What is the gap on the valves on a 2004 5.9 cummins and how do you set them?

The valve clearance for a 2004 5.9 Cummins engine is typically set at 0.010 inches (0.25 mm) for the intake valves and 0.020 inches (0.51 mm) for the exhaust valves. To set the valve clearance, first, ensure the engine is cold. Rotate the engine to the top dead center (TDC) of the compression stroke for the cylinder you are adjusting, then use a feeler gauge to measure the gap and adjust accordingly using the rocker arm adjuster to achieve the specified clearance.
