Hey guys!! I was replacing my valve cover gasket and broke a little part. I have no idea what it is called and was hoping for some help. This is a 99 Kia Sportage 4x4 with manual transmission. Thank you in advance. She is my daily driver so I need to get her "Mud" put back together asap!! ☺

Nothing like HIJACKING an already well taken care of thread. This is NOT helpful to the original poster or others that may come searching for the same original problem later. Take this theory debate to a new thread in the off topic page.
seemed relevant to the pcv to me, which was half the thread
Air entering the intake manifold through the PCV system is unmetered because its after the MAF, but on models that use MAP's it would not be an issue.

Visualize at idle the pistons on their intake stroke are sucking air against a closed throttle butterfly causing high vacuum in the intake manifold, and with wide open throttle the intake manifold will be at atmospheric pressure.

The intent is to keep just a slight vacuum on the crankcase.
Didn't think the flap was closed that tight myself, but I appreciate your response, nor did I think about the MAF MAP. Always appreciate understanding the systems in depth.
