Default PCV Replacement

2014 Mazda3 with about 60k miles.

Wanted to replace the PCV valve as a preventive maintenance item, but it looks like it's going to be a major pain. Is it accurate that I have to remove both the intake manifold AND the oil separator? I assume I should replace those gaskets too? This seems like a LOT of work for a lowly PCV. Any shortcuts?

Intake manifold requires removal.
