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 diagnose a vacuum leak in your 2020 Mazda MX-5 Miata, 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. Next, start the engine and listen carefully for any hissing sounds that may 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; if bubbles form, you've found a leak. For a more precise diagnosis, consider using a vacuum gauge to measure the vacuum pressure—fluctuating or low readings can signal a problem. Don’t forget to inspect the intake manifold gasket and brake booster, as these areas are common sources of leaks. If your efforts don’t yield results, consulting a mechanic may be necessary for a comprehensive diagnosis and repair. This step-by-step approach not only helps in identifying the issue but also empowers you to take control of your vehicle's maintenance.
When dealing with vacuum leaks in a 2020 Mazda MX-5 Miata, it's crucial to understand the common problems that can arise. One of the primary culprits is worn-out vacuum hoses, which can deteriorate over time due to exposure to heat and engine vibrations, leading to cracks or loose connections. Additionally, a faulty intake manifold gasket can compromise the seal, allowing air to escape and negatively impacting engine performance. Loose or damaged vacuum fittings are another frequent issue, as they can disrupt the vacuum system's integrity. Cracked or damaged vacuum lines also contribute to leaks, affecting the overall vacuum pressure necessary for optimal engine operation. Lastly, a malfunctioning Positive Crankcase Ventilation (PCV) valve can introduce unwanted air into the system, further complicating the vacuum dynamics. By regularly inspecting these components and addressing any signs of wear or damage, DIYers can maintain their Miata's performance and efficiency, ensuring a smooth driving experience.
Addressing a vacuum leak in your 2020 Mazda MX-5 Miata is crucial for maintaining optimal engine performance and ensuring safety on the road. A vacuum leak can lead to rough idling, stalling, and decreased fuel efficiency, which not only affects your driving experience but can also result in increased fuel costs. Moreover, if left unattended, a vacuum leak may cause further damage to engine components, leading to more expensive repairs down the line. Additionally, it can interfere with emissions control systems, potentially resulting in a failed emissions test, which could have legal implications. Most importantly, a vacuum leak can compromise critical systems such as braking, posing serious safety risks. Therefore, it is essential to address any signs of a vacuum leak promptly to safeguard your vehicle's performance and your safety.
