The valve itself should rattle when you shake it to know it is functioning. If it is leaking oil from around the seal, then I guess you would have to replace it.

BTW: Cool avatar.

If oil is coming from around the PCV valve it may be something else. Could be the gromet it mounts in, or internal egnine issues.

check the obovious, cracked rubber gasket, stopped up pvc valve.

But you should be getting a good solid vac on the pvc line back to the carb.

The pvc valve on my 84 4 banger is tee off to the brake boster.

be sure the other hole in top of valve cover (incoming air) is not stopped up and you are getting clean filter air into the valve cover. The air that goes to my valve cover comes from a connection inside the carb air filter. so the air going to the valve cover is clean filtered air.

If all is working properly you should have so much vaccum pull that you should not be getting much oil leakage.

so check your vac pull.
