- Sustained Generator Output — A properly functioning separator keeps the engine's air supply clean and free of oil contamination, protecting combustion efficiency and consistent power delivery.

The Separator A/C is responsible for separating oil mist from the air-oil mixture that passes through the engine's crankcase ventilation system. By capturing and returning oil before it can enter the air intake, it prevents oil from being burned in the combustion chamber, which would otherwise lead to increased emissions, fouled spark plugs, and accelerated engine wear. When the separator becomes clogged or degraded, oil consumption rises and engine performance drops — making timely replacement essential to keeping the GPSi4300 running cleanly and efficiently.
