What are the symptoms of a faulty EA888 PCV valve?

Here are the symptoms of a faulty EA888 PCV valve: 1. Exhaust: Sudden occurrence of extensive smoke from the exhaust (similar to that from a fire extinguisher), white smoke at idle, and blue smoke during sudden acceleration or heavy throttle. The cause is engine oil entering the exhaust pipe. 2. Odor: Accompanied by a strong burning rubber smell, which is very unpleasant. This is not the normal smell of burning engine oil. The cause is related to the catalytic converter. 3. Engine shaking: At idle, pulling out the engine oil dipstick does not cause vibration, but opening the engine oil cap should normally create suction. The dashboard warning light will illuminate.
If the EA888 engine's exhaust gas recirculation (EGR) valve fails, the most common issue is that annoying yellow check engine light suddenly illuminating on the dashboard. The car will feel particularly shaky when idling at red lights, as if vibrating, and sometimes the engine may produce a sputtering sound that just doesn't sound right. Even worse, there's noticeable sluggishness during acceleration – you press the gas pedal but get no power, especially evident when overtaking. Fuel consumption also inexplicably increases, adding significant costs to monthly refueling expenses. If not repaired promptly, the exhaust system may become clogged, potentially leading to more severe engine damage. I recommend visiting a repair shop as soon as possible for specialized computer diagnostics – replacing the valve usually solves the problem. Don't delay to avoid incurring unnecessary additional expenses.
I experienced a faulty exhaust valve issue with my EA888-powered vehicle. At that time, the car felt unstable when driving in the city, and the steering wheel kept shaking at idle, which made me quite uncomfortable. The most frustrating part was the nearly 20% increase in fuel consumption, costing me dozens of dollars extra on gas each month. After inspection, the mechanic said the valve was stuck, preventing exhaust gas recirculation and affecting combustion. Looking back, sluggish acceleration was also a sign, with noticeably insufficient power when overtaking on the highway. Fortunately, everything returned to normal after repairs, so it's important to always pay attention to your car's condition.
