PCV VALVE CRANKCASE VENTILATION. The Positive Crankcase Ventilation valve is a component of the engine crankcase ventilation system designed to route blow-by gases from the crankcase back into the intake manifold for controlled combustion. During engine operation, combustion gases leak past piston rings into the crankcase creating pressure and contaminating engine oil. The PCV valve regulates gas flow according to intake manifold vacuum, preventing excessive crankcase pressure, oil seal leaks and lubrication degradation. The assembly may consist of a spring-loaded check valve, diaphragm regulator or integrated module within the valve cover including an oil separator. Operating principle is based on metered gas recirculation under varying engine loads to maintain stable air-fuel mixture and reduce emissions. Failure symptoms include increased oil consumption, unstable idle, crankcase pressure buildup, oil leaks, sludge formation and diagnostic fault codes. Causes may involve valve sticking, diaphragm rupture or clogging due to oil deposits. Our catalog includes genuine OEM PCV valves, quality aftermarket replacements and inspected used units free from cracks or membrane damage. Used parts are checked for sealing performance and proper valve movement. Selection is based on VIN number, engine type and part number. Timely replacement ensures proper engine operation and emission control compliance.

Additional information

PCV valve by GM, OEM 55568910, is a component that works within the engine or its auxiliary systems and supports normal operation. The source data describes this item as “Клапан PCV вентиляції картерних газів”. Correct operation of this part supports the related assembly and the vehicle functions designed around it. Wear may show as unusual noise, oil or air leakage, unstable engine operation, reduced power, increased consumption, or diagnostic faults. A single symptom does not always prove that this exact component has failed, so power supply, wiring, mountings, or adjacent parts should be checked as appropriate before replacement. Before purchase, compare the OEM number, engine code and revision, identification marks, dimensions, mountings, and adjacent-part configuration. OEM 55568910 is the primary reference, but an identical product name does not guarantee compatibility across different vehicle specifications. Before purchase, compare identification and appearance with the old part and verify compatibility by VIN.
