Did some research tonight and found out what the problem is.

I have a RWD TVIS manifold with a FWD throttle body. The problem lies here:

The breather nipple for the head is blocked off where it meets the throttle body. It doesn't go directly into the air chamber by slightly diverts towards the throttle body.

With the FWD 16V 4A-GE's the channel is on the opposite side, so a common fix to this is to install a catch can with a filter hooked up to it.

Or another more laborious route would be to "cut and shut", pretty much get a FWD manifold and cut off one side, weld it shut, and fabricate my own throttle plate.

Also, I can drill into the throttle body and create a new channel to mate up to the RWD manifold.

All these are perfectly fine to do just depends how I want to fix it.

I decided to just install a catch can (yay)
