What are the symptoms of a faulty exhaust valve in the Magotan?
2 Answers
If the exhaust valve in the Magotan is faulty, it will exhibit the following symptoms: 1. When opening the oil filler cap, if there is severe suction, it indicates a problem with the exhaust valve. 2. Sudden emission of large amounts of smoke from the exhaust (similar to that from a fire extinguisher), white smoke at idle, and blue smoke during rapid acceleration or heavy throttle. This is caused by oil entering the exhaust pipe. 3. Odor, which is also a critical indicator. There will be a strong, pungent burnt rubber smell, very foul, unlike the normal exhaust smell from burning oil. 4. Additionally, if a whistling sound is heard, it can almost certainly be confirmed that the exhaust valve is faulty. 5. If left unrepaired, in severe cases, a large amount of oil can enter the cylinder. Since liquids are incompressible, the piston and cylinder can be damaged, leading to engine seizure. Therefore, if the exhaust valve is damaged, it must be repaired by a professional as soon as possible. A faulty exhaust valve can cause oil burning, leading to rapid oil consumption and increased oil usage.
When the exhaust valve of my Magotan malfunctioned while driving, my first impression was severe engine shaking, unstable idling, and fluctuating RPMs. The car lacked power during acceleration. Fuel consumption skyrocketed—previously, half a tank would last 400 km on the highway, but now a full tank was gone after just 250 km. The exhaust emitted a pungent smell and often produced black smoke, clear signs of incomplete combustion. The check engine light kept coming on as a reminder to get it checked—don't ignore it. Over time, severe carbon buildup can affect the entire engine, even fouling the spark plugs, which shortens the car's lifespan. I recommend heading to a repair shop as soon as you notice these symptoms—don't wait for bigger problems. Pay attention to these changes during daily driving to protect your car and save on fuel costs. Safety should always come first.
