Abstract
A blowby mist separator and regulator system for an enclosed crankcase of an internal combustion engine having a submicron mist separator and vacuum regulating valve disposed in a horizontally oriented cylindrical housing connected in fluid communication with the crankcase and an air intake manifold to maintain a vacuum within the crankcase, continuously return separated coalesced mist to the crankcase and prevent cylinder blowby from escaping to the atmosphere and having a pressure sensor in the crankcase, which cooperates with a high pressure indicator to indicate when the pressure within the crankcase becomes positive and blowby gases could be released into the atmosphere if the mist separator is not replaced.
