How do you adjust the valves on a 95 Nissan 200sx?

To adjust the valves on a 1995 Nissan 200SX, first ensure the engine is cool and then remove the valve cover. Rotate the engine to bring the number one cylinder to top dead center (TDC) on the compression stroke. Use a feeler gauge to check the valve clearances and adjust them by loosening the lock nut and turning the adjustment screw to the specified clearance. Finally, recheck the clearances and reassemble the valve cover.
