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 2017 Volvo XC90, start with a thorough visual inspection of the vacuum hoses. Look for any signs of damage, such as cracks or loose connections, which are often the culprits behind leaks. Once you've completed the visual check, start the engine and listen carefully for any hissing sounds that could indicate escaping air. If you suspect a leak but can't pinpoint it, using a smoke machine can be highly effective; it introduces smoke into the system, allowing you to see where it escapes. Alternatively, you can spray a mixture of soapy water on the hoses and connections while the engine runs; any leaks will produce bubbles, making them easier to identify. For a more precise assessment, consider using a vacuum gauge to measure the vacuum levels in the system; a drop in pressure can signal a leak. Don’t forget to inspect the intake manifold gasket and the brake booster, as these are common sources of vacuum leaks. If your efforts do not yield results, consulting a mechanic may be necessary for a comprehensive diagnosis and repair. This step-by-step approach not only simplifies the process but also empowers you to tackle the issue with confidence.
When tackling the issue of a vacuum leak in your 2017 Volvo XC90, it's essential to recognize the common problems that can arise. One of the primary culprits is worn-out hoses, which can deteriorate over time, leading to cracks and leaks that compromise the vacuum system's integrity. Additionally, faulty vacuum fittings can create loose connections, resulting in air escaping where it shouldn't. Another significant concern is a damaged intake manifold gasket, which can disrupt the vacuum seal and cause performance issues. If the vacuum pump is malfunctioning, it may not generate the necessary suction, further contributing to leaks. Lastly, keep an eye out for cracked or broken vacuum lines, as these can also lead to significant air loss. Symptoms of a vacuum leak often include a rough idle, decreased engine performance, and the illumination of the check engine light, along with potential hissing noises from the engine bay and hard starting issues. By understanding these common causes and symptoms, you can better diagnose and address vacuum leaks, ensuring your Volvo XC90 runs smoothly and efficiently.
Addressing a vacuum leak in your 2017 Volvo XC90 is not just a matter of routine maintenance; it is a critical step in ensuring the safety and longevity of your vehicle. A vacuum leak can lead to serious performance issues, including rough idling and stalling, which can compromise your ability to drive safely. Additionally, if left unaddressed, a vacuum leak can result in poor fuel efficiency and engine misfires, ultimately leading to more extensive and costly repairs. The longer you wait to fix this issue, the greater the risk of causing damage to other engine components, which can escalate repair costs and affect your vehicle's overall performance. Therefore, it is essential to prioritize the repair of a vacuum leak to maintain your Volvo XC90's efficiency and reliability, ensuring a safe driving experience.
