Decided to buy a new pcv orfice in case I wanted to revert back to stock following the 7/64" drill mod. I noticed there's something inside the orfice tube. I can hear it rattle and if I hold the single hole end upside down something will show in the hole. Appears to be nylon type matierial. I'm wondering if it modifies airflow depending on vacuum level? Any case strange.

Probably oil buildup. There wasn't anything in mine when I did the mod I could see straight through it. Trust me if you are having oil blowby into your intake tube you won't convert back. Did mine 3500 miles ago and haven't had 1 drop of oil in the intake since.

This was the new orfice that had something inside. Whatever it is doesn't restrict sticking a small wire thru the unit and out either of the holes in the bottom.
