Can the Crankshaft Ventilation Pipe Be Removed?

[MacAubree]

Crankshaft ventilation pipe can be removed, but it is not environmentally friendly, and the throttle body and idle valve are more likely to get dirty, which will affect exhaust emissions and engine efficiency. Function of the Vehicle Ventilation Pipe: The main function of the vehicle ventilation pipe is to extract exhaust gases in certain specific engines, redirecting part of the exhaust gases back to the intake manifold, where they mix with fresh air-fuel mixture and re-enter the cylinders to participate in combustion, thereby improving emissions. Impact on Engine Performance: If the ventilation pipe is not connected to the exhaust valve, it will be impossible to control the amount of exhaust gas recirculation. Excessive exhaust gas recirculation will affect the ignition and performance of the air-fuel mixture, thus impacting the engine's power output, especially during idle, low speed, light load, and cold engine conditions, where recirculated exhaust gases will significantly affect engine performance.
