To adjust the valves on a 1978 Chevette, start by ensuring the engine is cold. Remove the valve cover, then rotate the engine to align the timing mark on the crankshaft with the TDC mark on the timing cover for cylinder number one. Use a feeler gauge to check the clearance between the rocker arm and the valve stem; the specifications are typically around 0.008 inches for intake and 0.010 inches for exhaust. Adjust the rocker arms by loosening the lock nut and turning the adjusting screw until the proper clearance is achieved, then retighten the lock nut and repeat for the remaining cylinders.
