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 INFINITI M56, begin with a thorough visual inspection of all vacuum hoses and connections. Look for any signs of wear, such as cracks or loose fittings, which are common culprits for leaks. Next, start the engine and listen carefully for any hissing sounds that could indicate escaping air. If you suspect a leak, using a vacuum gauge can provide valuable insights; connect it to the intake manifold and monitor for fluctuations in pressure. For a more hands-on approach, perform a spray test by applying carburetor cleaner or propane around the hoses while the engine runs; a change in RPM will signal a leak. If these methods do not yield results, consider a smoke test, which involves introducing smoke into the intake system to visually identify leaks. Lastly, don’t forget to check for any trouble codes using an OBD-II scanner, as these can provide additional clues about potential vacuum issues. By following these steps, you can systematically diagnose and address vacuum leaks, ensuring your vehicle runs smoothly.
Understanding the common problems associated with vacuum leaks in a 2013 INFINITI M56 is crucial for any DIY enthusiast aiming to maintain their vehicle's performance. One of the primary causes of a vacuum leak is damaged or deteriorated vacuum hoses, which can crack or become loose over time, allowing air to escape. Additionally, a faulty intake manifold gasket can lead to significant leaks, as can cracked or damaged vacuum fittings. Another potential issue is a malfunctioning throttle body, where a faulty gasket or seal may disrupt the vacuum system. Symptoms of these leaks often manifest as rough idling, decreased engine performance, and unusual hissing or whistling noises from the engine bay. Furthermore, the check engine light may illuminate, signaling a disruption in the engine's vacuum system. By being aware of these common causes and symptoms, DIYers can take proactive steps to diagnose and address vacuum leaks, ensuring their INFINITI M56 runs smoothly and efficiently.
Addressing a vacuum leak in your 2013 INFINITI M56 is a matter of urgency that should not be overlooked. While it may not seem like an immediate emergency, the implications of ignoring a vacuum leak can escalate quickly, leading to rough idling, stalling, and decreased fuel efficiency. Over time, these issues can contribute to more severe engine damage, resulting in costly repairs that could have been avoided with prompt attention. For DIY enthusiasts, understanding the signs of a vacuum leak—such as unusual engine sounds or fluctuating RPMs—can empower you to take action before the problem worsens. Regularly inspecting hoses and connections for wear and tear can help maintain your vehicle's performance and reliability. Ultimately, addressing a vacuum leak swiftly not only preserves the health of your INFINITI M56 but also enhances your driving experience, making it a crucial task for any car owner.
