Why Is The Inlet Valve Clearance Always Smaller Than The Exhaust Valve Clearance? Why is the inlet valve clearance always smaller than the exhaust valve clearance? … The exhaust valve has a near constant flow of very hot air. Therefor the exhaust valve will expand more then the inlet valve and need more clearance because
How Do You Set Valves? When you adjust a valve, you’re not adjusting the valve itself but compensating for that wear, letting the valve open and close as efficiently as possible.

At What Temperature Does The Exhaust Valve Open? When the valve opens and exhaust gas begins to flow out from under it, the valve is heated not only on the top of its head by combustion itself but the back side of it is heated as well by exhaust gas, whose temperature can be as
