Possibly the core to a pcv valve? Check the one on the engine, look for a spring that fits around the outside of that-catches on the flange on the big end. If it has been replaced you don't know if the spring is sitting in the engine somewhere.
I'll just take the valve cover off before starting it up to see if there's anything else in there. I never saw any spring, and there wasn't anything on the outside of the PCV valve, so I assume you mean something else from inside the valve? Either way, better safe than sorry.
