To ensure uninterrupted and noiseless motion of valve-controlled components, the Chevrolet Express Lash Adjuster compensates for clearance allowances. The Lash Adjuster, a tappet or valve lifter in modern terminology, has the characteristic that it lifts the valve to the desired position to match the cam profile. Thus, the engine can breathe efficiently, preventing metal to metal wear and tear which would have shortened service life. Early designs' engines applied solid lifters that required periodic feeler-gauge adjustments. In contrast, the hydraulic Lash Adjuster fitted in most Express engines uses pressurized oil to expand internally, automatically maintaining the critical gap despite changes due to heating and cooling of component parts. Some performance years also applied a roller style Lash Adjuster that rides on a small wheel, so friction is reduced and there is more efficient running than flat followers, although it still has the same self-adjusting hydraulic core. The essential differences with these types center around their maintenance and drag. Solid versions will bring you more rev tolerance but at the expense of having to make manual adjustments. That is to say, in a Chevrolet Express van, hydraulic and roller units allow you to set and forget, and they run smoother too. The tailored design of the Lash Adjuster brings increased valve train life and reduced idle instability to Chevrolet drivers without additional upkeep.
