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.
To effectively diagnose a vacuum leak in your 2013 Hyundai Azera, start by checking for any trouble codes using an OBD-II scanner. This initial step can help pinpoint specific issues related to the engine's performance. Next, listen carefully for any unusual sounds, such as hissing or whistling, which often indicate a vacuum leak. Pay particular attention to the area around the engine, as these noises can guide you to the source of the leak. Additionally, inspect the exhaust system, especially near the B1S1 O2 sensor, as leaks in this area can contribute to vacuum issues. By following this diagnostic approach, you can systematically identify and address potential vacuum leaks, ensuring your vehicle runs smoothly and efficiently.
When tackling vacuum leaks in a 2013 Hyundai Azera, it's essential to understand the various problems that can arise. One of the most noticeable signs is the illumination of the check engine light, often accompanied by the P0171 code, which indicates a lean air-fuel mixture due to excess air entering the engine. This condition can lead to engine misfires if the air-fuel ratio strays from the ideal 14.7:1, potentially affecting performance without immediate drivability issues. Additionally, vacuum leaks can significantly impact fuel economy and emissions, as unmetered air disrupts the air-fuel balance, leading to increased fuel consumption and higher emissions. Identifying the source of these leaks can be tricky, as they may not always produce audible hissing sounds and can be mistaken for other engine problems. Common culprits include cracked or broken vacuum hoses, which are relatively easy and inexpensive to replace. However, more severe issues, such as a cracked intake manifold, can lead to costly repairs. Understanding these common problems is crucial for timely detection and repair, ensuring your Hyundai Azera maintains optimal performance and efficiency.
