So, I have a 91 mustang gt, and I checked out my throttle body today only to find that it was absolutely filthy, I cleaned it and noticed a significant amount of the stuff in there seemed to come out of the tube that leads from the throttle body to the oil filler neck, so, if I'm not worried about emissions, can i just cap off the throttle body side and put a breather filter on the oil filler neck side? Or should I just keep the line there? Thanks

If the engine is still fuel injected with MAF, you should leave it connected. Otherwise you will be pulling air through the pvc that is not being metered by the MAF. And that can open a can of worms for the fuel delivery system and how the computer controls things.
