No, he isn't. There is no PCV valve in the ordinary sense. There is a
small orifice, about 1/16" diameter (very roughly) that meters the
crankcase vacuum. This is what gets plugged. Pull the plug out of the
valve cover and have a look see.

Hi Jeff,
They plug with carbon, within a couple thousand miles of an overdue
oil change or the use of a cheap gasoline that doesn't use the PCV
cleaning additives like used with the major gasoline companies. You may
see how this old Carter AFB is completely clogged up at the primaries,

Hi Dave,
There was a factory recall on the that little electrically
controlled orifice, they could all be converted to Positive Crankcase
Ventilation valve, like done on this YJ:

Wow, are you using RTV on it and not letting it cure for the required 24
