However, it was not until the engine’s crankcase was fitted with a vent or evacuation tube that major improvements were experienced.įirst there was nothing more than plain breathers to allow excess crankcase pressure to be released or vented. The addition of these breathers resulted in moderate engine life improvement. In the past, engines were equipped with breathers that would allow the crankcase to “breath”. If these contaminates are kept inside the combustion chamber, they will eventually make their way into the oil inside the crankcase and cause oil contamination and dilution or make their way back into the intake manifold. Condensation is more susceptible in humid climates, but it can exist anywhere there is fluctuation in temperatures in a hot to cold environment. In addition to the air/fuel mixture and oil mist, there’s also the possibility of condensation, or water droplets. Since the oil catch cans condense the vapor portion of the gasses, they will need to be drained periodically of all the oil, fuel and other contaminants. Typically the blow-by gasses are passed through a wire mesh, which give the vapor droplets something to adhere to.

Some of the oil mist and other products settle along the engine intake and over time form a “gunk.” The oil catch can collects the oil mist and condenses the fuel vapors while allowing “cleaner” gases to be passed back into the intake.

This leakage is often referred to as “blow-by” (leakage past the piston rings), as well as oil mist. A small amount of that ignited mixture leaks past the piston rings and ends up in the crankcase. It’s a way for gases to escape in a controlled manner from the crankcase of an internal combustion engine.ĭuring normal operation of an internal combustion engine, there’s a compressed air and fuel mixture inside the combustion chamber that is ignited and as a result, forces the piston down.

The PCV (Positive Crankcase Ventilation) system is designed to regulate and remove fumes from the engine crankcase, and to alleviate crankcase pressure which could cause oil leaks or seal damage.
