.

Thanks in advance.

If you pop the two caps off you will see a passage way going to the throttle body, the bolts are hollow.

Thank you! Then essentially its not venting anywhere? The caps air lock the housing the bolts are in. So everything just goes back into the head?

I pulled the breather off and had some thick milky oil in the face of the throttle body.

I pulled the caps off and there was a small amount of milky oil in the housing. It must just settle in there until you clean it out. It appears that once it has made its was through the hollow bold it does not get re introduced into the throttle body.
So my assumption, there is no need to run a catch can as this system is basically a catch can?

Thanks for the help. If anyone has more info and I am missing something please let me know.

Not all the milky crap is just staying in the throttle body. You need to vent it somewhere else.

There are two conduits from the breather bolt standoffs that run to the throttle body opening. They most definitely vent to the intake. If they didn’t you’d be blowing seals due to the crankcase overpressuring.

To vent externally you will need to plug those passageways, drill a hole at the bottom of the breather bolt standoffs and install some hose barbs to run fuel line (oil resistant) to wherever you want to vent to.
