Positive crankcase ventilation

If they are not inspected, have at it! My 82 Mazda had to pass a visual (all smog parts intact, although I plugged the inlet of a blown vacuuum pot as there were no spares available) as well as a dyno idle/15/25 mph 'loaded' sniffer test. Darn fuel pump was weak/filter plugged and it leaned out on the 25mph load test and could not maintain the RPM window. ...FAIL!
