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 Mazda 6, begin by inspecting the vacuum hoses, as they are often the most straightforward source of leaks. Look for any cracks, disconnections, or loose fittings that could disrupt airflow. Next, examine the gaskets and seals around the intake manifold and other connections; these can wear out over time and lead to leaks. Ensure that all surfaces are clean and that components are tightened correctly during reassembly to prevent future issues. After addressing these areas, check the actuators and valves, as malfunctioning parts can also contribute to vacuum leaks. For a more thorough diagnosis, consider using propane enrichment or carb cleaner to identify leaks, but always prioritize safety by working with a cold engine and having a fire extinguisher on hand. By following this methodical approach, you can effectively identify and resolve vacuum leaks, ensuring your Mazda 6 runs smoothly and efficiently.
When dealing with vacuum leaks in a Mazda 6, it's essential to understand the common problems that can arise. One frequent issue is cracked or damaged vacuum hoses, which can lead to a loss of engine performance and increased fuel consumption. Additionally, leaking gaskets and seals, particularly around the intake manifold, can create air leaks that disrupt the air-fuel mixture, resulting in rough idling or stalling. Bad actuators and valves may also contribute to vacuum leaks, as they can fail to maintain proper pressure within the system. It's crucial to conduct a thorough visual inspection and utilize a spray test to pinpoint these issues accurately. By being aware of these common failure modes, you can take the necessary steps to repair or replace the affected components, ensuring your Mazda 6 runs smoothly and efficiently.
Addressing a vacuum leak in your Mazda 6 is not just a matter of routine maintenance; it is a critical step in ensuring the safety and longevity of your vehicle. Ignoring the symptoms of a vacuum leak, such as an illuminated check engine light or erratic engine performance, can lead to a lean air-fuel mixture that compromises combustion efficiency. This not only results in poor engine performance but can also escalate into more severe issues, including misfiring and potential engine damage. The urgency to fix a vacuum leak is underscored by the risk of further complications, such as oil and coolant leaks, which can lead to costly repairs if left unaddressed. Moreover, a vacuum leak can significantly impact fuel efficiency, leading to increased operational costs over time. By promptly diagnosing and repairing any leaks, you not only enhance your vehicle's performance but also safeguard against the safety risks associated with engine malfunctions. Therefore, taking immediate action to address a vacuum leak is essential for maintaining optimal engine function and ensuring a safe driving experience.
