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 INFINITI Q60, begin by inspecting the most common culprits: the vacuum hoses. Look for any visible cracks, tears, or disconnections, as these are often the easiest and quickest fixes. Next, examine the intake manifold and throttle body gaskets for signs of wear or damage, as leaks in these areas can significantly impact engine performance. If the initial checks do not reveal any issues, consider the PCV valve and its associated hoses, which can also contribute to vacuum leaks. Pay attention to the symptoms your vehicle is exhibiting, such as a high idle or irregular engine performance, as these can guide you to the source of the leak. By methodically assessing these components, you can effectively identify and resolve vacuum leaks, ensuring your INFINITI Q60 runs smoothly and efficiently.
When diagnosing and fixing a vacuum leak in your INFINITI Q60, it's essential to be aware of the common problems that can arise. One of the most frequent culprits is cracked vacuum hoses, which can deteriorate over time due to heat and exposure to engine fluids. These cracks often lead to a noticeable drop in engine performance, including rough idling or stalling. Additionally, leaking intake manifold gaskets can create similar symptoms, as they disrupt the air-fuel mixture necessary for optimal engine function. Less commonly, issues may stem from the throttle body gasket or even a cracked intake manifold, which can be more challenging to detect. Symptoms such as a check engine light, increased fuel consumption, or unusual engine noises can indicate a vacuum leak. By understanding these common problems, you can better diagnose the issue and take the necessary steps to restore your vehicle's performance.
Addressing a vacuum leak in your INFINITI Q60 is not just a matter of routine maintenance; it is an urgent necessity that can significantly impact your vehicle's performance and safety. A vacuum leak disrupts the delicate balance of air and fuel in the combustion process, leading to engine performance issues such as rough idling, stalling, or decreased acceleration. Common culprits like cracked hoses or a faulty intake manifold gasket can exacerbate these problems, and if left unchecked, they may result in severe engine damage or failure. Moreover, vacuum leaks can compromise critical components like the brake booster, affecting your vehicle's braking efficiency and overall safety. Therefore, promptly identifying and repairing any vacuum leaks is essential to maintain the optimal functioning of your INFINITI Q60, ensuring not only a smooth driving experience but also the longevity of your engine. Ignoring these symptoms can lead to costly repairs and safety hazards, making it imperative to act swiftly.
