How to Fix Insufficient Cylinder Compression in a Car?
2 Answers
Methods to repair insufficient cylinder compression in a car: 1. Open the engine and remove the cylinder head to check if the valves are not sealing properly or if the valve seals are leaking, then replace the valve seals; 2. If the cylinder friction gap is too large and within repairable limits, you can install cylinder liners and then perform cylinder boring; 3. If there is piston ring blow-by, replace the pistons and piston rings with new ones. If insufficient cylinder compression occurs, it should be repaired at a 4S shop promptly. Insufficient cylinder compression can cause difficulty in ignition, incomplete combustion, engine shaking, and performance degradation. The vehicle's seals deteriorate with age, which is why the engine's performance declines over time.
I've seen quite a few cases of insufficient cylinder pressure, usually caused by wear and tear of internal engine components, such as worn piston rings or scratches on the cylinder walls. I recommend performing a compression test first, using a pressure gauge to measure the pressure in each cylinder. If the readings are low, it indicates a problem. Common causes also include poor valve sealing or timing belt misalignment. To fix it, the engine needs to be disassembled for inspection. If it's a ring issue, replace them with new ones. If the cylinder is scratched, it needs to be rebored for repair. If not fixed promptly, the car may experience difficulty starting, slow acceleration, and increased fuel consumption. In severe cases, it could damage other components. Spend some money to find a reliable repair shop and address the issue early to prevent small problems from escalating. Remember, checking the oil and its quality during routine maintenance can help reduce this type of wear.
