Four-Cylinder Engine Valve Clearance Adjustment Method?

[McCassandra]

Adjustment methods are as follows: 1. During assembly, use standard shims to measure the valve clearance value and place them on the valve pushrod to compensate for the gap. Replace the shims when they wear out. 2. Use hydraulic lifters, which automatically adjust the clearance. No adjustment is needed unless the hydraulic lifters are damaged. 3. For older gasoline engines, adjust the screw on the rocker arm to compensate for the gap when the valve is fully closed. 4. Valve adjustment sequence. Set the engine to the first cylinder working, adjust the intake and exhaust of the fourth cylinder, the intake of the third cylinder, and the exhaust of the second cylinder! Then set the engine to the fourth cylinder working, adjust the intake and exhaust of the first cylinder, the intake of the second cylinder, and the exhaust of the third cylinder.
