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 Toyota MR2, it's essential to adopt a systematic diagnostic approach. Start with the simplest methods, such as the "ciggy test," where you can use smoke from a lit cigarette to visually identify leaks around the engine. If smoke is drawn into any cracks or gaps, you've pinpointed a potential issue. Next, consider using propane or carb cleaner to further isolate the leak; spraying these substances around suspected areas can cause the engine to rev if a leak is present. Don't overlook the importance of checking the PCV valve, as a malfunctioning valve can significantly impact engine performance and contribute to vacuum leaks. If you suspect that the vacuum hoses are worn or damaged, replacing them with a comprehensive kit, like the one from KBOX, can be a straightforward solution. Finally, performing a tune-up by replacing the cap, rotor, wires, and plugs can help resolve any lingering idle issues related to vacuum leaks. By following this methodical approach, you can effectively diagnose and address vacuum leaks, ensuring your Toyota MR2 runs smoothly.
When tackling the issue of a vacuum leak in your Toyota MR2, it's essential to understand the common problems that can arise within the vacuum system. A vacuum leak can lead to a variety of performance issues, including rough idling, decreased fuel efficiency, and increased emissions. Common culprits include cracked or worn vacuum hoses, which can deteriorate over time due to heat and exposure to engine fluids. Additionally, gaskets around the intake manifold and throttle body can fail, leading to air entering the system where it shouldn't. Less frequently, issues may arise from a malfunctioning brake booster or even a faulty PCV valve. By being aware of these potential failure modes, you can more effectively diagnose the source of the leak and take the necessary steps to repair it, ensuring your MR2 runs smoothly and efficiently.
Addressing a vacuum leak in your Toyota MR2 is not just a matter of routine maintenance; it is an urgent necessity that can prevent serious complications. Ignoring the symptoms of a vacuum leak can lead to erratic engine performance, which may manifest as rough idling or stalling, creating a hazardous driving situation. Additionally, a vacuum leak can cause the engine to run lean, resulting in poor fuel efficiency and increased emissions, which not only affects your wallet but also risks failing emissions tests. Over time, the strain of running lean can damage critical components like the exhaust system and catalytic converter, leading to costly repairs. Furthermore, the check engine light may illuminate, signaling that immediate attention is required. Neglecting this warning can exacerbate existing issues, ultimately compromising the overall health and longevity of your vehicle. Therefore, it is crucial to address any vacuum leaks promptly to ensure your Toyota MR2 operates safely and efficiently, safeguarding both your investment and your driving experience.
