Is It Necessary to Repair a Car with One Bad Cylinder?

If one cylinder in a car is damaged, all four cylinders need to be bored. Here is a related introduction to car cylinders: Introduction to Car Cylinders: A car cylinder is a cylindrical metal component that guides the piston in linear reciprocating motion inside the cylinder. In the engine cylinder, air converts thermal energy into mechanical energy through expansion. In the compressor cylinder, gas is compressed by the piston to increase pressure. The housing of turbines, rotary piston engines, etc., is also commonly referred to as a cylinder. Maintenance of Car Cylinders: When reassembling after cylinder inspection and repair, all parts must be thoroughly cleaned, with special attention to preventing the sealing rings from being sheared or damaged. Pay attention to the installation direction of dynamic sealing rings. During use, regularly inspect all parts of the cylinder for any abnormalities and check for looseness in all connecting parts. For cylinders installed with pins, the moving parts should be lubricated regularly. If a cylinder is removed and not used for a long time, all machined surfaces should be coated with anti-rust oil, and the intake and exhaust ports should be covered with dust plugs.
If one cylinder is malfunctioning, it really needs to be addressed. As someone who frequently deals with cars, I can explain: an engine has multiple cylinders to maintain balanced operation. Losing one is like a person missing a leg—the car will shake violently, especially when idling, making the steering wheel feel noticeably wobbly. Power output drops significantly, making overtaking and acceleration difficult, and on highways, the delayed response can increase accident risks. Fuel consumption will definitely rise, as the engine has to work harder to compensate, typically costing 10-20% more in fuel. Ignoring the issue can turn a small problem into a big one: the unbalanced forces accelerate wear on other cylinders and components, such as pistons or the crankshaft, gradually leading to engine failure—repairs at that stage could cost tens of thousands. Safety-wise, insufficient power during rainy conditions or emergency braking heightens the danger. I recommend taking the car to a reliable repair shop immediately to check whether it’s a spark plug issue or actual cylinder damage. Fixing it early ensures peace of mind, saves money, and keeps the car running smoothly. Don’t delay or drive it as-is—long-term, it’s just not worth it.
This is a pretty common issue. Having driven for decades, I can tell you that a faulty cylinder should never be ignored. The car shakes like a massage chair when driving, especially noticeable when stopping or starting—it's really uncomfortable. The power just isn't there; climbing hills feels like a struggle, and overtaking becomes hesitant, which can easily lead to accidents. Increased fuel consumption is inevitable, and your wallet will feel the pinch. Repair costs depend on the situation: minor issues like ignition system failures can be fixed for a few hundred, but serious problems like cylinder wall damage could cost thousands. The consequences of not fixing it are worse: accelerated wear and tear, reduced engine lifespan, and eventually, replacing the entire engine will cost even more. My advice is not to rush into repairs—first, get a professional diagnosis to pinpoint the issue before deciding. If the car is relatively new or of good quality, fixing it saves you from wasting money; for older cars, weigh whether it's worth repairing or replacing. In short, don't take risks just to save money.
