Is it necessary to replace the valve cover?

[McAngelo]

It is necessary to replace the valve cover, as replacement helps maintain the car's performance. Here is a detailed introduction about the car throttle: 1. Overview: The throttle is a controllable valve that regulates air intake into the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. Connected to the air filter at the top and the engine block at the bottom, it is referred to as the throat of the car engine. 2. Classification: Throttles are divided into two types: traditional cable-operated and electronic. In traditional engines, the throttle control mechanism operates via a cable (flexible steel wire) or linkage rod, connecting the accelerator pedal at one end and the throttle linkage plate at the other. Electronic throttles primarily use a throttle position sensor to adjust the throttle opening angle based on the engine's energy requirements, thereby regulating the amount of air intake.
