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 Mitsubishi Eclipse Cross, it's essential to adopt a methodical diagnostic approach. Start by inspecting the vacuum hoses for any visible signs of wear, cracks, or disconnections, as these are often the simplest and most common sources of leaks. Next, examine the gaskets and seals, particularly the valve cover and intake manifold gaskets, for any signs of leakage or deterioration. If these components appear intact, move on to checking the actuators and valves to ensure they are functioning correctly, as malfunctioning parts can also contribute to vacuum leaks. Additionally, if your vehicle is displaying a P0441 code, pay special attention to the leak detection pump and the associated vacuum hoses connected to the purge valve. If you encounter persistent issues or complex mechanical problems, such as valve cover leaks or unusual noises, it may be prudent to seek a professional inspection to ensure thorough diagnostics and repairs. By following this structured approach, you can effectively identify and resolve vacuum leaks, ensuring your Mitsubishi Eclipse Cross operates smoothly.
When diagnosing a vacuum leak in your Mitsubishi Eclipse Cross, it's essential to be aware of the common problems that can arise. One frequent issue is the deterioration of vacuum hoses, which can develop cracks or become brittle over time, leading to air leaks. Additionally, leaking gaskets and seals, particularly around the intake manifold, can also contribute to vacuum loss, affecting engine performance. Bad actuators and valves, which control various engine functions, may fail and create vacuum leaks as well. Drivers often report symptoms such as rough idling, decreased fuel efficiency, and an illuminated Check Engine Light, all of which can signal a vacuum leak. By understanding these common failure modes, you can better troubleshoot your vehicle and take the necessary steps to fix the issue, ensuring your Mitsubishi Eclipse Cross runs smoothly.
Addressing a vacuum leak in your Mitsubishi Eclipse Cross is not just a matter of routine maintenance; it is a critical step in ensuring the longevity and performance of your vehicle. Ignoring symptoms such as an illuminated check engine light or erratic engine performance can lead to severe consequences, including oil and coolant leaks that may compromise engine integrity. The presence of vacuum leaks can also result in poor fuel efficiency, which not only affects your wallet but can also lead to more extensive repairs down the line. Additionally, issues like valve cover leaks can cause oil seepage, risking engine damage if left unattended. The urgency to resolve these leaks is further underscored by the potential for internal leaks in the Exhaust Gas Recirculation (EGR) system, which can create lean conditions and misfires, jeopardizing your vehicle's safety and reliability. By promptly addressing vacuum leaks, you not only enhance your Mitsubishi Eclipse Cross's performance but also safeguard against costly repairs and ensure a safer driving experience.
