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 diagnosing a vacuum leak in a 1995 Hyundai Elantra, it's essential to focus on several common issues that could be the source of the problem. One of the primary culprits is leaking vacuum hoses, which can deteriorate over time due to heat and wear, leading to air entering the system improperly. Additionally, gaskets and seals, particularly around the intake manifold and throttle body, can also fail, allowing air to escape and disrupting the engine's air-fuel mixture. Bad actuators and valves, which control various engine functions, may also contribute to vacuum leaks, so inspecting these components is crucial. Furthermore, the EGR system and engine vacuum system should be examined for any signs of leaks. Symptoms such as unusual engine noise, fluctuating RPMs, or changes in performance can indicate a vacuum leak, making it important to pay attention to these warning signs. By systematically checking these common areas, DIYers can effectively identify and address vacuum leaks, ensuring their Hyundai Elantra runs smoothly.
To effectively diagnose and fix a vacuum leak in your 1995 Hyundai Elantra, start with a thorough visual inspection of all vacuum hoses, looking for any signs of wear such as cracks or disconnections. Pay close attention to the intake manifold gaskets, vacuum pump, and throttle body, as these areas are common culprits for leaks. Next, listen for any hissing sounds while the engine is running, as these noises can indicate a vacuum leak. If you have access to diagnostic tools, utilize a diagnostic analyzer to assess the engine's performance; low CO readings and fluctuating HC levels can help pinpoint the issue. Additionally, monitor for symptoms like rough or unstable idling, which often accompany vacuum leaks. Common causes include damaged hoses or faulty gaskets, so addressing these issues promptly is crucial for maintaining your vehicle's performance and preventing further complications. By following this structured approach, you can efficiently identify and resolve vacuum leaks, ensuring your Elantra runs smoothly.
