Rough idling, lack of power, engine oil leaks, engine burning oil, and illumination of the check engine light are all possible if the PCV valve has clogged. If the check engine light comes on, the on-board diagnostics (OBD) trouble codes will most likely relate to manifold vacuum, air and fuel mixture, PCV system, mass airflow sensor readings, and exhaust and emissions readings. These are all affected in the event the PCV valve is clogged, is stuck fully open, or is stuck fully closed, however, if the valve is stuck fully open, the engine oil seals are not in danger of overpressure.
A bad valve cover gasket will result in an oil leak. You may notice oil under the car or on other parts under the hood. You might also notice a burning smell while driving.

Any time there is an emissions fault the check engine light will be displayed. The purpose of the check engine light is to inform the driver that an emission related fault has been found, and that there are on-board diagnostic (OBD) trouble codes stored in the powertrain or engine control module. Additionally, since the emissions systems are so intertwined into engine control and transmission control systems, symptoms may include nearly any sort of drivability concerns. This may include harsh shifting, failure to shift, hesitation on acceleration, jerking, engine failure to start or run, loss of power, or any number of other drivability issues.
When troubleshooting vacuum leaks in your Dodge Avenger, start by inspecting the most accessible components, such as vacuum hoses and connections. Look for any visible cracks or disconnections, as these are common culprits. If you notice any damaged hoses, consider cutting the affected area and securing it with a zip tie as a temporary fix. Next, pay attention to gaskets and seals around the intake manifold, as these can also lead to leaks. If your vehicle exhibits symptoms like rough idling or stalling, it may be beneficial to check for diagnostic trouble codes, particularly the P0441 code, which can indicate issues with the leak detection system. For a more thorough investigation, use a simple method like spraying shaving cream around the intake area; this can help reveal leaks by observing any changes in the cream's behavior. By following this diagnostic approach, you can effectively identify and address vacuum leaks, ensuring your Dodge Avenger runs smoothly.
When dealing with a vacuum leak in your Dodge Avenger, it's essential to recognize the common problems that can arise. Symptoms such as rough idling, decreased fuel efficiency, and the illumination of the check engine light often indicate a vacuum leak. These issues can stem from various sources, including cracked or disconnected vacuum hoses, which are crucial for the proper functioning of the EVAP system. Additionally, the intake manifold, power brake booster, and PCV system are frequent culprits that may develop leaks over time. If you encounter trouble codes like P0441 or P0443, these can point to specific failures in the leak detection pump or vacuum hose connections. To address these problems, start by visually inspecting all vacuum hoses for damage and ensuring they are securely connected. If you suspect a leak, a simple test involving a spray of soapy water on suspected areas can help identify the source, as bubbles will form where air escapes. By understanding these common issues and their solutions, you can effectively diagnose and repair vacuum leaks, restoring your vehicle's performance and efficiency.
Fixing a vacuum leak in your Dodge Avenger is not just a matter of convenience; it is essential for maintaining the vehicle's performance and safety. A vacuum leak can lead to a range of problems, including poor engine performance and erratic air conditioning operation, particularly when accelerating. If these symptoms are ignored, they can escalate into more severe issues, such as decreased fuel efficiency and potential damage to critical engine components. The urgency of addressing a vacuum leak cannot be overstated, as neglecting it may compromise the overall health of your vehicle, leading to costly repairs down the line. By promptly identifying and fixing a vacuum leak, you not only enhance your car's performance but also ensure its longevity, making it a vital DIY task for any Dodge Avenger owner.
