PCV replacement

Post a photo of the bottom of the part that was stuck in the gasket.

My guess is that all of the parts displayed came out when it broke, and only the plastic stuck part was left, correct?

Correct. Here the photos (bottom piece + spring)
I compared with the new valve and i don’t see how it’s possible that something fell inside.
Btw, i bought the car few weeks ago and it looks like the valve was broken since a while. The previous owner tried to seal both pieces with something with no success...
