If the engine on your car or truck is exhibiting a whistling noise during operation then this could be an indication that the crankcase pressure regulating vent valve is defective. You should very carefully and slowly remove the oil cap when the motor is running. If pressure is released when you remove the cap and the noise discontinues then this component is malfunctioning and requires replacement as soon as possible. You may also acknowledge that the oil has a milky appearance due to condensation created by the pressure within the crankcase. Pressure build up within the crankcase of an engine can lead to extensive damage to internal components. The crankcase pressure regulating vent valve relieves this pressure and routes it to the manifold for combustion.
A crankcase pressure regulating vent valve opens as required to release pressure that builds up within the engine during operation. Pressure is developed through blow by which occurs when pressure passes through the piston rings during the combustion process. The importance of these components increases as the motor ages and wears. As it wears the amount of blow by will increase and the valve will compensate for this condition that will extend the life span of the motor. Increased pressure in the crankcase hinders the lubrication process by removing essential properties from the oil due to condensation in the system.
Replacing a crankcase regulating vent valve is normally a pretty simplex procedure depending on the car, truck, or SUV involved in the task. You may be required to remove some components to appropriately access this device. You should examine the mounting procedures incorporated to determine the removal requirements. Before the installation process you should clean the port thoroughly. After the installation of the new device an oil change is recommended because the oil condition is negatively affected when this component malfunctions.
When procuring a new crankcase regulating vent valve it must meet all of the requirements for the application to function appropriately. You should remember that this component increases the dependability of the motor you rely on daily and quality is essential.
