Features of Positive Crankcase Ventilation Valve 1. Regulates Crankcase Pressure: It automatically meters the flow of gases from the crankcase back into the intake manifold, preventing a dangerous buildup of pressure. 2. Removes Harmful Blow-by Gases: It efficiently evacuates unburned fuel, exhaust gases, and water vapor that leak past the piston rings (blow-by) from the crankcase. 3. Prevents Oil Leaks and Seal Damage: By maintaining optimal crankcase pressure, it protects engine seals and gaskets from being forced out, which can cause oil leaks. 4. Excellent Chemical Resistance: ABS material offers high resistance to oil, fuel, and other automotive chemicals, ensuring long-term durability and integrity. Effects of Failed PCV Valve 1. Increased Crankcase Pressure: Causes oil leaks from engine seals and gaskets. 2. Sludge Formation: Allows moisture and corrosive acids to build up in the oil. 3. Poor Engine Performance: Results in rough idling, stalling, and hesitation. 4. Higher Oil Consumption: Forces the engine to burnong excessive oil, leading to blue smoking from the exhaust.
