Are the rocker arms for 94 s10o 4.3 self adjusting?

Yes, the rocker arms on a 1994 Chevrolet S-10 with a 4.3L V6 engine are self-adjusting. This is due to the design of the hydraulic lifters used in the engine, which automatically adjust to maintain proper valve clearance as the engine operates. This feature simplifies maintenance, as it eliminates the need for manual adjustments to the rocker arms.
