How do you adjust the valve clearance on Chevy Metro 1998 4 cylinders were to use the feeler gauge?

To adjust the valve clearance on a 1998 Chevy Metro with a 4-cylinder engine, first, ensure the engine is cold and remove the valve cover. Rotate the crankshaft to align the timing mark to TDC (top dead center) on the compression stroke for the cylinder you’re adjusting. Use a feeler gauge to check the clearance between the rocker arm and the valve stem; it should be within the specified range (usually around 0.008 inches for intake and 0.010 inches for exhaust). If adjustments are needed, loosen the lock nut and turn the adjustment screw to achieve the correct clearance, then recheck with the feeler gauge and reassemble the valve cover.
