On this Jeep CCV system, no vacuum is present at the air inlet hose located toward the front of the engine rocker arm cover. Instead, crankcase blowby is constantly coming from this hose into the air filter. A strong vacuum is felt at the hose connecting to the fixed orifice fitting at the rear of the cover. Since the fixed orifice is apparently clogged, how does one clean this fitting?
