The regulated engine crankcase gas filter is a cylindrical reactor vessel connected to a positive crankcase ventilation (PCV) valve tubing to eliminate formed particulates from the gaseous material by increasing the volume in an expansion chamber to increase gas expansion formed and filtering out the particulates by a stainless steel mesh filter. The cleaned gas flows into a vortex creating nozzle and atomizing chamber, then through a metering jet or a metering washer, so that a fine gas mist exits the filter to the engine intake air system. An access port is available to check and maintain the functional aspect of the filter. The check-ball plug or check plug containing the filter medium, i.e., the cotton, can be changed as needed. The check-ball plug provides a means for outside air to mix with the inside gas molecule on demand.
