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 tackling vacuum leaks in a 2015 Fiat 500, it's essential to recognize the various common problems that can arise. One of the primary culprits is leaking vacuum hoses, which can deteriorate over time and lead to a loss of engine performance. Additionally, gaskets and seals may also fail, contributing to vacuum leaks and potentially causing oil leaks that can further complicate engine issues. Another significant concern is the vacuum pump, where leaks often occur at the gaskets, leading to decreased efficiency and increased repair costs. Furthermore, the turbo compressor can become a source of major problems if it disassembles, with repair costs averaging around $2,000. It's also worth noting that vacuum leaks can result in engine overheating, often linked to a malfunctioning thermostat or insufficient coolant levels. Lastly, electrical issues, such as glitches and window regulator failures, may also be indirectly related to vacuum leaks, underscoring the importance of regular maintenance and prompt inspections to prevent these complications from escalating. By understanding these common problems, DIY enthusiasts can better diagnose and address vacuum leak issues in their Fiat 500, ensuring optimal vehicle performance.
To effectively diagnose a vacuum leak in your 2015 Fiat 500, begin by listening for any unusual hissing or whistling noises emanating from the engine bay while the engine is running, as these sounds often signal a leak. Next, conduct a thorough visual inspection of the vacuum hoses, gaskets, and seals, looking for any signs of wear, cracks, or damage that could be contributing to the issue. Pay particular attention to the vacuum pump area, as oil leaks here can indicate a problem with the pump itself. Following this, test the vacuum line for leaks, which can help pinpoint the source of the issue. Additionally, inspect the PCV valve to ensure it is functioning properly, as a malfunctioning valve can lead to pressure buildup and exacerbate leaks. If these steps do not reveal the source of the vacuum leak, or if you feel uncertain about the diagnosis, it may be wise to consult a mechanic or a Fiat dealership for professional assistance. By following this structured approach, you can systematically identify and address vacuum leaks in your vehicle.
