Valve Lash Wrench
An engine valve lash wrench is a specialized tool used to adjust the valve clearance, also known as valve lash, in an internal combustion engine. It is typically a thin, flat wrench with a specific size and shape that is designed to fit the adjusting screw on the rocker arm. The valve lash wrench is used to turn the adjusting screw, adjusting the clearance between the valve stem and rocker arm. The valve lash is crucial for proper engine performance and should be checked and adjusted periodically to ensure optimal engine operation. The valve lash wrench is used in conjunction with a feeler gauge, which is used to measure the clearance between the valve stem and rocker arm. Once the valve clearance is measured, the valve lash wrench is used to make the necessary adjustments to achieve the proper clearance.

When selecting a valve lash wrench, first measure and confirm the rocker arm nut socket size as well as the set screw size which the tool will need to be able to match (for example, theProform 66779 valve lash wrench is compatible with a 7/16" rocker arm nut and 1/8 " set screw). From the remaining compatible options, choose the valve lash wrench that best fits your application needs as well as your budget.
