Replacing PCV and Purge Valves

I described the Miata’s valve cover gasket replacement earlier. At the time I had not replaced the PCV valve, however, now that the car has aged further and received a code P0106, I chose to change both the PCV valve and the purge valve. This post describes the changes. I chose not to change the boost solenoid, which is also recommended for fixing the P0106 code.
