What is Valve Tappet?

Valve Tappet clearance is the space between top of the valve stem and rocker arm. It’s purpose is to allow for some mechanical expansion and lengthening of the valve stem and engine push rods as the engine warms up.This clearance is also called valve lash.

The importance of Valve Tappet / Valve Lifter

If insufficient tappet is set when engine is cold the valves will not fully close when the engine warms up and will lead to early opening of valves. If too much tappet is provided, then, when the engine warms up there will be some clearance that will lead to lost motion. Lost motion means that as the cam tries to open the valve the push rod and rocker arm moves to first take up the clearance before touching the valve, to open the valve. The result is late opening of the valve.

Please check your car model correctly before you order.
