The PCV valve is part of your engine’s emission control system. The full name is “Positive Crankcase Ventilation Valve” and it allows the air pressure inside the engine block to be controlled. As the pistons move up and down their cylinders, pressure builds and must be vented. This is different from the pressure inside the cylinders caused by combustion which powers your vehicle. Crankcase pressure is made up of several glasses. Fresh air is drawn into the lower part of the engine. This air also contains water vapor, oil fumes and minute bits of burned combustion gasses. The PCV valve allows the gasses to vent through the air filter, and they are burned and passed through the exhaust system. The entire process is designed to prevent excessive pressure to build up inside the lower part of the engine.
PCV Valves require periodic replacement according to the schedule listed in your owner’s manual. As part of regular service, your dealer will alert you when this maintenance is required. The valve will need to be replaced, as it is a sealed unit that cannot be cleaned. PCV Valves that are not replaced as part of regular maintenance cause a number of problems.
These parts are relatively inexpensive. The average cost is between $20 to $35. Labor costs can be $80 to $100. The cost of ignoring this maintenance is much higher because of increased fuel consumption. Rough running due to a dirty air filter that has been clogged by a malfunctioning PCV Valve will waste fuel and can even cause engine damage. If you experience any of the symptoms listed above, call your Chrysler Dealer as soon as possible.
