How to Adjust the Valves on an Eight-Cylinder Engine?

[SanAmy]

Here is the method for adjusting the valves on an eight-cylinder engine: 1. Set the first cylinder to top dead center (TDC), then adjust the intake and exhaust valves of the first cylinder, as well as the exhaust valves of the fifth, fourth, and second cylinders. Leave the sixth cylinder untouched, and adjust the intake valves of the third, seventh, and eighth cylinders. 2. Rotate the crankshaft 360 degrees to position the sixth cylinder piston at TDC, then adjust the intake and exhaust valves of the sixth cylinder, as well as the exhaust valves of the third, seventh, and eighth cylinders. Leave the first cylinder untouched, and adjust the intake valves of the fifth, fourth, and second cylinders. Below is additional information about valves: 1. The function of valves is to intake air into the engine and expel exhaust gases after combustion. 2. In terms of engine structure, valves are divided into intake and exhaust valves. The intake valve's role is to draw air into the engine to mix with fuel for combustion, while the exhaust valve's role is to expel the post-combustion exhaust gases and dissipate heat.
