Overloaded and trimmed engines produce a lot of overpressure in the crankcase, which needs to be vented. Vapours from crankcase overpressure contain oil mist, which can dirty the engine and lower the octane rating if the mist is led back into the intake. A well-ventilated engine is not as likely to leak oil as a poorly ventilated engine. NOTE Filter for crankcase ventilation, should for environmental reasons, only be installed for car shows and competitions.
