How to test for bad PCV?

Hey guys i did some research and there seems to be multiple ways to test a bad PCV but i am still confused as to what signs to look for. So far i tested by:
  1. Start engine leave it idling, remove engine oil cap, engine starts sputtering and vibrating pretty hard.

Does this mean that my PCV is still good?
