PCV Valve Replacement Service

Chrysler, Dodge, Jeep, or Ram PCV Service

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.

Signs of a Malfunctioning PCV Valve

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.

  • Rough Running Engine – If the valve or the hose leaks, excess air will disrupt the precise proportions of air to fuel. The result will be a rough running engine and increased fuel consumption.
  •  Oil Leaks or Excess Oil Consumption – A stuck PCV valve will cause excess pressure to build inside the engine. This will force the oil inside the engine to leak past gaskets, or be forced past the piston rings and be burned.
  • Dirty Air Filter – A stuck PCV valve can allow excess oil fumes and water vapor to pass on to the air filter. Eventually, this will clog the air filter and cause lost power, excess fuel consumption and rough running.
  • Excess Oil Vapors – This can also foul spark plugs. When this happens, they are unable to properly ignite the air/fuel mixture in the combustion chambers.

Cost to Replace A PCV Valve and Hose

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.
