Valve Tappet 22226-25001 This thing is the design goal is simple. Because we have a car engine valve wear, and there is the problem of thermal expansion and contraction, if the mechanical-transmission, is likely to cause the valve closed lax, or the valve does not sound normal (loud), while the impact of the car's power and comfort . Use engine oil pressure to open the valve, the oil viscosity and temperature have a great relationship, in general just started, the temperature of the oil has not yet reached normal car, causing the viscosity is not suitable for hydraulic tappets the normal operating value, hydraulic tappets tightness decreases, causing the valve gap, generating noise, etc. after the car engine has reached normal operating temperature, the valve will be reduced until there is no sound. If a larger valve can hear the sound, you should check the hydraulic tappets are not worn and need replacing. Because of its wear and tear caused by the oil inside the tightness out of action, the gap between the valve and valve tempo is too large, the sound appeared. By the way: There is no engine valve tappet clearance is always there, only produce small changes in cold and hot time. When the tappet engine is working properly, or it is no valve clearance gap enough to make us hear the sound.
