Comments : The oil pressure relief valve (or relief valve) regulates the pressure within the engine's lubrication system by automatically opening as soon as a safety threshold is exceeded to return excess oil to the system. Used on competition models and motorsport derivatives, such as the Porsche 911 RSR 2.8, 911 RSR 3.0 and Porsche 914-6 GT, this mechanism maintains stable oil pressure, particularly at high engine speeds. This prevents damage to the seals in case of overpressure, protects the oil coolers and ensures the reliability of the high-performance engine by ensuring optimal lubrication.
