Mazda MX5 Miata PCV Replacement Guide [1990-2005]

Mazda MX5 Miata PCV Replacement Guide [1990-2005]

This video is the COMPLETE guide to replacing or upgrading the PCV valve on your Mazda MX5 Miata. This guide shows you how to remove your PCV valve and replace it. Also, I go through all the required tools and techniques you might need for this easy DIY job. I upgraded my PCV valve to one off a Mazda 323 Turbo since they’re more suited for boost than the stock Miata one. Either way, the process of removal and installation is the same!

They made this job on the NC a pain in the ass. Every car I’ve had it’s been as easy as this video pretty much. No idea why they designed the 2.0 where the intake needs to be removed.
