What are the consequences of not replacing the exhaust valve on the Sail 3?
2 Answers
The impacts of not replacing the exhaust valve on the Sail 3 are as follows: 1. It will be unable to control the amount of exhaust gas recirculation. Excessive exhaust gas participating in recirculation will affect the concentration of the air-fuel mixture, potentially causing difficulties in starting, engine shaking, unstable idling, and weak acceleration, all of which can impair engine performance. 2. If the exhaust valve is damaged, it may lead to the car burning engine oil, with blue smoke coming from the exhaust pipe. The exhaust valve functions to separate oil and gas; under normal operation, it only draws in exhaust gas and not oil. When the exhaust valve is damaged, it loses its oil-gas separation capability, potentially sucking in oil along with the gas, allowing oil to enter the combustion chamber, resulting in oil burning and blue smoke emission.
I've seen cases where the EGR valve on the Sail 3 wasn't replaced, and the consequences were significant. This component, called the EGR valve, controls the recirculation of exhaust gases back into the engine. If not replaced in time, the valve can get stuck due to carbon buildup. The engine then performs poorly, shaking noticeably at idle, with weak acceleration and increased fuel consumption. Long-term neglect can lead to carbon deposits blocking the exhaust passages, potentially triggering the engine light, increasing the risk of piston ring wear, and even causing a breakdown on the road. Repair costs can double; I once helped a friend deal with this—replacing the valve cost just a few hundred, but delaying it led to an engine overhaul costing thousands. In short, regular checks of the EGR valve are a wise choice to prevent minor issues from becoming major headaches, ensuring smooth and safe driving. Don't skimp on the small expense—it's worth it for peace of mind on the road.
