Operation: PCV valve cleaning instructions

The movement of the air under the cylinders allows the oil to be injected more quickly on the walls of the cylinder, but it can modify the direction and the quantities per side, for this reason to have an even better efficiency both in lubrication and in yield. thermal, in sports engines the crankcase is depressurized (0, 4 atmospheres below atmospheric pressure, equal to 1). This depressurization can be obtained by releasing the air, using specific machinery or if the engine is not multi-fractionated or without windows, a special "PCV" (Positive crankcase ventilation) valve can be used, which lets the air escape. , when this is too compressed and avoids its reflux, so as to have a lower and lower pressure when the piston rises or through recovery pumps. The air that comes out of the valve is contaminated by oil vapors and unburned fuel and therefore can become clogged, losing efficiency and therefore must be cleaned or replaced if necessary. On the car model in question, the valve is located in the front left part of the crankcase and it is necessary to disconnect the sleeve in order to then be able to unscrew it.
