PCV valve failure cause

Hi all, my PCV valve is bad and is making that squealing noise. I do not have a tune but I have downpipes, a midpipe, intakes, and chargepipes. Could these mods that probably add like 30-40 horsepower have contributed to the PCV going bad? I’m wondering this because I’m trying to see if it is covered under my extended warranty, I wouldn’t be taking it to the dealership, I would be taking it to an independent guy who won’t say an intake voids warranty. Thanks
