To maintain the optimum performance of the oil separator, keen focus should be directed on its operations with no compromises. Starting from general rounds, housing checks, examining baffles, and filter media to heartbeat checks, all have to be in top shape with no leaks, blockage, or damage whatsoever. Cleaning of the separator’s oil drain should also be done to prevent overflowing of separated oil. Depending on the type of oil separator, further action might be needed in the form of filter media cleaning, replacing, or unclogging overdue filters. A properly maintained oil separator prolongs the operational lifespan of the engine’s auxiliary components as oil is efficiently removed from the crankcase gases.
